Raider - I'm about 5 miles west of Garrisonville (610), off Joshua Road. I'm a member of the IWL also. Shoot there quite a bit, weather permitting. They have a nice archery range but I haven't carried a bow in years. I'd just embarrass myself. Come on out and watch me destroy my remmy with these hand loads!
BTW, I saw on a website how a fellow used a 45lc shell and made some snake shot loads. I figure 15-20 gr bp, over powder dry lubed felt wad, some lead shot, then top it off with a ball. The ball holds in the shot and helps it keep a better pattern. Leading could be a problem.
