I have some 20 ga shells my son loaded some time ago and am getting a lot of poor ignition in them? Has anyone else had trouble with trap-100 powder?
The load is a Wnchester AA 2 3/4" hull WAA20 wad Winchester 209 primer and 15 grs. of Trap-100 powder. This is out of their book and is supposed to be a 10100LUP load?
