Ballistic gelatin test results - website

.410 slug and new .38 Special posted

nero,

I'd love to see some results using .32 H&R Magnum. I've search far and wide and haven't been able to find any ballistic gelatin results for that cartridge.

Have you heard of the .32NAA cartridge? It is a .380ACP case necked down to accept 0.311" (32 caliber) bullets and is the ballistic twin of the .32H&R Magnum and can be fired in any .380ACP handgun.

I have been developing handload data for this cartridge and will soon publish gelatin results with the Cor-Bon factory 60 grain JHP and a handloaded JHP in another bullet weight.

Thank you.

Thanks. I look forward to seeing your results.

Wonderful website. I have just one request. Could you chage the text colors so that its not black text on a dark blue background. Its a little hard to read. Might I suggest yellow text on the background you have, or changing it to a lighter color, perhaps a sky blue?

I agree! Great website but the black text on the dark blue is very difficult to see.

Great site! .357 mag coming anytime soon?

Yes, .357 Magnum will be one of the calibers on the board to be tested, as well as the .44 Special and .44 Magnum. Look for Cor-Bon .32ACP, .380ACP, and .45ACP to be tested in the shorter term, however.

I did test one of Federals Personal Defense 130 grain .357 Magnum bullets in ballistic gelatin. The one shot fragmented during the entrance phase, the intact part expanded to 0.505" and the deepest penetration was ~ 12.5". The fragments did an odd thing in this case - they pretty much traveled along at the periphery of the bullet, cutting tissue that was displaced by the temporary cavity. I have not before or since seen this happen in gelatin but the end result was to cut a hole of almost uniform diameter of 0.75" from the entrance to the end of the track. Very unique and I would like to see if this is typical of .357 Magnum revolvers.

Thank you.

I only have a couple of questions. Where are you located and when can I come visit to join in on the festivities. I'll even bring my own guns.

Cool site!

Excellent site!

Looks like a fun (and expensive!) hobby!

I'll add another request for .357 Magnum in a variety of bullets. I'd also like to request some tests of the CCI Blazer Brass as it's cheap and plentiful and I've often wondered what it's performance would be. I know the defense-specific ammo is very popular and interesting but I'm curious as to how the cheapo Blazer hollowpoints and fmj as well as white box Winchester performs in comparison to the latest and greatest.

I really appreciate the variety of loads you've tested so far though. There's something for everyone in there, and who'd have thought the .410 slug would mostly turn to powder in gelatin? The 12 guage stuff was nice and dramatic as well.


Thanks for putting all that effort into this for no pay, it makes for a great read!

Update - Short barreled .45ACP posted

Thank you.

I will be posting shortly how to put the gelatin results on my site to work for you, without needing to have test equipment, etc.

The performance of that particular slug was a surprise to me. I have never had a piece of block come back and hit me, but the destruction to the block during the initial inch of penetration was so great, that a 1"x1"x1" approx, chunk flew back and hit me in the face. I suspect that another slug, one with a jacket or traveling at a more modest velocity would not break apart, like this one did.

Just by the way, I'd send you some of the el cheapo rounds if you don't want to bother buying a box (you're apparently spending a good bit of money on ammo even if some of the stuff is borrowed). I have some 55gr white box 5.56 and .223, and Blazer Brass .357 158gr JHP and .38sp FMJ.

PM me if you want some samples to use.

Update - 'Testing your bullets'

Just posted a guide to correlating your guns performance with the performance of the same load in ballistic gelatin. It should appear with the introduction page at http://www.brassfetcher.com .

Thank you.

gp911,

Thank you for the offer. Have you had a chance to read the text that I put up on the website? I think that might explain some things, at the very least the instructions for water testing bullets are listed there.

The 5.56x45mm ammo that you mentioned might need two OJ jugs, one directly in front of the other, to see if the bullet will fragment or expand. If you get an expanded bullet close to 0.40" diameter, all should be well. I would guess though that it breaks up like US military ball ammo.

Try out the 158 gr HP in water, I've got results posted for a 158 gr LHP from a .38 Special, it may be relevant to you.
