I drooled over a Springfield Armory V16 Longlide about twenty years ago. I went home and researched the 45Super and decided I had to have it. I went back to buy it and it was gone. If you see something unusual that you like, at a good price, don't hemhaw around.

LOVE this! Glad someone is doing an in depth on factory .45 Super ammo. The community needs this info. New sub.

Because the .451” JHP bullets are designed to expand at standard .45 auto velocities, they over-expand and come apart at super velocities. The 135 grain solid copper FTM from Underwood would be my first choice for a factory self defense round. I recently converted my Glock 30 to .45 super, and I handload the 120 grain FTM Lehigh bullets to 1700 fps for 770 fpe. Recoil is about like a full power 10mm. I installed a KKM 4.7” barrel with a Wolff steel guide rod with 23 pound recoil spring.

+1 for the heavy hardcast 45 SUPER! Lots of guys have a 45 that can be a woods gun with a little help. I keep a couple of Glock conversions in 45 SUPER and the hard cast penetration is scary AND deep! Just the ticket for when you are not at the apex of the food chain out there

45acp and +p are great as is for a EDC round..45super is for the woods/4 legged threats. That said a Hardcast or solid copper penetrator type projectile. Whole new ballgame

The Super loading just increases the versatility, of the already versatile , 45 pistol. It can do anything that can realistically be expected of an auto loading pistol. Thanks for the video

My interest in .45 Super would be as a Backcountry gun. Some form of solid would be my choice

I’m most interested in 45 super as a hunting/woods carry option. I’m so impressed with the 230gr Punch out of my Colt Defender I have to force myself to carry my Commanders. My HK45 will take 45 Super at least in moderate use, but with the primer shortage I’ve yet to test the polygonal rifled bore with hard cast. I’d prefer a 1911 for a woods gun anyway (I seem to prefer a 1911 for everyday carry) so I’m looking forward to tests of 230-250 gr bullets. Keep up the good work 👍

I use the 45 Super in my Marlin Camp 45 carbine for hog and deer hunting inside 75 yards. Quite successful at that. My biggest hog weighed 300 lbs. The shot was broadside at 30 yards, squarely through two ribs. I recovered the textbook mushroom bullet inside the opposite hide. The hog trotted ten yards and dropped. On deer, the bullet went through, but they dropped inside ten yards as well. Getting more of this ammo, and 185 gr plus p for my Springfield 1911 Range officer.

nice shootin man!👍☝️🎯🔫⛳🎰

45 Super is fun, shoot standing steel side by side against a 10mm and you’ll appreciate how much more energy it has.

Use a flat based firing pin stop plate to hold the gun together slightly longer. Magnify the effect by increasing mainspring pressure, a combination barrel bushing/compensator will increase your shooting pleasure , and finally. ....... my country boy gunsmithing approach to solving the bullet performance works great ! Put a drop of candle wax into the hollowpoint , after it cools spin a flat bladed screwdriver into the wax to remove about half of the wax from the cavity. Pre-clogging that hollowpoint will increase penetration. Season to taste . My sr1911 with bbl.bushing /comp. , 22 lb. recoil spring, flat based stop plate, 28 lb mainspring, and high speed hammer fires standard .45acp- .45 Super with factory mags and 0 stoppages if any kind . The only down side is it won't go to slidelock on the last shot. ( the slide doesn't travel that far rearward) Underwood and Buffalo Bore 185s is what I shoot, and I like it a lot.

I use 185 grain HPs in my 45 AutoRim loaded up to 45 Super velocities, the Smith and Wesson 625 I own is modified by Clark for the 460 Rowland, but i find those loads more than I need. I have used them for about 7 years with good field results on deer sized game.

I’m excited to see that Underwood 45 Super 135gr Xtreme defender. 1500 fps, should have much lighter recoil as well.

250 grain Speer deep curl bullets at about 900 fps will give you everything your looking for, mild to shoot too.

Always love the .45 Super content!! Subscribed

EXCELLENT VIDEO. With the CORRECT projectile, ie Hornady XTP, Winchester Ranger bonded or nonbonded 230g, 255g Hardcast thus round penatrates deep and IS EXACTLY WHAT THE 45AUTO SHOULD BE!! The projectiles Underwood uses are Nosler bullets and they SUCK when pushed at these higher velocities. Doubletap makes excellent cartridges fir this round. They named them 450 SMC (short magnum cartridges). They use cut down 308 Winchester brass with small rifle primers. This is my preferred carry round. Compared to the 357 or 44mag the recoil IS VERY MANAGEABLE in MY OPINION. I stick with Buffalo Bore or Doubletap as my ammunition companies.

Perfect home defense

Interesting. Seems like one of the problems with 45 super is bullets being built for that speed. Seems like they are built for the normal 45 and this is just too fast for the bullet. Interesting point. Thanks for showing!!

I load my 45acp with 200grn hardcase SWC with CFE pistol powder and easily get 1100 FPS with 8.0 guns of powder , max load is 8.2 grains . Per the loading data.

I like the look of the underwood 230 asp super's... Would you be able to test that? Hope it's one of the loads you have on hand ;)

Great video! It is great to see content about the 45 Super. For those interested in the 45 Super, a Glock 21 with KKM or Lone Wolf barrel and 22# recoil spring is perfect. I've run mine like this for years and it handles both the Super and regular 45 ACP with perfect reliability. You MAY also need a 15% or 20% stronger mag spring from Wolff or AGP arms for the mag you load the 45 Super in.

Load up some 230gr xtp rounds in the super, I bet they will do well. Xtp generally has better controlled expansion at higher speeds.

Been waiting on this one

Would love to see some hard cast bullets tested. I think of the 45 Super as useful for big toothy critters that think you’re on the menu.

Interested keep the videos coming thank you sir

Enjoyable and informative video 👍

Be interesting to see a 230 grain hardcast at factory settings with under wood and the like my R1S is now set, ty, now gotta find the right round for the woods 👍

This is the same problem we've been dealing with in the 10mm Auto for decades; bullets are designed for traditional duty cartridges and pushing them 200 fps faster results in better paper ballistics but shitty bullet performance limits your ability to realize the full potential of the cartridge. A bullet that underpenetrates is of no use defensively or for hunting large game. I have found the heavier Hornady XTP offerings perform well at higher velocity than most common defensive handgun bullets. You may not get perfectly expanded flowers like the HST, but the XTP will give useful expansion with excellent penetration and weight retention. Penetration is important for good terminal effect. The 200 gr XTP load from Underwood has been a consistent performer on game from my Glock 20, and is my EDC load. I suggest you try a 230 gr XTP up around 1150 fps grom the .45 Super and see if that does a little better than this 185 gr, presumably Nosler, JHP. Nine inches is dismal and unacceptable for a defensive handgun load.

That's a lot of energy being dumped in 9 inches. The shock would have to be significant. If the velocity and weight is accurate, the hydrostatic shock would be high. Energy is transferred to the surrounding material. One of the lifelike torsos may reveal what the shock would do.

If you like that, you gotta try the 460 rowland! That will put that super to shame! Got 2 myself. A springfield xdm 4.6 " barrel with 460 rowland conversion and an aero tnw survival rifle carbine in 460 rowland .

It would be a good round to carry if you are worried about a violent confrontation in a crowd and don’t want any chance of a pass through. Gave almost comparable speed and energy to what I get with Buffalo bore 44mag 180grain swchp from my model 69

The Underwood 230s are the sweet spot. At least for the USP. Thanks for the great test!

The best option might be hard cast or something similar to a Lehigh defense extreme style bullet, since 45 revolver bullets most likely won't feed.

Great caliber for self defense with a 230 grain at 1100

Don’t know much about this round. Good test 👍

Double Tap's 450 SMC is an improved 45 Super that offers a little more speed and KE, and better penetration. Their hard cast offering is a great choice for outdoors big critter defense.

very interesting. 460 Rowland is stout too but different story.

Excellent , I would love this ammo and weapon for predator protection, especially bear defense.

Yep that projectile did not like those velocities. Lol definitely like to see the full copper round that can handle the velocity. I think underwood should consider bullets rated more for the velocities because this round just can handle it.

Hey I wish you would have shot the same load with a standard 45apc through the gel also

you should do side x side with regular 45 to compare gel test.

Drop in a "Phillips" head in that sucker. Good stuff 👍👍

MAC had the same gel results on his channel. He was getting about 7 inches of penetration.

An FMJ would be interesting to see or a bonded bullet.

Pretty big temp cavity!

Has the penetration of a 380, so what's not to like?

I run the 255gr .45 hardcast as a woods round.

🤘😎🤘

The fatness of the round looked good(wound cavity). I like the extra speed. I do not mind the regular 45 acp. But some worthy x power helps. With out a 16 inch barrel.😮😅

I wonder how the Hornandy's Critical Duty projectile would perform in this loading. Get deeper penetration and more expansion than usual?

I am guessing the faster the less penetration, so it did what was spected. And the pounds of force are nice!🔥💥💥🔥

Great video thanks for doing this. I'm not sure about HPs as I dont have experience with real targets, but I dont think the performance is what I need. I think HPs in part were for stopping a bullet to not over penetrate hitting innocent bystanders in an urban setting. To me for my use - which is mainly outdoors wild critter defense - I like hard cast lead with a flat point. I choose bullet weight, meplat and velocity based on what I think I need. I started loading 45 Super when I moved to Montana and lived in Grizzly country. I'm starting to think there must be a formula for the size of the meplat, the weight of the bullet and with velocity to equal depth of penetration. It was funny to see only 9 inches penetration with an HP and the old boring RN just bores right through. Somewhere in between the extremes is the perfect bullet for your needs. That said I never felt the 185gr was a 'sweet spot' for 45 but more of a compromise. I think you can get top performance from a 200gr and with CFE Pistol or Unique you can easily get beyond 10mm velocities...but its 45 :)

Whenever I run .45 Super out of my USP I also end up flinching and missing the dang target! I guess I need more training but I don't flinch with regular 45 ACP so I guess it's the heavier recoil....

I'll stick to my xtp 230 grain 👌

Rumors has it double tap is discontinuing the .450 smc unfortunately? good thing .45 super should be here to stay with that being said I’d love to see .450 smc on the channel and if you have any info on if it’s still going to be produced that would be great

So is this basically our 12mm?!?😂

i like .40 super

I'm watching this after your .45 GAP in ACP video; my apologies ahead of time You wouldn't happen to have a Hi-Point .45, some string, and vice, would you? 💥

Is that a ramped supported barrel I was just going to shoot the .45 super from my regular barrel with springs

The 230gr JHP will perform better, I imagine. In standard 45 ACP, the 185gr give decent expansion, but the 230gr essentially none. See Paul harrell’s video. That’s why at 45 super velocities the 185 over-expands, and I’d expect the 230gr to expand properly

I Cary the 185gr JHP 45 Super out of my FNX45

I think copper solids would be perfect projectiles for 45 super

Are glocks .45 super swappable?

So they are 45 magnum?

Please do a test of the extreme defense 135 grain 45 super 🤞

I bet a 185 gr hard cast would be nasty.

How is the .45 Super better than a .460 Roland? If you're going to beef up the .45 ACP, why not try for .44 Magnum velocities?

My favorite round

If there was ever a cartridge that needed to be bottlenecked it is 45 super. 45-40 would kick it.

Could you try it with denim?

Can 45 Super chamber in a 45 ACP pistol?

How does that compare to the.45 win mag ?

Aac start making 10mm, could you please review it? Hopefully it'll be a real 10mm, not .40

I think 12-18 inches is excessive. Also just my opinion but if a bullet exits the target that was lost energy and liability. I’d rather dump 700ftlbs into 9 inches than 400ftlbs into 12inches. Plus think of it this way if your target dept is only about 6inches, that means 45 super will get to dump 75% of total energy into that realistic size target so 525 ftlbs vs 45 acp 200ftobs 50% of its total energy into target.

Compare .40SW

The box of ammo says 1100 ft./s yet you got 1300. That’s crazy.!!!!!

I know that my HK USP 45 Tactical is rated for it, but I have been hesitant to try it. Anyone have experience shooting 45 Super through an HK USP 45?

Your analysis left out the fact that the bullet is not engineered for that velocity. I contend Underwood is ripping people off with these loads in that you get better performance with a 45+p that allows the projectiles to do what they were designed to do originally. I imagine that unless a manufacturer designs hollow points that are harder to open or peddle except at these higher velocities these rds are a waste of $. . Pretty extravagant endeavor for a semi wildcat rd. I’m suffering with buyers remorse for buying their 185 grain 460 Rowland hollow points that flatten even sooner ( closer to 1500 fps). On the other hand the Hardcast or Lehigh penetrators are a different matter and those are my first choice for a hunting sidearm. I’m sure that the hollow points would still be a bad day for any 2 legged varmint but kinda pointless except for penetration concerns.

Ok, put a Carhartt jacket, and two other inner layers, what is it going to do. I realize that you don't have the funds to test every situation. Hmm, not sure if it's worth it.

Still no match for the 185gr at 1575fps .460 Rowland

At 1000fps that bullet would perform ok.

2:07 is 1304 the time it took to take the shot or the speed. JK

Wrong bullet choice for sure

Totally underwoods fault, test your products

Also, JHP in .45 super is pointless. Absolutely wasted effort. .45 super is best as hard cast.

I almost fell asleep between your shots. Fix yourself. Learn to shoot fast and accurate. Wasting time between shots does nothing for accuracy or defense except failure. Otherwise, nice test. Thank you.

Say a 120-130 grain hardcast with a wide meplat at max 45 super velocities would cause a nice big shock wave, not need to rely on expansion, and dump all it energy very fast. Probably the best self defense system for 2 legged critters using 45 super. Underwood uses their copper spiral flutes but woukd prefer just a flat big ol meplat front to the round.

That's a nosler bullet Underwood needs to quit using nosler bullets with 45 Soopers that's all there is to it that's why you never see a nosler bullet in a 10 mm at least I haven't why you're getting that minimal penetration they need to start using a different bullet with the 45 super

I don't consider 45 super significant recoil. I don't even consider 44 magnum significant recoil.
