Yea, I've been trying to do some research as well but can't find anything I'm really comfortable with, especially considering the results. For me, I was simply looking for a "pistol caliber" rifle barrel that I could use legally to take whitetail with here in Indiana. I ended up with a 45/410 in Super 16, and, for the ranges we usually encounter deer here in southern Indiana, I think the so-so accuracy of the 45LC out of this barrel will do just fine for me. If I need more accuracy or longer range, I'll take out my 209x50 Encore.
On a side note, I would love to load up some 45LC with black powder. Anyone have any loading data to do so? Curios about powder volume and rough velocities. I currently have a 300 gr XTP bullet, but could play with other weights if needs be.
Thanks!
