RE: Shrinking groups of 300WM
For whatever it' s worth, my .300 Mag shot three (unnamed) bullets to about 3" groups and Swift A-Frames well inside an inch.......
Bullets that normally shoot well are core lokts, power points Hornady Innerloks, A-Frames, Bearclaws, ...and more that I haven' t tried yet.
These are all fine big game bullets...be patient and you' ll find a match for that rifle.....I like your 200 grain attitude.....great for a .300 mag!!!!!
