Great site! Big bench slug and RB guns are close to my heart. I am still quite new to the sport but have been gaining as much info and practicing when I can. I have spoken with the very knowledgeable Mr. Wasserman, who I see posting here, and learned a great deal. My toys are
RL Morris
.45 RB, aperture sights
.62 RB, aperture sights
.485 slug (650 g 2 part slug), Mitchell scope

Breisen 
.69 slug based on a Resor (tooling)(1750g 2 part slug), Mitchell scope
32-40 ballard breach or false muzzle seat, scoped but I change it up(unertl/balvar)

Pierce
.45 slug, (450 g 2 part slug) 1860's gun, slug design reworked slug by Lester Cox, it did quite well at Camp Perry by Mr. Cox in the 1960's at 600 yards, scope or original aperture sight

Other precision RB
.50 Sinclair custom, built by Fred Sinclair, aperture sight, modern inline,custom?, Jewell trigger etc
.45 P. Davidson, offhand schutezen style, aperture 
.50 Herman, bench schutzen/?, aperture
