yep, bought a box today. they are just as quiet as cb's and hit harder. they feed well in my model 60 but lack the power to rack the bolt all the way. just a warning though, if shooting from a semi, you will get some spray out of the chamber. i experienced the same thing from my savage break action using cb's. it's due to the hotter primer they use in lieu of powder. when the rim is hit, it can rupture allowing the primer to escape out the back. annoying, especially if you're a lefty, but not serious.
