Came across a Ruger blackhawk .44 mag that was converted to .50AE. The gun is gorgeous BUT...Is the conversion even possible to do and still have the gun be safe to shoot? Granted anything can probably be done for insane amounts of $$$ but within reason? Id be wary of the barrel and cylinder not being able to withstand the pressures. I cant find anything anywhere, where people have done it to a revolver. Lever marlin, yes. any thoughts?
