Remember in the original question, he is talking about long range accuracy ON GAME ANIMALS not targets. So we have to consider 1. can I hit it? and 2. does the bullet hitting it have the power to kill it humainly?

I have never shot a 6.5 X 55 Swedish but have always herd good things about it. James B says he has taken deer at 400 plus yds.

Looking at a Winchester ballistic chart (I know that these factory loads are not near as hot as a good handload could be) the muzzle energy (power) of a{140 gr. bullet} 6.5 X 55 at 400 yds. is still 1048 ft.-lb. That is more than a 30/30 at 200 yds. and is probably quite enough for deer sized game. By 500 yds. it has fallen off to 878 ft.-lb. ( the figures for a 25/06 with 120 gr. bullet are about the same) Is that enough power to effectivly kill a deer? Well it is more energy than a .44 rem mag. handgun 240 gr. bullet has at 50 yds. (623 ft.-lb.)

However look at the energy of a{140 gr. bullet} .264 win. mag. at 400 yds. (1389 ft.-lb.) and at 500 yds. (1139 ft.-lb.)

Or a {150 gr.} 7mm rem mag. at 400 yds. (1448 ft.-lb.) and at 500 yds. (1160 ft.-lb.)

To kill game at long range you must :1. hit it in a vital area (accuracy and shot placement) and 2. hit it with enough force or power to kill humainly.
