My shooting bud and I have done some preliminary work with RL17 and 3 different 140g bullets. With the chosen load for each bullet, we found we are exceeding book velocity (2725) with a powder charge below max charge wt (42g). I will qualify this by saying that we ran only 3-4 rounds of each over the chrono....and they were shot out of a 28" x-caliber barrel.

Just something to watch for, depending on how you view lawyer loads, velocities, pressures, etc.

Seems someone here has done some work with RL17 and temperature......was that you Robinhood?
