Are we splitting hairs here...??...
....
Seriously, can you hold to 1/4" at 200 yards, or even 100 yards, under hunting conditions...??....
ABOUT 2" high at 100 with MANY similar centerfire rounds, such as .270, .280, 7mm08, .308, 30-06, 7mm mag, yada yada yada will get you ABOUT zero at 200 yards, give or take that 1/4" or so.... Might make a difference if you are shooting deer MICE, but not if you are shooting deer...
Let's make it even simpler, like Jack O'Connor did in a magazine article back in the mid 60s...
Take any one of those very similar cartridges ( like the ones I mentioned and about 20 others) and simply sight them DEAD ON at 25 yards...
Then check 'em atlonger ranges...Chances ARE they will be a couple inches high at 100, a little high at 200, close to dead on at 250 and a few inches low at 300... Just hold on center chest on a deer sized critter anywhere from point blank to 300 yards and squeeze the trigger..How complicated is that...??...
