This phenomenon is such a mystery to me. When I fire the Inceptor ARX .38 Special out of my J-frame (S&W 342PD) the projectile will hit the paper like buckshot at any given range, even from 5 yards. It does not happen every shot, but about 1/3 of the time. I fired this ammo through my 4" 686 and it fired fine, only in my J-frame does it happen.

I have asked people on Youtube about this, as I have a channel and posted a video on it, and their response is mostly that my gun must be out of time, but when I checked for timing it always seems to lockup before the hammer drops, I never have shaved lead or copper buildup on one side of the inner forcing cone, or anything of that nature. All other ammo seems to shoot fine. The only other thing I can think of is that the bore is tighter than normal, but I wouldn't know as I have never slugged the bore and don't know if I feel comfortable even doing that as I have never done it before.

Does anyone have any idea what could cause these ARX bullets to fragment before they even impact the target? Thanks in advance.

Interesting... Have you tried contacting the ammo manufacturer? They may have come across this phenomenon during testing.

I just now contacted them, and mentioned the particular J-frame in question, and mentioned that they were fine in the 686.

I have shot a lot of it out of the Ruger LCR9mm and the Smith 642 with no problems. It does sound like the bullet is coming in contact with the revolver. Get someone else to try the same ammo in another gun. I doubt very seriously it is the ammo.

Your gun can lock up and fire and still be out of time. Timing has to do with the cylinder and barrel being within a specific alignment when the cylinder locks. Your YouTube friends could be right. Because it's a frangible ...it seems as if it's hitting the forcing cone to one side causing some fragmentation before it's out of the barrel. I'd take it to a qualified gunsmith and have that checked.

I planned to take it into a gunsmith. I have however looked down the bore with a good light and have not noticed any alignment issues when it's locked up.

Have faith in your own, man on the ground observations. You got a gun with it's own taste in ammo and it doesn't like ARX. Shoot stuff it likes, you'll be happier together.

I have ARX for my Smith j-frame. Never saw anything other than the very light bullets shoot low, but I expected that.
