Update! Found slugs my shotgun really likes, Palla B&P ''Big game'', VERY hot loaded stuff (500 @ 1550 fp/s) but it groups very nicely and it doesn't leave a mess in the barrel. My shoulder doesn't like it though; free recoil energy is in the high 40's ft/lbs, a lot of fun when shot from the bench with a hard plastic butt pad.
Groups at 50 about 1.5'', standing without support 2.5'' groups which is good enough for me. No scope needed.
And boy, shooting slugs is so much fun, I love the sound they make when they whistle through the air and impact with a satisfying ''WHACK!''
