[QUOTE="Austin, post: 29896, member: 1956"] Len: Couple more questions for ya: 1) I read that you are planning on using a 34" bbl in this project, but what twist rate are you going to use? 2) Will you be using a muzzle brake? 3) What kind of scale were you using to weigh charges when you were getting vertical stringing at 1k yds? I have had the exact same problem in the past and I switched to a digital scale which made the problem all but disappear. 4) On your switch bbl rifle, what kind of problems (if any) have you noticed when it comes to accuracy? I was considering making this 7/.338 a switch bbl so I can shoot .338 Lapua Mag as well and I am concerned about accuracy. Seems like it would throw the blueprint and true centerline of the action off when you switched bbl's, but, hopefully I am wrong in assuming such and it won't cause me a problem. I'm very interested in your datum here as I would REALLY like to see just how far the 7mm envelope can truly be pushed. TH [/QUOTE]
