Inexpensive and accurate in one rifle I tried it in. Shot a 180lb pig with it at 20yds. Went through both shoulders and the 6" tree behind it.

Used 1 newspaper and 1 felt wad over 80gr ff.

I took a cutoff wheel (didn't feel like setting up the lathe) and opened up the top driving band on the mold so it would engrave on loading (.505?)

Good luck
