A factory 150gr with a quality bullet like the Rem Cor-Lok or Federal with a Partition will work all the way out to 300 yards on big Nevada Mule deer but the high velosity might also destroy a little more meat, where the slower 165gr bullet will also work
and not "Blow up" the area of impact.
Todays ammo has enough energy to reach out 400 to 500 yards on deer if your rifle and skills are tuned,for the task.
Even the "Light Recoil" loads will work to 200 yards and if placed right, 250 to 300 yards if not an off angle shot and
can be placed behind the front shoulder for a heart/lung try. Asking this slow bullet to penetrate more than 14" is
asking too much,out of it.
Never know, your rifle might love 180 gr bullets,like mine....................?
For some odd reason it does not like 150gr bullets, but will group 180 and 200gr bullets.........under 1" at 100 yards.
Here is the energy at 400 yards for factory ammo:
150gr 1215ft/lbs .......... 165 @ 1450 ..........180 @ 1460 ...........200 @ 1763 1,000 ft/lbs beingthe gen. rule needed.
A 165gr bullet with 55grs of imr 4831 in my rifle has only 2530fps but 1209 ft/lbs at 400 yards, equal to the factory 150gr bullet.
12/14/11; with 16 degrees here in Reno this morning, you might want to wait til Spring to go out and test any loads..........
