I have not bought any factory ammo in about 3 years, since I started reloading. My handloads are more accurate then any of the factory loads I tried. In my 06, I settled with IMR4350, 55.5 grains for my 180 gr. load (Sierra prohunter, and Hornady BTSP) and 55.3 grains for my 165gr. load (Nosler Balistic tip and Accubond).
I loaded some 165 gr. Accubonds over 55.3 gr. IMR4350 for a friend last year and he dropped a bull elk at 250 yards with one shot, where he stood.
I'm getting about 2580 FPS with the accubonds, 2625 with the prohunters, and 2700 with thw Hornady BTSP (crimped). Winchester or Federal Match primers.
