Using BR-5 powder bought in January of this year. loading .38 spec w/WSP and 4.5 grns of BR-5 with 147grn pill on top. Problem is ignition , Unburned powder in cylinder and on shooting table bullet stuck in barrel. Out of five test fires, 3 in barrel , one fell out of barrel onto ground and one shoot but very weakly.. OPTIONS ??? Primers seem good ( work in other Unique loads) . Powder BAD??? ( hope not just bought 7 lbs) Solutions are what I'm seeking. Any thoughts???
