sometimes, i use a .32 cal. caplock pennsylvania rifle that i put together myself from Dixie gun Work parts.
it shoots a .310 patched round ball pretty accurately. i use about 30 gr. of 3f GO black powder behind the ball. i also use those wonder lube patches. when using the gun, i load several bullet blocks with patched balls and that makes the loading much quicker!
Every year during the iron sights contest at the Shawnee Squirrel Hunt (this past Sept. made 8 in a row), i use this rifle. this year i took 2 with it but lost to a feller(Sarge) who was shooting what he called a clackity clack .22. He took 3.
luck!
