Most of us building them are using tradidtional rifle actions with locking lugs on the bolts. I think that's where the primary confusion about charges differences comes in.Welcome Scott! I had purchased a 700ML to do a conversion on and then a Savage showed up on here. I sold the 700 but have yet to get the Savage out. Are the REM loads really in the 75-80 grain range? Savage recommends 44 grains of 5744 as a starting point. Most of not all of my ML shots are within a 100 yards but I’m thinking like a traditionalist. I’ve had opportunities to go deeper but didn’t have the gun to do it.
