Awolf,
Yeah, the 20g BSS. Just tossing it around. Nothing set in concrete. I cancelled my $4k fully loaded RBL earlier and elected to pick up this additional 20g BSS in strght stk 26"bbls (I have a PG 28"/20g already). It's right at 6lbs 8oz and handles nice, but is a bit forward balanced. BSS guns have fairly thick barrels or at least all mine have. So, it was thought to lighten them and I also recall a thread a while back where someone had done some overbore comparisions on the 20g and found good results. I have found the BSS guns to be of excellent machining and well above average for hardness and wear of the components. So, I'm giving some thought to a customized 20g quail gun to supplant the RBL.

Miller,
You're probably right about any conclusive evidence on pattern improvement across the board, but even if it was an improvement with only a handfull of my commonly used loads, I may consider it.
