44 magnum vs 10mm heavy bone hard cast test

[beeenbag]

So since being on this forum for many years, a common thread is the bear defense thread and 10mm is always in the discussion, as well as many others. I did this video for my youtube channel, it has not posted there yet so until it does, this is the only link to view it.

I know this isn't scientific or conclusive in any way, I just thought this may shed some insight onto how non expanding hard casts perform from the 44 and the 10mm through some heavy bone.

Also give THR a little shout out in it. Hope you enjoy.

Cool video. I’m surprised that neither one made it all the way through. I thought they both would make it to the gel.

I think if the 44 didn't deflect, it would have made it to the gel. Just my opinion of course, and I didn't have the material to try again.

Thanks for posting.

Very nice! I appreciate you fellas that take the time and initiative to put these videos together for the rest of us.

Interesting video. Thanks!

The compression (seen in the slow motion footage) between the various pieces of bone is likely a big part of the reason neither made it through to the gel block. That's just a big energy sink to overcome. But both made it through more than one piece of bone, and that's probably more than would be needed to hit something vital inside a bear. So I'd say both were successful.

From an old fart - COOL!

I ran some of those Underwood 305gr .44 Mags over my Labradar using 3 different barrel lengths - also 305 gr Buffalo Bore:

Buffalo Bore, 305 LBT LFN HC rated 1,325 fps
Underwood, 305 LFNGC Plated (HiTech?) rated 1,325 fps

LabRadar muzzle velocity at 33 deg F
S&W M69 2.75" ===> BB 1,195 fps ===> Under 1,147fps
S&W M69 4.25" ===> BB 1,276 fps ===> Under 1,248 fps
Ruger SRH 7.5" ===> BB 1,395 fps ===> Under 1,315 fps

Thanks for doing the test, just another example of they probably penetrate similarly, but the energy difference cannot be refuted.

I'd be curious how the Underwood 150gr Xtreme Penetrators would perform in the 10mm. They are clipping along at 1425fps.

Thanks for posting as well as taking your time and effort to make a thought provoking video.

I enjoyed and "liked" your video, beeenbag. The devastation of the 44RM was astounding. The 10mm still seems to get the job done.

Interesting.
44 Mag is more powerful, but 16 chances (Glock 20) to hit something versus 6 (revolver)
Bear can move 30 MPH, hitting, or trying to make good hits on a moving target makes additional rounds seem advantageous.

Thanks for taking the time to do the test

I am not a big video fan but I enjoyed this one. Not much hot air and blather like so many although I did begin wishing you would just put your hands in your pockets before the end.

Something that was surprising to me was how explosive the destruction from the 44 mag was. I didn't expect that from a hard cast bullet.

I’m a nervous talker so I use my hands a lot, plus I wasn’t putting my pork hock, 3 month old deer leg, beef rib covered hands anywhere near my pockets lol.

funny fact, I actually cut my finger on the 10mm bullet in this video, bout took me out. Ended up on antibiotics twice because of cellulitis in my finger from a tiny scrape.

I didn't sense any nerves, it was easy to watch and informative.

Crazy about the cut and antibiotics, glad you are ok.

Sorry to hear about the infection.
Love the video! Enjoyed watching the comparison

I agree .. also quicker followup shots .. being less recoil .

The problem is, in a real charge you’re not going to get 6 or 16 shots off. They’re rather rapid close range affairs.

Exactly what I thought.
Yes an easier to control round has an advantage in follow up shots, but an animal going 30 mph will close a lot of space very quickly.

 

[MachIVshooter]

If I were gonna encumber myself with a large revolver, it would be a .454 Casull, not a .44 mag.

Due to capcity, controllability, size, weight and performance, if I were to choose from all of my starts-with-a-four magnum pistols for back country big critter defense, it'd probably be the LAR Grizzly .45 win mag. 8 rounds of .44 mag equivalent with faster follow up shots in a package that's easier to carry. The 3" 629 is shorter, but that round suffers badly in such short barrels. Even 4" really ain't enough. I haven't played with heavy hard casts in the .45 win mag yet, but it exceeds 1,600 FPS with 230 gr loads from the 6" barrel. It's a powerhouse for sure

That sucks, but not surprising. Gonna be all kinds of nasty bacteria in decaying meat.

Dunno about you all but after humping a 1006 10MM on my hip along with backpack, rifle, binoculars up and down mountains in elk county around 9,000 feet, any small weight reduction is a blessing. One reason why I shed the 1006 and went to the Glock 20.

Yup. G20 fits the bill nice for humping up and down elevation while hunting/backpacking.

 

[WisBorn]

@BreechFace and @Lennyjoe if switching to the Glock 20 for weight reduction is a good choice. Would going to a Glock 29 be even better?

I draw the line at the G20 due to grip length (I sometimes carry my G40mos, dependent on the terrain), I don't want to fumble with fingers off the grip. But if one doesn't have a problem with the length of grip then, yeah the weight reduction would be nice.

G20 = 30.69oz
G29 = 26.81oz.

It seems there some hunters who use the G29 and put in a 4-5" aftermarket barrel to get the velocities they are looking for, whether necessary or not is another matter. I always thought to myself, why when a G20 is within 4oz. of the stock G29 and with adding that aftermarket barrel you are probably within 2oz or less at that point with a shorter sight radius.

 

[BreechFace]

@WisBorn If you are considering a G20 there is also the G20SF model. SF = Short Frame

The only difference is the back of the grip area on the SF model has a reduced circumference for smaller hands. But one loses the grip panel options. I have longer fingers so the standard model doesn't bother me, but the SF version may make a difference for some. I don't feel there is much difference.
