Great site with tons of reloading data.
I've been using Reloader 15 for my 303 scout rifle with excellant results.
I just got some of Sierra's 174gr Matchkings and intend to do some load development very soon.
Anyone here have any suggestions for a good whitetail hunting load?
I've been getting MOA with 42.5 gr. of RE15, WW primers, Yugoslavian brass and 185gr. .313 diameter bullets pulled from 7.65 Argentine ammo.
Not too bad for a $20 surplus 2 groove barrel!
