i have been shooting a win laredo in 7mmrem mag. it shoots ok with the light bullets, but not very good with the heavy bullets. i am thinking about putting a new barrel, and getting the action trued. is this a good route to go, to start in long range? i know a remington action would probably be better, but i have a winchester now. would you stay with the 7mm, or go to another caliber. sorry for the long post, and thanks in advance
