I just had a 'smith rebarrel my 22-250 with a Lilja heavy barrel. Even after careful break-in, it shot terribly (2" at 100 yds). I got out the Stoney Point gauge, and it shows 0.15" of bullet jump. My understanding is that 0.02-0.04" is more the norm, but the 'smith said there's nothing he can do for me.
I've already checked the usual suspects (free floated barrel, scope screws, ammo, etc.), and I think the culprit is excessively long bullet jump. For this I paid $700???
I returned the rifle to him tonight. He said he'd "look at it," but I didn't leave his shop with much of a warm and fuzzy feeling.
Am I getting hosed?
You may have got hosed. .15" is alot but depends on your situation. If your shooting factory ammo, could be the ammo is deep as most is. If your handloading and you cannot reach the rifleing, then his reamer is causing the issue.
Thats why when I have a gun rebarreled, I specify the freebore wanted with a certain type of bullet. My gunsmith can customize it with a two stage ream to my specifications.If he used a off the shelf clymer reamer, and you are using factory ammo, you might have to change ammo to find one without all the jump. There is no telling what off the shelf factory reamers are cutting.
I had a 300RUM rebarreled. Max COL I could load was 3.65", and my freebore was so long, you had to load out to 3.85" to hit the rifling. I was upset, but with a magnum like that, I found out, you really need some freebore, maybe not that much. But it still shot subMOA easily.
