barnes bullets will do that considering there basicly a solid with a little hole in the end of them or covered in a polymer tip,good bullet choice pretty impressive for a little 308. i've done the same thing with a 225 gr accubond at 3255 fps out of my 338 RUM, man i love rifles with serious horse power. I cant remember what forum it was in on here, but it floored me, it was john burns and a teen age girl hunting elk with a 243 and a 105 gr berger, WT*,,,,,, im sure that im gonna catch some real flack for this, and i dont care but i gotta say somthing, since we are on the topic of REAL ELK BULLETS, ya it was a good shot, ya she had Burns coatching her, ya she hit it DIRECTLY IN THE SPINE, and yes it went down, BUT now give that same shot to a person that saw the video and now assumes he or she can go out and buy a 243 and throw some 100 gr bergers in it, throw a half decent scope on it and call it an elk rifle, put a not very experienced shooter behind it, throw a 5-15 mph varying from left to right wind into the equasion, and all i see is absolute dissaster, and a bunch of wounded elk with target bullets in there guts, John burns is a good shot dont get me wrong, case in point suppose we have a 243 win that you can actually get 3000 fps with a 105 gr berger, at 700 yards it has roughly 7-800 foot pounds of energy and nearly 30" of wind drift with 10 mph wind and 90" of bullet drop if zeroed at 200 yards.....now compare that to a 338 ultra 3200fps, 225 gr accubond zeroed at 200, 70" of drop, 20" of wind drift, OK OK OK now most of you are sayin "well thats not that much of a difference" ya its not, except the fact that the 225 gr bullet has 2500 foot pounds of energy on impact and is still traveling 2250 fps, i would rather have a bullet with over a ton of energy hit behind the ribs cause of the wind than one with just a little more than a quarter of that. Now im not rying to say that everybody should go out and by a super magnum and throw some huge peices of lead down range, everybody should shoot the biggest gun that there comfortable with wether its a 6.5-284 or a 338 Allen magnum, it all still comes down to bullet placement and lots of practice, LOTS, all im saying is if you are going to get into the long range game, dont just watch some video of some random person shooting a cow elk at 700 yards with a varmit gun and target bullets...i mean 243 win (sorry if you think the 243 is a perfect long range elk cartridge) do your research, ask around, ask questions on here, heck there are more guys on this site that have killed animals over 500 yards then you can shake a stick at, and they are all very helpfull and very knowlegeable, so dont feel as if there is no help out there, get the biggest gun you can comfortable shoot at long distance with a good well constructed bullet and practice alot, and only take those shots if your a 150% sure you can make a good hit on that given animal, we all owe it to them to do so ... just my 2 cents
