Beyond 400yds is a good metric in the hunting world.
Right about there is where, even a lot of the flat shooting rifles, have dropped or are dropping below MPBR.
Yep
Very few will get to 350 with a 6" target size. More with 8" or greater. A 6.5mm 142g bullet with a B.C. of .625 and 3050fps at the muzzle has a 313 yard MPBR at 7000 feet altitude for a 6" target, 352 yards for an 8" target. A 10" target only gets to 386 yards MPBR, but now you're talking about +5" above line of sight. I prefer 3" max, hence my preference for 6" target sizes for MPBR zeros.

No, I'm not a Ruger bigot - just an unabashed fan of their revolvers, M77's and #1's.
