7LRM and Reloader 22

how far away are you guys placing your chrono?? i'm running 71 grains of H-1000 out of a 26" benchmark at 2885. shoots great but not 3000 ft/sec. I have my chrono at about 15 feet away.

I put my chronograph 10' ahead of the muzzle and am only getting 3027 out of a 31" barrel

Magneto speed here so so close enough to muzzle velocity.
