[QUOTE="RockyMtnMT, post: 1452368, member: 7999"] What vel are you getting with the 131's? This is a tough combo to beat out to pretty long range. On another note...I think energy is a bit of an arbitrary number that is good for comparing cartridges. With well constructed bullets impact vel is a better comparison. The gains from the heavier/higher bc bullet usually show up in wind drift. Then at a certain range the heavy will eventually win in every category. Often this is farther out than what is an effective range. If a rifle is being set up for truly long range hunting and the shooter is willing to use impact vel below 1500fps then the high bc bullets take over. This usually will mean ranges well past 1000y. To the op: When I am trying to decide on a bullet I will sit down with the JBM Ballistics calculator and load the prospective bullets in with the expected vel and print out each chart so that I can lay them down sxs and compare the difference in performance from muzzle to whatever benchmark you personally have for the longest range you are willing to hunt. This may very well end up not being the bullet that you think. I tell people all the time that if the highest bc heaviest bullet with low muzzle vel, doesn't give you the overall best performance for your hunting style, it doesn't mean that you can't shoot long range rocks with the lower bc, lighter faster bullet. You can still bet sodas with your buddies on who can hit the 1500y yard rock. Steve [/QUOTE]
