Yes John built mine off a win model 70 300 wsm action 1:7 twist. The 143 is using 57 gr RL 26 and the 100 ttsx using 58 gr h4350
Recoil is a joke. I watched a doe flop thru scope at 279 yds last Friday. Touch the trigger with the 100ttsx and they gone
How many rounds u got on it now? I've had a 22-284 and a 6-284 both lost accuracy after 1k which is what I expected but damn barrels are expensive......
