Guys,
I have maybe hundreds of once-fired Remington Gun Club Hulls, a smooth-bore Benelli Supernova Tactical pump shotgun, Blue Dot, Longshot, and Herco powders, DRA12, Remington 12S3 and DR 1 1/8 Blue wads, W209 primers, and Lyman 525 grain slugs I cast.
I have tried the Lyman shotshell recipe (Gun Club hulls, ~40-43 grains Blue Dot, Downrange DRA12 yellow wad, W209 primer) with and without nitro cards. My inconsistent accuracy at 50 yards ranges from 3 groups within 4" to only 1 out of 3 shots on the paper (and the paper is 11x17"!!). I have tried trimming or completely cutting off the petals with no appreciable difference.
The DRA12 wads that start with all petals intact have the petals ripped off (usually leaving 1 or 2 intact) and the "crush" area is always unevenly compacted. I imagine the unevenly compacted crush part is largely to blame for my poor accuracy.
I want to try a gas seal and some combo of felt filler wads and nitro cards to build a shot column that won't crush unevenly, but cannot find such a recipe with my hulls and slugs.
Any help would be appreciated
