Long time reader first time poster. I just have to say how much I like to read this site. Lots of great question and all the responces are good and well thought out. I've been shooting a Browning Abolt in 338wm for the past year. The rifle is all stock with a Boss muzzle brake. Well I cannot get it to shoot worth a darn. On day it's better than an inch the next its throwing them to the moon. I've reloaded every bullet wt. with a many powder and primer combos. I would love to accurize it. Any idea where to start? Is a new barrel in a new chamber(since I'm not sure how much more load developement with a 338wm I can take)a good idea? Are the Abolts worth building a good 600yr rifle out of? I've shot service rifle comp for a few year and am confident with a 600yr shot and open sites at the range but would love to break into long range hunting.
