I knew there had to be a good use for grits! (said the northerner! ) Kidding, I actually like the durn things.
I have used grits over powder in black powder revolvers and as packing in the loose shot in a smoothbore shotgun to prevent the shot from deforming, but never thought to use it in a rifle. I wonder if a small card wad over the powder and then the grits might help, too.
MUzzleloading season is three weeks away and I am dialing in the ol' swamped barrel .50 flinter at this time, something else to tinker with! Thanks!
