T, in an upcoming issue of Varmint Hunter magazine, I've got an article entitled, "Portable Range Design for Long-Range Testing" pending, in which I detailed a very simple method of making portable targets to set up in the field, to test guns/scopes/ballistic programs for their effectiveness at ranges farther than point blank. Think about it, if you're shooting a .22-250 or similar small caliber cartridge to say 300 or 400 yds., doesn't it seem logical that a heavier, higher B.C./S.D. bullet will reach out farther? They do, easily. Would 2X the bullet weight go twice as far? 3X, 4X, etc. Of course this is a little idealistic and there's the accuracy/atmospheric conditions to contend with, but believe me until you've shot at long-range in a deliberate, focused manner, you'll never know how far you can go. Try it some time. I have and my learning curve has spiked dramatically since I started doing this several years ago. I'm not saying that shot wasn't lucky. But it sure beats guessing, if you approach it systematically. I've seen this stuff work too many times in the field, UNDER THE RIGHT CONDITIONS to know it is all luck. A couple of days later I took another dog at a laser-ranged 450 yds. and a day or so later I shot a pr. dog with one shot at 489 yds. in a 20 m.p.h. x-wind.
