Bart over time I have for the most part come to respect your knowledge of barrels and shooting . However ( I thought you deserved a fancy but)
A good shot can sight in a premium rifle using premium ammo with one round anyway
Com-on , one shot
. So you bore sight your new rifle how ever you please . Take one shot adjust your scope and your readdy to shoot the first round of the comp your in ? I've been real close in 2 shots and dead on with the 3rd confirming shot . Maybe one shot to be accurate enough to hunt dear or someting you got a nice size target to hit but to be dead on in one shot . I think that's one of those thing I would need to see to believe
If everybody has a problem with you and you have a problem with everybody .
It's not everybody that has the problem
