So what ur saying is that it was really stupid of me to order a custom barrel that switches from RH twist to LH twist midway down the barrel to counteract the torque I am so worried about.
I suspect that it's not much worse than my sub 9 pound (as shot from the bench), no brake, .375 AI with 250's @ 3130 mv! Yet, can still manage sub 2", 3 shot groups at 300 yards.....you just have to hold on tight! memtb
I'm not sure never shot one, but I know the 338WM no break i have is a breeze compared to a 300wsm and 210-215's.
The 300wsm i just loaded for shot great for a hunting gun 1.75" at 475
