However, with that said, there is not a muzzleloading barrel in existence that could handle the pressure that would be created by launching such a heavy bullet. It would probably take at least 200gr of powder to launch it and I would hate to think how many 100,000s of pounds of pressure would be created by that load. One sure as heck wouldn't be standing upright after he fired it. :eek:[/quote]
I am going to have to disagree here. I use slugs in my 58 that are over 500 grs, and 425 grs in my 50. Sure..these kick....but nothing nearly like a high-powdered rifle. I don't see any harm in firing a 600 gr bullet with a proper load....It aint like the 'load' needs to equal 50BMG velocities.
The questions for ME....are 1. If 'paper patched' will it be accurate? 2. Black powder rifles usually have a deep button rifling for cast bullets, will THIS be accurate with a jacketed bullet? 3. Rate of twist would probably need to be faster for the longer/heavier bullets. 4. If bullets are resized to fit 50 cal bore, forcing a copper jacketed bullet down a 'mild steel' barrel intended for 'soft lead'. ( I have heard horror stories about Wheel Weight alloy ripping out rifling).
So....theoretically....I would say it WILL work. BUT...why bother? There are excellent bullets available for a 50 that are well designed and perform well for target shooting and hunting purposes.
