The ratings on Buffalobore ammo is stipulated at a certain barrel length. To estimate what you will get, look at the various velocities from different length barrels , then compare to your particular firearm. Sundles really knows his stuff.

That's still smokin fast for the weight. Good to see another bone test!

I've shot this ammo through my 90s vintage 6" gp100. Only put one through the chronograph was over 1600fps! Incredible

I don’t trust anyone who does not know the purpose of a bill on a hat

Great video man, those rounds look like a lot of fun to shoot. And I love that GP100, I hope to get one someday soon.

Like Jeff Quinn says about Buffalo Bore - "they don't cheat yee on powder".

I heard the Buffalo Bore .38 Outdoorsman hits like a .357 magnum and the 180 grain .357 magnum hits like a .44 magnum.

You're fortunate that you were handed a GP100 Ruger as a weapon in this video. Ruger is the best.Hands down!!

Buffalo bore uses a powder that is identical to Lil Gun (15.8 grains to be specific) and it is temperature sensitive, so depending on the ambient temps between your tests, that couldve been the difference.

Awesome Ruger GP100 4 inch in 357 Magnum !!!!!!!!!!!! Love me some revolvers !!!!!!!!!!!

Its what i carry into the kentucky woods. I dont go without it. My 6 in gp100 is my favorite out of all my handguns. Great video keep em coming. Happy 🦃🍗 day

Nice. I just bought a Henry 357 last night. I know that Buffalo Bore in 45 Colt will and I quote Henry Rollins here tear your mind out and burn your soul.

Could lose power if revolver has to much cylinder gap. Not saying that is the problem.

It's hard to beat Hardcast, time, and tested! At what point did you edit the clip when you loaded the first round and placed it at the 12 o'clock postion!?😂 There's many variables that affect velocity! Number one is barrel cylinder gap!👍 Good video, love to see these at work!✌️

A .22lr will shatter a smoked bone. Use a raw beef femur sometime.

Try the buffalo bore 180 gr jhp at 1500 fps.

BB has a pretty good reputation for publishing real velocities. You might be right about the age of the rounds affecting velocities.. or maybe it was just a bad batch.

Bad to the bone 🦴😂. Great revolver👍🏻

Yeah, the speeds they publish is forna 6" barrel. But they also have the speed for other barrel lengths and the particular revolver or rifle they use

I shot those loads in a model 60.....it really barked👍🇺🇸

Is buffalo bore ammo worth the money they charge for 20 rounds. I mean 20 rounds of 357 ammo for almost 50 dollars is quite expensive when I can purchase 50 rounds of 357 ammo from federal for 35 dollars

A head shot will drop anything in North or south America the 357magnum is a power house when loaded up to max.

Underwood rates a lot of their semi auto ammo in like a 3.4” barrel buffalo bore probably rates their ammo in no less than a 6” lol. For example, Underwood has a 135 grain .40 S&W rated by them at 1,400 fps. You would think this .357 magnum is way more powerful, but it’s barely more powerful from a 4” barrel. The .40 gets 610 foot pounds out of a 4”, this .357 magnum got 659. The .40 manages a solid 675 foot pounds out of a 4.9” barrel. And it’s also in saami spec. I shoot it out of my Glock 23 all the time. If this did hit 1,400 fps out of a 6” barrel it would be 783 foot pounds. I would imagine the .40 would hit in the 700’s as well out of a 6” if a 4.9” hits 675. Good video and still powerful result.

The 1375fps rating is a 4-inch S&W Mountain Gun. The only GP100 velocity (6-inch) listed on their site is a 125gr (1707 fps). Would be nice to see a Buffalo Bore product side-by-side comparison between a S&W L-Frame and GP100 both with the same barrel length.

Any one ever run this in a Rossi 92R?

Try a fresh bloody not baked out bone

645 pounds of energy at that velocity. Really pretty good.

Wow, if I hadn't swapped out my black ramp and red ramp front sights to finally upgrade to a fiberoptic, I would say I'm looking at my own revolver. Literally exact same...4" GP100 with the grip changed to the Hogue hardwood that happens to have almost the exact same color and grain pattern...I also have some Buffalo Bore ammo for it (except I have the 125 grain JHPs). Either way, that messed with my head big time when i saw that GP100. I thought for a second you broke in and stole mine lol. Stay safe brother

I've chronographed that ammo out of a 4 inch GP100 and have always seen 1350 fps or better. Out of my 6 inch GP100 I get 1400 to 1450 fps consistently. Maybe you had a bad batch?

My best gun and I have many

This is what I use but we only have black bears here in the north east I wouldn't trust it against a grizzly out west. But for black Bear I think it's ok.

its the shorter barrel my 4.2 shoots a bit slower but softer than a 6 or 7. less pressure time on the back end makes a little difference. the 150 jhp is the sweet spot for the 4.2 inch...imo

I might of missed it, but does it say on the box what barrel length was used to get their 1400fps claim?

So after my last comment about the Underwood .40 S&W 135 grain nosler that hits 610 foot pounds out of a 4” barrel, compared to this rounds 659 foot pounds, and 675 out of a 4.9” barrel, would you mind doing that in the bone test please? I could even send you like 3 or 4 rounds if you wanted.

How about buffalo bore 180 gr xtp bullets?

Maybe it's less than advertised because it's a 4 in ch barrel. What was the test gun buffalo bore used? What barrel length?

Looks a lot like an Elmer Keith load.

I just bought a GP100 4.20 inch barrel revolver (7 shooter), and it's my first firearm (still waiting for the background check to go through). So Buffalo Bore is the bullet brand for power? What factors do I consider to know the power and other characteristics of bullets?

Seem low velocity by other test. BB should be at 1400 fps.

Great job,, much appreciated ✌️

What grip is on that bad boy?

almost identical to hot 180gr 10mm

Buffalo Bore quotes 1375 fps from a 4” S&W L-frame Mountain gun. Out of a 5” Model 27, 1398 fps.

The bone should be raw. Cooking it makes it brittle.

I think their velocity is always off. As a matter of fact I actually emailed Buffalo to let them know that I was getting very low velocity readings and they told me it was the gun I was using... I thought a 4-in barrel was a 4-in barrel but still getting 150 ft per second If not lower than they're advertised velocity is a little misleading

I'm sure you realize advertised fps is from a 20 inch barrel coming out of a 4" barrel your not getting full powder burn that results in loss of velocity

Why in the world would you shoot a bone😂👍🇺🇸

Use it on a live animal. I'm so so tired to se those tests!!!!!!!.

Great video...ugly revolver 😂 ...get a 686+ smith

Hmmm...you're cute! Just sayin'...😁😁😁

3 rounds,to cheap for 5 LMAO! can't handle the 5 round of 180 grain huh? lol..I have two 640 J frames SW that I shoot 180 grain bear loads at the same time in right and left hand,it took me a wile to work up to that.fingerless gloves make it so much easier.
