Truer words were never spoken.Far too many people buy a rifle chambered in a cartridge that has long range potential,then sight it in at 100 yards and figure that they are now ready for long range shots at game.In reality it takes a great deal of shooting to learn your cartridges trajectory and even more to develop and maintain the shooting skills necessary to accurately place bullet at distances out to500 yards.In fact far more shooting thana box or twoof ammunition per year.
That's why my mantra always is thatthere is no functional difference between so many calibers and cartridges - there just isn't any functional difference in trajectory or power delivered at the maximum range most of us can and should be shooting at. Just my opinion of course, but something I've learned by hunting with a bunch of different people with different guns in the field -they all think LONG and HARD about taking a shotbetween 250-300 yards, and almost never take a longer one. When hit at those ranges, the moose or deer dies the same whether hit by the .270, 30-06, 7 mm mag or 300 mag. (just listing the guns most people hunt these animals with).
It is indeed always an eye opener for me when I start practicing shots at even 200 yards after sighting in at 100. Going out from there it gets bleaker and bleaker!
