[QUOTE="fmuguira, post: 1732958, member: 27974"] I had a 300 WM that loved 165, 180 and 200 Accubonds. 165 and 180 BTs too. Shot barrel out and tried same loads as before in my new barrel... no dice!! After fighting through powders, primers, etc finally decided to try a group with some Sierra 180 GK and Prohuntersvwith my old charge of 75 grs of R22. Bingo!! Both shot 3 shot groups right at .500-.600. Also my OAL with the GK was 3.490 and 3.510 with the Prohunters; both .015-.020 off the lands. That's where I ve most always had good luck with multiple calibers and cup and core Bullets. I ve been loading over 50 years so have some trigger time. Lastly, both the Sierras fit and function comfortably in my R700 magazine. Usually most guns will group a number of reasonable burn rate powders well; I ve found bullets to typically be more temperamental in some guns. Good luck [/QUOTE]
