I shoot a 30" BPS with a .665 Indian Creek. With W-W XX 3.5-2-6s it will put 230-240 in the 10" at 40 yards. With W-W XX 3.5-2-5s it will break 190 at 40 yards. Heavy 7s will go 320-330 but I didn't like the actual kills as good as the #5 lead. More shot hits the head but the #5 seems to slam em harder. reflexl
