I've been meaning to ask this question too. I use Federal EFMJ in my Keltec, but I've heard about this ammo. Does anybody know if it's comparable to the Expanding Full Metal Jacket where it is forced to expand due to a silicone ball, or is the Corbon different in some way?
The Pow R Ball loads are not like the Federal EFMJ's
Cor bon uses a polymer ball plugged into the cavity of a JHP. It has excellent penetration and will not get plugged up with heavy clothing as some JHP's will.
The only drawback is the bullet weights are on the light side. (The .45 ACP load is 165 grains and rated at +P pressures) It is a screamer though and has done quite well in ballistics testing.
So....with Corbon, the polymer ball is in front of the jacket, forcing expansion....the Federal load uses pressure against the polymer ball behind the jacket to force expansion 'around' the ball.......?
I just checked the Federal website and the EFMJ for 45acp is a 165 grain as well. It is going about 1140 fps and has about 475 foot-lbs. This is not quite as much in either respect as the Corbon load, which is a +P. Do you think the Corbon is a better load?
I was going to give them a try and when I went to look for a box the gun shop wanted $38 bucks for 20 rounds. I said thanks maybe later I don't know if you can get them cheaper I have not looked on the net for them but I have heard great reviews about them.
