Butch, 300 Win Mag cases are all over the map for capacity. Norma is on the high end for capacity while thick RWS or even Remington could have several grains less capacity than Norma or Winchester. I'd start low and let your chronograph be your guide. The speeds/PSI's listed on QL are legit but the actual case capacity, burn rate of your powder and a few other things will dictate the actual charge. Good luck.

Bad news is the chrono speed on the 165gn sierra gameking is only 3070fps with the 4831 ..
good news is the rl25 and the 180 ballistic tip shot a .7 group at 3050fps ... the 165 AccuBond with the rl22 shot 3290 fps ... I have a ladder loaded with the 165 sierra gameking hpbt and rl22 and see if the speed will pick up some ..
thanks again yall for all the help
