Re: 50 Allen Tactical, Initial velocity test results...
Why don't you try a Lead sled? Are you shooting from a bench or bi pod? I have one for load development. Put 100 lbs of shot in the slead and you have a 100 lb rifle. Works for me. Saves you from bad habits in my opion. You could borrow mine but I am in KY.
My two cents. Someone well say why this a bad idea I am sure.
