Just picked up my Thompson Machine ISIS-2 and reading through the package insert sheet there is an Installation and Use section that says:
"The Isis-2 should only be used with factory-loaded non +p FMJ ammunition. DO NOT FIRE HOLLOW POINT AMMUNITION IN YOUR ISIS-2! We recommend Alabama Ammo Special-K or similar loadings."
First I've heard of not using JHP, not an issue as with the volume I shoot, I buy what's cheapest and I've never seen JHP for less than FMJ, and +p makes no sense if you are wanting to be quiet and hopefully subsonic. I've also never heard of "Alabama Ammo".
Maybe JHP has a lot of yaw on exiting the barrel? Some stop action shots I've seen of bullets leaving the barrel have left me wondering how baffle trikes don't happen.
