10mm gel tests
« on: November 08, 2012, 08:34:21 AM »
I've tested several 10mm loads in homemade ballistic gelatin. While my gelatin is not 250A bloom photographer's gelatin, it is still actual gelatin, not synthetic material and it is calibrated with a .177 cal BB @600 fps +/- 10 fps.  I also have compared the performance of well documented loads such as factory Speer Gold Dot .40 S&W and Prvi Partisan 75 gr BTHP. The results are almost identical (within expected statistical variation) to the published results so I feel confident that these results, while not scientific, are at least indicative of the general performance ability of the loads tested and should be within a few inches of what a professional lab might get.

Chopinbloc?

 So many screen names  :D


I would just keep all videos right here and they can sticky it. I sent you a ton of work and look forward to the BCSP's!

LOL. I'm active on a few forums. That ammo will definitely keep me busy for a while. Thanks again.

Should be able to test the Corbon 180 gr bonded core soft point on Saturday if all goes well. Might even be able to squeeze in a 200 gr XTP retest.

Any clue what bullet that Razorback is or the Precision Cartridge?

I'm about 99% sure that the Razorback is a Montana Gold bullet. Here's a pic of the Razorback (right) next to a Buffalo Bore (left). Both use Starline brass but the Razorback is nickel plated. I'm interested to see what it does in gel but I predict it fragment at least as much as the 180 gr BB/MT Gold and penetrate right at about the 12" mark.




You sent me two loads from Precision. One is definitely a Golden saber. I really have no idea what the other Precision bullet is.

Good picture! Okay that is a Montana Gold like BB but it's so much more Gold  ;D


     The two Precisions are different Companies. The Golden Saber is a 180gr from Precision Cartridge. When you mentioned GS that's what I thought it was. The other is a 180gr from Precision One Ammo 180gr which I think is a Zero. This is good because to the best of my knowledge the 10mm GS has never been tested in Gel. I think the same is true for the Zero bullets which are very similar to an XTP.

Yup. That's what finger oils do to unprotected metal in a couple months.

I'm pretty interested in the GS, too. Frankly, I'm interested in everything. As a poster on another forum says: "Shooting stuff is fun."

Well Crapsicles. Chopinbloc said the BCSP's from Cor-Bon passed through 28" of Gel. The 220's will need a mile  :o

His Chronograph readings out of a 4.5" barrel Witness:

Shot #1: 1,228 fps
Shot #2: 1,198 fps
Shot #3: 1,212 fps
Shot #4: 1,194 fps

My previous test: 10mm Corbon 180gr BCSP 1300 FPS (Match 4.75") 1202, 1188, 1192. Average = 1194 FPS/ 569.68 LBS

 You and I got close on the Chrony. Oddly Cor-Bon's 1300 FPS rating out of a G20 4.6" barrel is BS and they don't care. This is the third confirmed low performance at $40/20  :o It's a unique to the 10mm bullet for hunting but unless it does something different hitting a bone just load up on TMJ/FMJ and go! Way too much for a HD round!

Double Tap and Buffalo Bore are also putting out ammo that is below claims. I suspect that what happens is they load badass, hot ammo for a while, then some retard(s) blows their gun up and complains and they start toning down the loads but don't bother to change the printing on the box. DT and BB both *used* to make ammo that met the claim. It might be the same story with CORBON.

Frankly, I'm not a big fan of them anyway. They are the same company as Glaser and all their products just seem a little gimmicky. I do want to load up some of those Winchester soft points you told me about. The jacket is scored as though Winchester expects the bullet to expand somewhat. Maybe they used softer lead.

Good you have denim. This is what I got from Atomic:

Make certain to have the people doing the Gel testing place 4 layers of cotton denim over the Gel block. Testing bare gel is a poor test for expansion and penetration and many bullets, at least in other calibers fail to expand reliably after 4 layers of denim. This time of year many people across the country have on a few layers or a couple of thick layers.

Roger that. Four layers of denim is an IWBA protocol and there are a lot of bullets that don't do too well through it. Newer designs handle thick clothing much better. Obviously it wouldn't have made any difference with a soft point but I think it's a good idea to maintain consistency as much as I can.
