I found an old box of Win XX 2 3/4" 1 5/8oz 6 shot. I thought is was good pattern for 40 yrd. in a Ben SN, JH .655 The paper I was using is 17" x 22". One had 96 in the 10" & 210 on paper, the other one had 87 in 10" & 235 on paper
Not to shabby for a 2 3/4 shell.
Not bad at all for 1&5/8 oz.
I loved those old 1-5/8oz Winchester shells
a many a bird fell to some of them out of a Mossberg 500 with the factory full choke tube,years ago
My wife's 535 and a friend's mossberg have also shot very even patterns with old winchester 1 5/8 shells!
