I had a .45 long rifle model that I shot a good bit in-between rifles.
the rifling was very shallow (gun was from the 1990's) light to moderate powder for target loads were accurate.
hunting loads were not accurate, that was fixed with cornmeal on top of the powder under patched roundball
double set triggers were ok to good but not great
the lock was the weak spot in this rifle, mainspring was ok, the pan was tiny and the frizzen was bad, shoeing the frizzen fixed that problem
I think L&R offers drop in locks on some models, that would be the way to go
I had a .36 cal Blueridge and a Br Bess kit I built. Both were great. Local clubs were happy when I parted with the Bess. She was a steel target destroyer. I'd break off and crack 3 or 4 targets a match. She left no doubt she'd hit what she wanted too. Great with ball or shot. The .36 was a fair shooter but was finicky about load configuration. But fun and inexpensive to play with at the ranges and matches. Those were more than 25 years ago. I'm into building my shooters now. The one I use now was built by me in 1994. I'm now finishing a smooth-rifle in a plain Lancaster style.
