[QUOTE="greenejc, post: 1755141, member: 60453"] Maximum loads in the 7mm Rem Mag in the Speer, Lee and Hodgden's manual show 2900, 2950 and 2900 range respectively as a maximum velocity from a 24 inch barrel with the most effecient powders listed. Keep in mind that some of the shooters of this round use 26 in. barrels, which give a 70 to 100 fps boost in velocity. So your velocity is about right, since the Alliant manual gives a maximum charge of 63.8 grains with a 175 grain bullet in RL23. The Lee manual doesn't even list this powder with the 175 grain bullet. The speer manual lists it with the 175 grandslam, but at a max charge of 61.8gr. and a max velocity (24" bbl) of 2800 or so velocity. Also keep in mind that these velocities are attained in test barrels, and will vary when using commercial barrels, sometimes by over 100fps. If you're getting good accuracy, and can make good hits out to your personal maximum distance, an extra 100fps or so isn't necessary in my opinion, but if you do want more, you'll need to go to a different powder, I think.
