ok, i did a test with my 10 ga EH 30 in 2 frame choked .021 in both barrels. i loaded 8's with a 1 3/8 th oz mec bar but it droped only 1 5/16 oz the shot count came to 553 to the load. i than shot it at a 30 inch patten board at 40 yds and i got 383 in the 30. this is .696% . ok this is not 45 yds and i did count the 24 in circle. (289) i do know nothing would have got out of the pattern with out a hole in it if it were bigger than a mouse
