I've been reloading for 357 magnum and 45 ACP a while and just got a flat top Blackhawk 45 Colt/45 ACP. In looking at the load data, aiming for 900-1000 fps, it seems a lot of powders will do it with a variety of bullets. I reload to save money and for accuracy.
Why would someone load with a fairly large grain weight of slower powders like 2400 or 4227 when Unique or AA5 will get you in the same ballpark speed wise? What does 100-150 FPS difference do when deciding between tier 1 and tier 2 loads?
