My Rem. M30 in .35Rem. has a 1 in 16 twist but that was designed for 200 grain bullets. I am told it will probably be fine if I rechamber to .35Whelen and stay with 225 grains but I might have trouble at 250 grains. Remington also used 1 in 16" for their 700 Classic .35 some years back and also their pump Whelens.

But most guys starting out a build these days will go 1 in 12".

My problem lies in reconciling my gross habits with my net income.
