I use an old Bair loader and hand dip my powder charge. 83 Grains of 2F topped with an over powder card, cushion wad, and 1 1/8 oz of #6 shot. I load this in those El Cheapo Federal hulls from Wally world. (use the shells fer practice 'n then reload em with BP, throw em away after I fired em once with BP)
Regarding wads 'n scatterguns. As already mentioned some folks get better patterns with plastic wads and BP. I've exchanged thoughts with a couple of BP experts about this and the concensus is that plastic wads will give better patterns in new guns but old fashioned card wads will do better in older guns. There's an explaination fer this phenomenom. Newer guns are chambered and bored different than the ones made back in the earlier years of cartridge shot guns. Sometime in the late 60s manufactures started chambering and boring thier guns to take advantage of the plastic wads that started to come into use then. By about 1980 they pretty much had it down pat and could get superb patterns with the new reloading componants available. However, the newer guns didn't perform as well with shells built around the old card & cushion wad stuff. This really wasn't a problem because most reloaders were happy to go with the newer stuff for loading anyway. The few guys who did stick with the older card wads found that the newer guns were blowing the patterns all over the place and eventually switched over. Meanwhile, the guys with those older guns were finding they were getting REALLY tight patterns and even seeing a lot of "clumping", as if thier guns were overchoked. (which they WERE with the newer componants) So a lot of those old guns ended up in the closet and shooters didn't use them much. (this is a good thing, now cowboys can find them cheap! :grin: )
Anyway, my scattergun is an antique Crescent 12 bore, imported around the turn of the last century. I tried loading with plastic wads and got bad clumping in my patterns, along with gaping holes in it! After fighting with it for a while I was about to give up on it when I ran into an oldtimer at the range who put me on the right track. "Try these" he said and handed me a box of old card & cushion wads. I did, and the rest is history! That old antique will now throw patterns that a humming bird would have serious trouble trying to find a way through! :-D
Another very real aspect of loading BP in CAS scatterguns is choke! A friend of mine brought his sawed off Rossi to the range and we found that his gun was putting "doughnuts" on the pattern board. He was using card & cushion wads in a gun with no chokes at all! The wads were blowing through the shot column! He went to a plastic wad and this cured his problem. Sometime later he had a screw in choke system installed and found that he could get very good patterns with the old fashioned wads....Go figger! :eek:
