Saw this over at the Ruger Forum.
"I picked up that SS NMBH at a local gunstore, used. I sent it off to Clements Custom 'smithing and he installed one of his taller custom front sights and replaced the rear sight with a new one. I then installed a Belt Mountain base pin and a local 'smith installed a stronger, albeit, uglier set screw to keep it in place.
The load is Starline brass, WLP primers, max load of Lil'Gun pushing the Cast Performance 335 gr WFNGC to 1150 fps. The shot was taken at 15 yds. He didn't go more than 15-20 yds."
