blr's
Sure you'll get it sorted out. You have to remember, when guys say levers aren't as accurate as bolts, we're not talking inches. Truth be known most of the accuracy difference is probably more due to barrel length than action. With the blr's locking lug system (if I'm not mistaken rated at 60,000lbs) it's likely more accurate than quite a few of the bolt action rifles.
Years ago I had a 300 Abolt. It was a tack driver at long distances, and yes it was more accurate at 450yds than my blr300, but we're not talking a big difference here. Keep in mind, I'm a hunter, not a dedicated target shooter. If I can get a consistant heart size group at the distance I plan on shooting, I'm good to go.
Expect excellence from that rifle. Soon as you get the problem sorted out, you'll have it.
Best of luck.
