The norm is to knock off 30-70 fps per inch of barrel missing
due to weapon makeup and how tight it might be.
Green Dot is in the w231 ball park and in a 686 6" I can get it to
push a 158gr lead bullet with a full load at 1281fps.
My latest test with a full load of BE86 did 1271fps on 5/6/17.
Pick your poison..............
