Friend dug out a Rem 700 in 6x45 that he's had for years and hasn't shot it yet. He 'finds' more guns in his collection that he's forgot he had than you can believe. Anyway, would any of you guys with 6x45 experience and 70-80 grain flat base bullets share powders, velocities and charge weights you had success with? Research I ve done to this point mentions H335, H322, H4895 and H4198 as all good candidates. He has all these powders and more. Back in the day the 6x45 was one of the good ones for short range benchrest accuracy. ( The PPC and BR case took care of that) Thanks for any suggestions!
