[QUOTE="Mysticplayer, post: 3925, member: 8947"] Huntaholic, you have pretty much described the effect of game shot at long range with conventional or premium bullets. At low impact vel, even when the "energy" numbers look good, there is little effect on game. Problem is simply not enough vel to open up the bullets or bullets too tough for the impact vel. As S1 suggested, try the 162gr Amax at 3300fps. This is a fragile bullet at high impact vel. but becomes a "controlled expansion" bullet as vel slows down. Very high BC and a very accurate bullet. Conventional softpoints need about 2000fps to work well. Premium bullets like Barnes X need a whole bunch more (my guess is 2400fps and up). Some match and varmint bullets, as well as the Nosler BT and Hornady SST expand readily down around 1500fps. I was there when a very large moose was taken with a 120gr BT launched from a 7mm rem mag. Conventional wisdom would say that this combo is nuts. Bullet weight too light and too fragile. However, when the bullet hit way out there, it had slow down enough to expand and penetrate to the offside shoulder. Moose was down in a couple of steps. Live weight estimated to be over 1000lbs. 62" spread in the antlers. How far? Not sure as this was before I had rangefinders. However, it took us over 20 min to walk there over fairly flat ground. Would guess that it was at least 750yds. Speed up the muzzle vel., or use a more fragile bullet. The shock effect is not going to be there but well placed shots will take game down quickly. I have a 300RUM in the works with a 35" barrel. It should launch the 240's at 3100fps or so. The impact vel at 1000yds and beyond should still be sufficient to cause expansion. There certainly is enough "energy". Refer to DC for his results on game with a similar and larger combo. Hope this helps... Jerry [/QUOTE]
