Hello Snipers, I would like to develop a softer shooting .223 round for an AR Pistol. I'm looking for something with less recoil and blast than traditional loads. I'll be shooting it out of a 9.5" barrel with a 1:8 twist. This is meant to be a self-defense load for 50 yards and in. I will likely use CFE 223 or IMR 4895 unless you have a better suggestion. My main question is should I go with a heavy bullet like 90 grains or something light such as 55 grains? I will probably try to push it in the 1500-2000 fps range. I am not trying to make it sub-sonic. Let me know your thoughts.
