I curently have a vanguard in 7-08, its has knox stock and basix trigger, it shoots fairly good with 120 gr, 3/4 inc to 1 1/4 inch 5 shot groups, I want to get an aftermarket barrel installed as I want to try my hand at shooting long distance, like 600 yds. What would you all suggest I set the barrel up for 120, 140 or 160 gr boolits.
Ridge ?
