which powder

[onesonek]

hi,,,i recently came across a savage 270 winchester,22" barrel,1 in 10 twist,,,i'll be shooting 140 grain noslers bt's out of it for my first bullet try,,,i have always understood a shorter barrel needs a faster burning powder than a longer one,although 2" would probably decrease my muzzle velocity by 100 fps,,,my powder cabinet is full of like 8 or 10 different powders 4 of which are in noslers book,,,i don't need loads just a start off powder,,,the powders that i have in the book are,,,RL-15,,,IMR 4350,,,IMR-4831,,,and H 4831sc,,,thanks :grin: :grin: :grin:

In on this one abit late, but I agree with the H4831 and RL 22 suggestings.
I too use to think going with the faster powders with shorter barrels made logical sense, but,,,,.
When I really got back into loading for my specialty pistols, with barrels ranging from 15 to 17" in length, I found that isn't always the case. The slower powders gave me more muzzle blast, but often the slow powders gave me the best accuracy and velocity.
