    Zeroing is only to account for ballistic drop (wind and other environmentals too) and essentially a perfectly straight barrel. So that from 100-200 you only have a vertical or minimal wind shift left right for such variables.

    Again, just my .02
    Can you expound on this concept of bullets "zinging"? Do I understand you to mean that the bullets curve through the trajectory because they curved through the barrel?

    zinging is slang for pulling to one side. Just as ive heard people using the golf term slicing.

    You hear this stuff at ranges all over the country. Really not uncommon.
    From TOS ... "buy the shit out of that thing, all the mil spec is just nonsense."

    I've spent 40 years on ranges, I don't remember hearing the word "zinging". I'm trying to get a definition of it. You have introduced a new concept, that of the bullet "pulling to one side". I've never heard of that either. Is that kind of like when your truck needs a front end alignment and it pulls to the left or right? Maybe I've never heard of it because I don't shoot at ranges "all over the country" like you. How is it you are able to do that? Are you a full time competitor, travel from match to match? A full time instructor giving classes all over the country? You on a factory team, something like that?

    Re: Bent Barrel

    Once the bullet leaves the barrel it will have no lateral deflection other than a slight amount of spin drift.

    No matter how bent a barrel is, it won't cause the projectile to have a laterally arced trajectory.

    What's the facetious emoticon

    To answer the question though, yes I was being facetious.

    That bullet may have hit a large bug in flight. The Brits did a study of bullets striking rain drops and concluded they are significantly deflected when it occurs. I was firing a 375 RUM at 200 yards and saw a very large bug cross my line of sight right at the moment I fired. I mused that it would be amusing if I hit the bug. Sure as shit, when I got down to look at the target there was bug guts all over it. I actually hit a bug on the wing with a 357 RUM from offhand at 200 yards. I couldn't really tell though if the impact deflected the bullet. I meant to take the target down and save it but got distracted and left it.

    So I think we can safely say, zinging, pulling and slicing notwithstanding that if you shot a gun like this:



    on a range you wouldn't have to worry about the bullet going in a full circle and hitting you right up side the head.

    This ratio would be accurate *if* the barrel was deflected at the breech, but the OP states the barrel appears to be bent near the gas block. As such, the deflection would be considerably smaller.

    Then again, all of this presumes the front and rear sights are in the same plane as the straight portion of the bore--which, since the rear sight is cranked all the way to one side, they clearly aren't.
