I saw a video of a guy shooting a 20 ga nef or h&r shotgun he'd loaded like a muzzle loader. Darn, I had to try that.
Got the shotgun, an nef break top 20 ga. Needed to shoot a couple of shells to get the bases needed for the task. Cut all the plastic off the bases and decapped the bases and stuck another 209 in them. Four cases in all.
Put the primed base in the gun, close, pour fifty grns 3F down the barrel, force a cleaning patch over the powder, pour in seven eights Oz. shot, force a patch down on top of the shot. Loaded.
Shot it, and it did what it was supposed to. Put seven number six shot into a soda can at about 85 or 90 feet away. The pattern seemed ok at that range, centered the can.
Shot all four bases that I had and it worked all four times
Just a fun thing I had to do. Anybody else here ever try this?
