If the cantilever mounts didn't hold zero or were not that accurate I highly doubt they would sell that well. I live in a shotgun only state so pretty much everyone I know uses a shotgun of some sort. It's absolutely no different than a slug barrel with iron sights, except it has optics instead.

I don't know if you spend much time at gun range Paul.But I do, and every fall Iwould like to have a dollar for every guy who swears hit gun was zero'd when he put it up last year. And now is 5"-3' off. Could be the springs used in the scope. Could be after cleaning.
I would say alot of people on here live in slugbarrel only, so we are not that much different.
Paul, have you played around bedding a barreled action or putting pressure on front of a barrel and saw what happens? Next time you shoot, lay your barrel on your sand bags instead of your forearm and shoot long range. next time you shoot your rifles, put a credit card or thicker material between your barrel and forarm and see what happens.
