You can actually straighten barrels that are that far out. You might run out of scope adjustment with that much run-out.
About 8 months ago a buddy came by and had gotten a call for a last minute muzzle loader mule deer hunt in Colorado on private land he was leaving in 3 days. The story goes back 20+ years, when 12 of us ordered Encore muzzle loaders at the same time. He had shot his 3 times with pyrodex and after having to clean with hot water, exclaimed that he'd never shoot a muzzle loader again. We live in Texas, so here they are no advantage as you'd have to use them during regular rifle season. We never applied for muzzle loader tags, so they sat unused, he tried to give his away several times.
So he'd asked if I had powder and bullets and I did but I haven't had mine out in 20 years either. He takes them out and proceeds to sight in the factory iron sights (no scopes in Colorado). Sight bottomed out and all the way to the left and still shooting 8" high and 6" right at 100 yards. He tries mine and it's actually worse. I told him he was cockeyed and had to be him. Another buddies was still in box and he gets it and at least gets within 4" and calls it good. They actually killed 2 nice mule deer.
When they returned from hunt, I'd read where the QLA (quick load adapter) was sometimes a problem and put barrel in lathe and dialed in the muzzle. With muzzle indicated in, the chamber end had 0.240" of run-out. I cut the QLA off and re-crowned but didn't change the sight alignment. Put barrel back in lathe between centers and every 4", found high spot and wrote the run-out on barrel. Made a delrin adapter for hydraulic press and put barrel on V-blocks and proceeded to straighten both barrels. Got sights back in center of adjustment. I can only assume every barrel we got in that order was somehow fouled up.
I recalled that when I got mine, I originally mounted a 4-12x scope, ran out of windage and elevation. Put on a 3-9x, same thing. Finally tried a 2-7 and it had enough adjustment. Just didn't make the connection at the time.
I actually tried the log first and it actually helped but afraid it would distort the relatively thin barrels.
