looking for a load for 300 wm 168 berger for long range hunter

I'm looking for a load for my lrh 300win mag with 168 Berger anyone got any suggestions. I'm looking too do some long range hunting. Ive used rl22 in my other 300 but not with Berger's.

Berger Bullets really vary performance-wise from Rifle to rifle. You will probably just have to take your favorite powder and start playing around with loads. I usually start about .010 off the lands and find a powder charge it likes, then start creeping closer to the lands to see if it gets any better. Your OAL may be limited by your Mag box.
