The barrel came from Les Bauska back n '75. I think I paid him $15.00 for it. The rifling machine didn't shut down, and they forgot about it for a while. It wasn't a common practise.
: I used a .020" to .022" patch, as noted. Due to the amount of lead movement, the grooves were filled, even with the smaller .454" ball. I used .457's usually, but when obtaining an Ohaus double cavity mould for the .454's, I switched to them. I still have that barrel, incidently. Back then, I browned barrels with nitric acid - folks, it's hard on the fingers & that's how that .45 was browned. It started out at 44" but has been shortened several times, with sights and dovetails being moved several times. It's pretty much junk now, but interesting to look at, periodically.
