Savage and other actions that use a barrel nut require a "go gage". The barrel is screwed into the action to the right depth and the barrel nut locks it in place.

Savage has the barrel nut for perfect head spacing. The floating bolt head keeps it from binding and with even pressure. That solves a lot of problems. 👍

I’ve had 4 prefit barrels for Bighorn actions and 1 for a Tikka action. 2/4 bighorn ones were barrel nut prefits and the other 2 were shouldered. All the proof prefits I’ve had shot lights out. The barrel nut prefits are kind of a pain comparatively, but functional once installed. I always check headspace with a no go gauge to be sure, and I haven’t had a shouldered barrel fail. Torquing is pretty easy with a barrel Vice and wrench.

Gunsmith here. You guys are painting a pretty simplistic picture of prefit barrels. I’m shocked that you never mentioned headspace gauges to verify that your prefit barrel is chambered correctly. The fact is that the difference between a “Go” and “No Go” gauge is only .006. You should ALWAYS check this and never assume. For the viewer who may be considering this, here’s what you’ll actually need to build one of these rifles yourself: 1.) proper barrel vise. If you’re doing a powerful magnum cartridge like a .300 Win Mag or 300 PRC, barrel torque needs to be 120 ft lbs and you’re not going to hold that in a conventional vise without completely ruining the finish on the barrel 2.) Ft lb and in lb torque wrenches. Barrel is ft lb and action to stock and other accessories are in lbs. 3.) “Go” and “No Go” gauges for the cartridge you plan to use to verify correct headspace4.) action wrench to fit your action and barrel nut wrench if required. A couple of other notes: You can only choose a cartridge for your prefit barrel that matches your action and bolt face. If you have a standard short action, you couldn’t use a barrel chambered in 6.5 PRC for example because that cartridge uses a magnum bolt face. In the same way, If you have a long action with magnum bolt face, you couldn’t drop down to a .30-06 or .270 win because those cartridges use a standard bolt face and not a magnum. Finally, gunsmiths are as much to blame for prefits as anyone. Customers are tired of spending hard-earned money to be treated like a nuisance rather than a customer and waiting months for a simple rebarrel. Prefits are often “good enough” for most hunters and even PRS competitors who’s score depends on impacts and not group size like F-class or benchrest. If you still want the most accuracy possible from your rifle, that barrel needs to be fitted and chambered individually to that action. I personally don’t offer prefits simply because it puts the burden on the customer if something isn’t correct. I do offer prefits for rifles that I’ve built previously because I measure each action and create an actual blueprint with the measured headspace and barrel tenon dimensions. This is saved by rifle serial number.

Should have been in the 6.8 Western 😄🇦🇺

This is a great video! You fellers are having too much fun!!

Thanks for the video! Last year, I built a bolt action 22 Creedmoor based on the Aero Precision Solus platform. I specified a pre-fit and spun it on myself. Headspaced properly with no problems. The rifle shoots great!

Sir you have expanded my knowledge and understanding over cartridges I didn’t even know existed. You are an amazing knowledgeable expert. I am extremely grateful and very thankful to have you’re informational videos at hand.

With all you have in it a simple go/no go gauge be cheap insurance. Once again yall put together good show thank you

Buy a Savage 110 or 10 action and change barrels whenever you want....

This was a very cool video Ron, thanks

I love Savage rifles and have replaced barrels before on them. I purchased a 12FV in 308 from a friend that was moving but the existing barrel was damaged from neglect. Everything else seemed fine so I gave him a C note for it. I took the barrel off, with the barrel nut system it was a breeze. The rest of the rifle was in really good shape so I ordered a new 26" Palma contour barrel in 6.5 Creedmoor from EAB and screwed it on and set the headspace, it even came with a barrel nut wrench. The EAB barrel was one of the cheaper ones offered but with my handloads it shot to 1/2" first time out. With a short breakin and a little load development that rifle put 5 rounds into .330" at 100 yards and all that for half the price of a new Axis II.

Awesome video really enjoyed you two guys

Great Content Ron and JVB. There has been good things said about go gauging and checking head space etc. if you are planning to do this. It would be natural to assume you do these safety things.

I wasn't happy with the factory barrel on my Savage .308 Win., so I ordered a new barrel, go and no go gauges, and action wrench, and built a barrel vise. Then it was a simple matter of following the instructions. The end result was well worth it, as the new barrel is more accurate and easier to clean to boot.

Nice show , but i love my 1950 winchester m70 in 270 shoots like a dream .and i love wood stocks and traditional barrels.

Good Glass is the top consideration. MOA is good enough for hunting sub 500 yards.

I burned out a barrel. Over heated. Ive done a couple of barrel replacements.... neither of them shoot well. Cheap barrel? Yeah, but is that why it doesn't shoot? Its a long journey..... I'll let you know when I get there!

Supporting your local gunsmith is worth it. Also he will guarantee his work and fix any problems that come up.

I have prefit barrels on two Origins. Love them both, but the barrel nut version is lighter than the shouldered version.

you can consider yourself lucky if you can swap the barrel yourself. if you live in Germany for example, you aren't allowed to modify essential parts ot the weapon yourself, you need to be or hire a gunsmith.

I have three rifles with the prefit barrels on them 2 tikka and a Remington and all of I used a no/ go gauge to check heads spacing. The Remington I had to used a barrel. If ever replace that barrel I can reuse the barrel nut.

Excellent topic and impeccable timing too since yesterday I was once again thinking about doing something similar hopefully 🙏 in the near future. As a lefty shooter even in 2024 it’s tough to find a left handed rifle in cartridges outside of a few common ones. I have a right handed Savage M110 Long Range Hunter in 300 WSM and I like the gun and it shoots well but for me it is not super handy in the field and I can’t take the muzzle brake off to eventually put a suppressor on it. The only rifles that I can find left hand with a threaded barrel and in 300 WSM are the Savage 110 Ultralight which I like, the Savage M110 Timberline which would be similar in weight to my current rifle but with a cerakoted barrel action and threaded with a brake and a Christensen Arms Mesa in the sub $1500 category. I could go with either Savage, but part of me wants to try a different brand since all three of my rifles are Savage. I would love a Tikka but they still don’t offer a left handed 300 WSM with a threaded barrel. 300 Win Mag yes, but 300 WSM not so much. So I think that it would be cool to slowly get a part here and a part there and eventually I would be able to put together a semi custom Tikka rifle in 300 WSM that I actually want. Thanks for sharing this gentlemen 🤠🤠

Ron should interview Caleb of Brownells.

Plenty of pre-fit barrels out there for the Ruger 10/22. I've been thinking of building me a long range rifle. This way i can get it the way i want it (stock, barrel lenght, thickness, ect) hopefully without spending to much. I am a cnc machinest/ programmer and have total confidence in what to look for.

Well now the Wilson combat 4 pound .308 looks affordable!

Well that stock is not my cup of tea. I can see that its also were things are going. I bought my first synthetic stocked rifle back in 1976- I still have it. The other thing is precision manufacturing has gotten so good, that this sort of thing is now practical . I shoot a Blaser R-93 so I know all about switch barrels. If I was going to buy another rifle and I am not in the market, A John Rigby Highlander in 275 Rigby would be what I would want. In the mean time I will continue to hunt and put venison in the freezer with my old Steyr Mannlicer Model M Professional in 7 x 57 that have had since I bought it in 1976. Best 400 dollars I ever spent.

I’ve had 3 McMillan stocks within the past 2 years. One was delivered with numerous defects, and they refunded the entire stock. The other is on a custom rifle, and the stock is cracked in front of the rear pillar. Kinda ridiculous for what their stocks cost.

Great content as allways, I personally would purchase a Browning xbolt mountain long range and maybe upgrade the trigger and would b a lot lower cost than a custom built rifle

I'm building... Thx!

Easy for you guys in the US. In my country the barrel is licensed.

I really like this idea.

I got lucky, my brother knew a guy...😳It turned out he was very accomplished and a genuine smith. I gave him an old small ring mauser and he rebarrelled it to a modern 7x57. 700$ later I was driving tacks downrange🤠 Support your local smith an referr him.

I got 2 older sako 75's with heavy barrels one 223 and 22-250 and both will do under half inch love them but heavy

With that stock it will serve a duel purpose the magnesium can be shaved off for fire starting.

I love it. Do I got any blue light specials?

Sucks that in Australia, we have to register barrels as if they are their own gun. The give reason for having 2 of the same caliber.

7mm prc (AKA 7mm needsmore)😂

Carbon 6 barrels does Howa pre fits.

Thanks Ron & Joseph ,Definitely need info on where & how on these barrels!

A ton of this and a ton of that is the new catch phrase for today's kids.

20 inch 7 prc? That might be breaking 2700fps with the hornady eldx loads then.

So you gutted a 7mmPRC to a 7-08????

Replace my rem 700 barrel 30-06 with a Shilen barrel It uses a lock nut, 25.5 inch. Match grade 1-10 twist, Timney trigger, Boyds thumb hole stock, it shoots 1/4 moa at 200 yards. I am getting 3015 fps with a 165 grain Speer hunter bullet.

For $500 including shipping Pac Nor Barrels will barrel a rifle with a SS super match barrel + muzzle break and fluted and to the chamber you want. I just had my Weatherby mark 5 that Weatherby refused to take responsibly for an off-center chamber then Pac Nor barreled for me back to 300 Wby with a SS super match 27 inch - 1-10 - Polygonal rifling barrel that has now been sighted in then shoots 1 single hole it is so accurate. I am now using 3 AR 10s and one bolt rifle with Pac Nor Barrels that shoot pretty close to single hole on center target holes

As a machinist I think it’s stupid to assume that you’re going to be “within a thousandths” with every action across the board. The only actions I think are actually designed for this are Savage rifles and the copies that use the Jam nut system. You still need a go gauge. no reason to ever buy the No-go because you’re screwing it down and touching the go gauge, then locking it down with the nut.

Should make a video with parts list or links to these parts.

So I can buy a left hand action and buy a barrel for the caliber I want.

The nice thing about a new barrel on an action is the end result payoff that can be better and cheaper than a new high-end rifle at the big box stores that is to your liking!

Are those steel or carbon fiber barrels. To bad U Tube wont let you show putting that gun together, I found that really interesting. You know show the vice the tools needed ext, the torque required . You no I want to build one now. But are the special tools going to make it out of reach.

New Terminus Action, Proof Barrel Prefit > easy and accurate.

31:24 Just because a gun shoots a single 3-shot group under 0.5 MOA doesn't make it a 0.5 MOA gun. Realistically this is more like a 1 MOA gun.

I wish bolt gun prefits were as affordable as AR uppers. I'd love to try out different cartridges, especially safari magnums, before dropping $3000+ on a full custom build. Admittedly I'm a quantity over quality kind of guy.

Another great informational video! Thanks Ron and Joseph!

Love your videos Ron! Is there any actual measurable difference in projectile power lose from a bolt action to a gas or blowback operated system? Obviously gas is escaping from more than just the bore soooooooo

A 20” 7prc!?! That bullets gonna have less horsepower than if you had it chambered for 7-08! 😂 I’d love to see a follow up video with this set up shot though a chronograph or measured with radar.

Im in florida. I have some leverguns ive always used vut never more than 200 yds. Im gettin old and went to a 300 bk ar for walkin around hunting and a 6.5 grendel ar for stands. More accurate, both 1/4" at 100 and so much lighter!

This is one I need!!!

I never thought I would feel so disappointed to see a trucker hat. 😶

But not a Remington 700.......one of the most popular and cloned actions ever made.

Not really too impressed with those groups... I'm sure it'll get better as it settles in, but it's not as good as some savage, bergara, or tikkas ive shot straight out of the box....

Historical firearms and revolvers aside, I only buy guns that I can change the barrel on without a gunsmith.

For the love of God! Why is he calling it a shasie?? lol

Savage or ramage

I can really appreciate this video but i feel your pricing reflects what these companies sell the products to you for... not what they sell them to us for. I priced everything you have and it came to a grand total of $4,094 before taxes and before any shipping charges. So basically over 4k and you still don't have an optic, rail, rings, rails to mount a bipod... If you dont have the tools to build it that's an additional cost for the first build. If you build the rifle and screw it up... depending on what you did wrong... you wasted thousands of dollars and quite possibly injured yourself and/or someone else.

That’s a nice gun to be sure. Mr JVB has expensive taste in rifles. 😂

Shassy? Ch-ass-eee

Chassis = ch ch, like cheese. Not sh sh like sheep.

Headspace gauges? Dangerous and irresponsible to recommend swapping barrels without gauges.

Woah,that's smaller then a half dollor.

I absolutely despise this new fad w these metal chassis stocks . Light weight this n that. Puny rounds being chosen because all of a sudden nobody can take any recoil . Not sur why we always did before wo problems. Omg Wtf has happened to all the men out there? Yall gone so soft its ridiculous. I remember the days when men were men. And acted like it.

Tbh i think this vdo is bull 1/2 in with factory loads let see it bet you cant

Don’t do it, barrel nuts are ugly and it’s unlikely a perfect fit.

Well…huh….new vehicles are great. But using your tire metaphor..no matter the age the cars will someday need new tires..correct. But you’re pushing spending $3,500 to match a $7,000 custom rifle. Really? A good Savage top bolt release action…a new barrel whether take off or ordered can run around $300 from name brand to $200 from a hood gunsmith or $100 from a new rifle take off. You with me here? A Boyd’s Feather weight thumb hole stock runs about $175. A precision recoil lug runs $40 If the trigger is the accutrigger you’re good to go but if not a Basix trigger replacement (Fabulous trigger FYI) $125. A go gage $40 and if you want to check the no go just place a piece of scotch tape on the head of go gage and trim to fit the head. Works just like a no go gage. If you’ve a barrel vise and action wrench you’re set. If you already have a Savage top bolt release you’re ready to go. Throwing in a few bucks for bedding compound (NOTE!! Do not use Accuglass!! It’s a terrible bedding substance and shrinks when curing..bad!!!) and such $20 Okay..$500 for parts snd if a action is needed just go to a pawn shop like I use to do and picked up many Savage actions dirt cheap. $300. If you want a high quality barrel ho to Eabco. Excellent barrels $300 so adding up..Eabco barrel snd parts $700 and build. Here’s the thing. Boyd’s featherweight stocks are tough and strong. Thumbhole gives great handling. With very decent optics mounted “CORRECTLY “!! (I always use one piece HD scope mount bases from EGW snd their high quality rings) you’ve got a custom built rifle costing just for the rifle $700. $700! I bet two numbskulls years ago that my rebuilt Savage that I had around $1,200 in would out perform their $7,500 Gunwerks rifles. It did and they were arrogantly pissed off at me because I rubbed it in that they were ripped off. They were. Do what you want but if you’re looking to build a accurate hunting rifle that isn’t overly heavy and handles well and won’t make you having to eat Top Ramen for a couple of months of your life..go my route and smile at the shooting range.
