Head on over to shotgun world forum, thay have their own page, and I got a coupon code good for 10% off there. I shoot them in my Elsies, the only thing I have noticed is they stick in the chamber a little and hang up the ejectors in my 1927 field grade. It might just be a quirk of the gun, and it really isn't a complaint, just passing along what happened to me.
