What caliber is flatter?

[BULLBLASTER]

i would own a hunting rifle on how flat...sometimes turing turrets isnt a option and u better know your gun and drop rates on the fly...a flat shooting mag is worth its weight in gold out hunting..u can 0 at 250 and be good at to 400 with a mater of inches

agreed but the difference between the 7 mag and 300 mag is very small to 400 yards.

yeah..I am talking if someone were to buy a 7mm or a 338 and the difference out to 400 is considerable.  Really dont matter if you are turning turrets
