My 300WM has kind of been retired. Had pretty much settled on shooting the 180 grain Accubonds over 75 grains of RL22 at 3148fps. Had a 7mm RM built on a Borden action that I'm shooting the 180 grain Bergers out of. Shot my antelope at 910 yds this year and it didn't go 10 yds. My 7mag is my carry rifle about 8lbs all up. My true long range rifle is my 338 Edge. I have gotten several first round hits at 1780 yds on a 13"x18" target. Shooting out to 500 yds. is pretty routine now. Past that, things get more complicated. Now I carry a Kestrel to measure temperature, wind velocity, and station pressure, a ballistic program on my cell phone, and a rangefinder. Setting up for a long range shot could take up to 20 minutes. I'd still encourage you to look at the heavier bullets. You won't be giving up much in trajectory, will be better in the wind and hit with a lot more authority when it gets there. Lastly, when the game shows up at 50yds, there is less chance of the heavier bullet blowing up on impact.
