Public range w/ factory guns and low quality, mass-produced ammo (poss substandard optics, shooting form too) OR private range w/ accurized or fully-custom rigs using pet handloads? Nearly all rifles here (including 375 & 416) can do it under the best conditions (even accurized/handloaded Rem7600 pumps and rimfires and even some out of the box Rem 700 and Ruger 77s using premium factory ammo,) but 5 of 'em can do it at anytime (custom, handloads-just perfection at a price-.257/.264/.284/.308/.338) and 2 more if we're including 22-250! I agree that the vast majority would not, off the cuff. It's that damn bell curve! Some of us are fanatics. Time permitting, when I really need to dial in a rifle perfectly, I'll go to a climate controlled indoor 100 yd range. It's like a lab for a perfect sight in (no wind, sun in your face, chatter/distractions-can have the place to yourself at times, 68F) but most are dialed in on my own 100/200/300 yd range when the weather is perfect (perfect meaning on the hottest days of summer for Africa or the SW and on a 45F or less day for hunting in the N. US.) It's important to test your pet handloads in the extreme heat prior to heading out hunting, as some powders take on different personalities. Even the widely varying bench designs can have effects on group size (i.e. sagging/bending thin plywood vs. rubber pad on concrete, etc.) I recall testing my shots with NO caffeine and after a dose of caffeine, and would you believe NO caffeine worked out better? I thought it might improve things, but it did not in my case. It becomes important on the long shots...
