[QUOTE="Steve Shelp, post: 21533, member: 22"] Bob, The big question is what is your definition of accuracy? Are you judging by shooting groups until they start to open up, or just by the simple fact that someday you may not be able to hit a deer or elk with it? If your talking about average hunting accuracy (and use the std 1 MOA accuracy level) like the other poster above said, you'll be able to give it to your grandkids, though a new crown would/should help at some point in time. Now to go to the other end of the accuracy scale: "all out accuracy down to the last .001" of an inch" I own a 338 Lapau Improve for my 1,000yd Heavy gun clas rifle. I shot 1354 rounds through the Lilja SS barrel using anywhere from 91-98gr of powder for competition for 2 seasons. This is any number of sighters and then 10 shots for record. So anywhere from 13 to 18rds then cleaning using standard BR techniques. The throat burnt out .025" for those 1354 rds and had just started getting uneven contact with the lands, though it didn't show up on the target. It still shot very well. It's at Dave Tooley's shop right now to have another barrel put on it, but that isn't because the accuracy was gone, but because it wouldn't have made it through another match season and maintained the hign level of accuacy needed to compete. This barrel shot numerous groups in the .2XX" range at 100yds and even a couple in the ones using the 300gr MK. Talk about something that looks funny is a .338 (5) shot group that measures in the .1s. This is to give you a benchmark to go from. So depending on what your looking for it's going to be somewhere between say 1500/2000rds on up to whatever on the other end of the scale. And your shooting the std 338 Win Mag which is a little easier on barrels than my case so these numbers can be bumped up also even using the factory blued steel barrel. Hope it helps, Steve [/QUOTE]
