RE: Buck Hammer slugs
Love the Buckhammers. Bought them because Remington offered a large rebate. I tested of about five different brands before last season including Hornady, Breneke, and lightfields. Only two brands shot well from my Rem 870 - the Buckhammers and Federal Sabots. Six inch groups at 100 yards are no problem. I have a fully rifled barrel. They do hammer the shoulder as well!
I hope the first one at the range this year hits the bullseye so that I don't have to inflict any more pain on myself than necessary. For some reason I don't notice the "hammer" when shooting a deer.
