First of all, if your going to post back and tell me to "just get a .22 conversion, it's the same thing", do me a favor and stick your tongue in a pencil sharpener. It's about as intelligent as comparing a 40 grain lead .22 to a 80+ grain jacketed bullet. I do already own a .22 conversion.....
Ok, I will be shooting these out of an AR-15. Yes, I know they will not cycle and I am ok with that, I have a .300 Whisper upper for that. I am looking for data to use some kind of fast powder to safely launch a very heavy .223 bullet downrange at around 1050 FPS. The two pistol powders I keep on hand are H-110 and Bullesey - if I could use either of those, that would be awesome, but I don't mind going out and buying what I need.
