Dongle,
I have A-bolts and BLR's.
I'll tell you how to fix it.
Go to Davids Tubbs website and purchase his 50 bullet break in system. If you don't re-load just ask someone to load them for you. Pickup up about 10 copper bullets for the final break in. (Many barrels are lapped and they really don't need be!) Lapping is a 2 way process and the bullet goes one way. His system will smooth it out in the right direction. It chould be dead accurate thereafter. If not, ask a good-smith why? A good one, is a shooter that has some competition and hunting experienceat least up to 600 yards.
Worst case, tell Browning, they'll make it right. And last choice have it rebarreled with a match grade barrel. Stills buy the David tubbs system for that barrel too.
Most everything you read on here about Browning is absolute ********.
And I have plenty of custom guns at $4,000 or better. Tough to beat my Brownings...
Best overall platform, dollar for dollar Browning. Why have they been around so long, Is John Browning still alive? FN sells 1/2 the guns made today.
2cents, and sensible...
Good Luck.
