Does anyone remember the shells Remington had out a few years ago? Remington ringmaster HD? They come in a box of five. I found some but haven't shot them. Are they good shells?
I had good patterns with the 3in #6 shell out of a M2 .660 Carlson. Solid dense even pattern to 40yds. Buddy waxed 3 birds with this set up when he borrowed it.
