[QUOTE="Mike Matteson, post: 2585252, member: 101791"] From what I have been reading. That barrel erosion of 0.004 to 0.007 per 100 rounds. This in match type precision rifle competitions. They talk about increasing powder or increasing or moving the bullet forward. Now I have a rifle just completed (6mm/280AI) with only a couple of round put through it. The barrel is Bartlein Metal grade 400MODBB Heavy in 30" @ 7-1 twist rate. I continue to read about burnout with barrels. So that's why I got a long barrel. So I can have it cut back at both ends as needed. Bartlein said that the barrel should go twice as long as a normal barrel would. We'll see. I also got a 2nd barrel at the same time, but have done anything with it. Some say that that barrel will burn out in 500 round or less. I don't think so, but I been proven wrong before. What the velocity is going to be I don't have clue yet. I am thinking that my go to bullets are going to be Hammer Hunter 100gr. I have others in different weight, mostly heaver to 115gr. My go to powder is generally H4350, and H4831. I have both on hand. Still don't have H1000 or Varget yet. The cleaning will be done by Bartlein standards. So I will watching and will keep you posted. So I will have records from the get go. I just have to get back to Montana to load and shot the rifle. I don't have a bore scope yet but will have one here shortly, and before I start.
