I've never seen one on the line at the nationals. Nor the Lodi regionals, nor the Phoenix regionals.
You would have to rework them so much that one might was well start with a much better action in the first place, and come put money ahead, with a better rifle too.
Sure, it can be done, but it's hardly a great choice.
Quite a few make them into Schuetzen rifles. they are much better suited for that - with a modern scope as the ASSRA allows.
If you just want to power lead down any barrel with blackpowder, you can do it with any rifle made. Hell a Model 70 will do it if that's all you wish to accomplish. But that's the reason that the OP never hears about the #1 as a BPCR - it's because they ain't legal, never will be and never should be, for the sport and they wouldn't a great choice if they were.
