[QUOTE="Bull_Mtn, post: 2595340, member: 105447"] I load for a .300 WSM, which is on their list of recommended cartridges. My rifle is a controlled feed Model 70. I have been using RL-16 for bullets from 175 to 200 grain with good results. I'm about out of the RL-16 and found some Superformance available at Midway. I have been wanting to try the 166 Gr Hammer Hunter. I have had excellent results with the 181 HH, at 3030 fps and after consulting with Steve, he felt I that the Superformance was a good choice for that bullet and I should expect around 3200 fps or better. I tried the powder, and started experiencing heavy bolt lift before I reached 3000 fps. I reached a peak of 2970 and after that the speed started going down, and pressure signs increased. So I gave up the project. The 181 gr HH has produced less than 1/2 MOA groups and has plenty of speed and energy out to 700 yds for good terminal performance. So I'll stick with it. [/QUOTE]
