    I would think you're correct to assume that. It's entirely possible that in some cases the transition has little to no effect, probably depends on all kinds of things like the bullet size/weight/shape, spin rate, etc.

    So for the sake of argument, even though I realize this scenario is unlikely, if a .308 round transitions at 100 yards, and you have 1moa accuracy up to that point, maybe you'll have very small "deflection" (dunno the right word for it) that puts you at 2.1moa instead of 2.0 at 200 yards... 10.9moa at 1000 yards instead of 10.0, etc. Of course, it also depends on if the bullet "destabilized" as a result of the transition, if that's the case, it won't be linear - you could be 1.0moa at 100yds, 2.1moa at 200yds, 20moa at 300yds, 312moa at 500yds, back to down to 45moa at 1000yds....

    Note that I'm not speaking from any experience whatsoever

    Settle down, folks. The new "ghost gun" regulations probably don't do what you think they do.

      Yeah, thats what Im thinking also. However, i have seen some pretty popular guys shoot and say they've lost their bullet at X yards which means its not doable anymore. I been wanting a 1k+ range just so i can see if my 308 can be "lost".
