How many Barrels have you needed to change till you got it right? I have a stock Barrel on a Remington 700 .308 that just won't do the deed. I have tried till I nearly cried, while the other guys are ringing the plate at 500 and 600 yards I can't do a thing at 400. So this winter its going into the shop, it has a hot date with a new Broughton Barrel. I am sure some might think there is a cant in this scope like the other, no thats not it. we had this action/scope level to the a point of going a bit over board. We have a tool and die shop and most work is .00001, I built a .223,,, 4 years back and I was so worried I just made a mess of the first try but I did good!
