I have a H&R single-shot 12 ga. It has a 20" barrel with no choke. I've got some brass hulls and some goex. I kind of like the idea of hurling a lead ball out of there, and I'm wondering if anyone has experience with this. Specifically I was thinking of getting a .710" ball mold from Track of the Wolf, but I do not want to bother with this unless it may prove just accurate enough to be fun. Thoughts? Opinions? Pictures? EDIT: I should mention the Goex I've got is FFFg.
