I have shot rifled slugs many times from my old topper 88 410, which is now my sons, and from my newer pardner 410 bore. That I've had made into a slug shooter. It now is a cylinder bore and wears a 4 power scope and is an excellent little slug shooter. From my experience so far I believe the Brenneke 3" 1/4 oz. is the best. Perhaps others have it different for them, but I have found that consistent accuracy with just the bead front sight out to 50 yards is not good with the small diameter barrel of the 410. Good luck with your 410. scout4<><
