Been doing this for years...
another interesting observation..
about any big game SP bullet, with an MV of 2250 fps...
if zeroed 3.5 inches high at 100 yds, will be dead on at 200 yds and 3.5 inches low at about 230 to 240 yds....
apply this to the following..
a adult deer regardless of size and weight is 14 to 16 inches from backbone to breast bone..
cut that 'window of opportunity' in half.. say to 7 inches..
so if a hunter can hold steady, a simple 2250 fps MV, will be able to strike a deer, without any visual compensation on the rifle scope ( when zeroed 3.5 inches high at 100 yds) as long as the target is within 240 yds....
the cross hair set right on the ridge of the deer's back, can stretch this out to 300 yds or further..
since most deer are taken within 100 yds, and a bigger percentage are taken within 200 yds total, and a very small percent taken beyond that range...
a hunter with a load of 30 grains of IMR 4198, with a 150 grain bullet is more than armed and capable of taking a deer at 240 yds or anything inbetween..
only thing left to do, is to practice and pick the right bullet that will open up and penetrate deeply at that velocity...
at least here in Oregon with Blacktails.. one does not need a round with the velocity to kill an ELK at 500 yds, to take the average 75 to 110 lb blacktail at 100 yds or less...
