Home Forums Hunting & Shooting Ask The Gunwriters Are These The EXACT Same Powders?

I have used W-760 data a number of time with H-414 powder. I always start low though and work up wit one round going from several grails under to max W-760 data. I've heard the same about them being the same but I do pressure test before getting crazy! Has always worked for me. Didn't know AA-2700 was also the same but I'd still pressure test it first.
