A friend of mine used to shoot 1 ounce at 1350 fps:muzzle. I shot 1 ounce at 1180 fps: muzzle. At 40 yards the difference was only about 50 fps.

A technical question... I was curious how you measure the velocity of the shot at 40 yards? I have a chronograph that I use to measure muzzle velocity... do you just set your chronograph behind some type of barrier and are then able to catch the shadows of pellets flying by 40 yards away? I have just never tried it and was curious how you set up to do it.

I’m not certain how they do it, but there are tables in the Lyman manual.
