I don’t have any 6mm and want to build one for deer hunting. Need recommendations for which 6mm to go with. Want a 22” plus brake on the barrel. Needs to feed good and shoot a 105-115 at 3000 fps minimum. Will a Dasher do this? Also thought of going 6x47 or going with the new 6SST from Rich Sherman. The 6SST will run up to 3300-3500 fps. Will be used to shoot/practice on steel out to 700 yds. But main use will be hunting Whitetails. Looking for low recoil, accurate and decent barrel life.
