The +P data I have for bullseye tops out at 3.8gr for a claimed 954fps which would be less than the standard pressure max for HS6.
Would 4.3gr be +P+? I want these to be safe in my alloy framed 642.
I'm not sure what the make up of the bullest I'm using are. I bought them at a local gun store and they are made by a local company I assume.
