[QUOTE="highdrum, post: 2625040, member: 13732"] I have 3, 1 has been good, 2 others have shown pressure way early, bolt lift, swipe, talked to manufacturer, never even offered to take a look at them. I'll never touch one again. I polished the bolt face, reduced ejector spring tension, and it helped some, but still a 60° lift action requires a lot more mechanical force to extract cases than a 90°, lift will always show up earlier with a 60° 3 lug. My 338 rum is on helios serial number 0007 and it's been great, however the problematic ones have been much more recent production. Personally 90° action with 1.125" tenon is all I'd run, ensure the barrel has at least 3" of shank at 1.250 diameter. [/QUOTE]
