Look what the little brown Santa truck driver just threw up onto my front porch:
And yes, this is a rifle, not a shotgun (notice the sights on the barrel rib). It's a 12 bore muzzle loading rifle, designed to shoot round ball only - over a rather hefty charge of black powder. It's kinda heavy at about 12 pounds, but it balances nicely, and I bet I come to appreciate its weight after shooting it a bit.
I'm still waiting for the bullet mold to arrive. It shoots a .715" diameter round ball of about 500 grains weight. Soon as the mold arrives, I'll be casting up a few and heading to the range.
The challenge will be getting both barrels to print reasonably close to one another at, say, 50 yards or so. Unfortunately, this thing is not "regulated" in the same manner as the high end breech loading doubles are, wherein the gunmaker continually shoots it, records points of impact, separates the barrels and shims between them, re-solders the upper and lower ribs, and tries again. This is a painstaking, time consuming, and therefor very expensive process. The manufacturer of this particular rifle forgoes that to hit a price point. There are, however, a few tricks that can be employed on a muzzle loader to accomplish this same task, assuming we aren't starting too far off.
Anyway, should be lots of good, clean fun...
