using these newer powders available, is it even possible to get a 140gr ( any) to a solid 2800fps, from a 22" barrel? And, if not, how close can one do it, safely of course. I'm think 62K Max pressure. I'm not talking about chasing the dragon, just wondering if it can be done? I know that a 1402800 is a solid killer i.e 7x57; 7mm/08, and similar rounds.
