I just bought a bottle of Longshot for $31 at OutBack Arms in Plympton, Mass. My dilemma is that I normally use 20/28 for my 20 ga 7/8 loads. While Longshot may be used for 20 ga reloading, its basically a magnum powder from what I've read and I don't want to shoot magnum loads (20 ga) thru any of my vintage Parkers.
I need a light load recipe for this powder.
Would 14.2 grains powder bring the pressure down sufficiently? Anyone have a suitable recipe for 20 ga field loads with this powder for vintage parkers?
