Welcome to 24hr Campfire,home of the 264WM cult.My 1in9 barrel works with 140 SSTs,but a faster twist would shoot the heavier Woodlieghs. My gunsmith opened the throat to a normal length on the barrel.I haven't had any of the spikeyness that I had with the orginal barrel.This would be very good thing if you use the ADI powder we call H-1000,in the stardard chambering,it can get ragged at +60,000psi. Hogdgson lists it max psi lower than H-4831,a give away.Retumbo has worked for some as well,just not me.
