[QUOTE="Fiftydriver, post: 130482, member: 10"] I hope my comments do not start a war of words about if the match bullets should be used on game. That was not my intent. I have no problem at all shooting big game with match bullets. My comment was only based on my experience that the smaller diameter match bullets do not perform particularly well on big game at long range where energy and retained velocity has dropped significantly. This is not the fault of the bullet or the chambering it is used in, just simply a matter of the relatively light, relatively low BC bullets shedding velocity and energy at a rate that will limit their expansion at longer ranges and in some cases any ranges. I have always found a match type bullet will colapse in on itself upon impact and then if velocity is high enough and the bullet has enough retained kenetic energy, will then force the nose of the bullet to deform outwardly in some form of a mushroom. Yes, bullet energy has something to do with bullet expansion. Also, with the larger caliber match bullets, they are larger in frontal area so they move more tissue as they pass through the target. In return, the target tissue pushes back on the bullet with more force because of the larger frontal area. Kind of similiar to comparing bolt trust in a rifle. Take a 223 Rem and load it to the 70,000 psi range(OVERLOAD!!!) and you will still have very little bolt thrust developed. Take the same receiver design and load a 338 Lapua to 70,000 psi and the bolt thrust is expodentially larger. still the same 70,000 psi in pressure but the much larger area of the Lapua case exerts that same force over a much larger area which translates into higher botl thrust. Same with a penetrating bullet, the larger calibers have more frontal area, and thus there is more resistance on them as they penetrate which will cause them to expand to a higher degree then the smaller caliber bullets. This has been my experience with match bullets in 22 and 6mm cal rounds compared to larger diameter match bullets. The 6.5mm in my opinion is on the fringes. Yes it will work great in most cases but still its a bit light in my opinion for anything larger then deer. That being said, I would never think twice about shooting any deer with my wifes 6.5mm AM with the 142 gr SMK loaded to 3550 fps. But there again, there is a surplus of retained energy working for the bullet. Again, did not want to start a debate on if match bullets should be used on game, I just feel any match bullet used on game will perform much better if its 7mm in cal or larger.
