I posted in another thread about loading .690 Round Balls as slugs for 12 gauge. Since I was posting based on notes I made a couple years ago I thought I would test fire a few rounds to verify the information because there is not a lot of load data for round balls and even less using HS-6 powder. This is what worked for me YMMV
Going from the my notes 30-33 grains was the load range so, I loaded 10 rounds at 31 measured by hand and 10 at 32.4 (Lee Load all 141 bushing as dropped). All rounds were fired from an 18" smooth bore Mosberg 400G pump shotgun.
My loads were Win AA and Universal Hulls
Western trap wads with 2 under shot cards No petals cut off
31 and 32.4 grains of hs-6
Lee cast .690 pure lead ball aprox 1 1/8 oz
The rounds fired and cycled well in my gun with no feeding or ejecting issues. The one thing that I didn't have in my notes is that there is a fair bit of recoil compared to the 1oz cast slug that I normally load at 32.4gr of HS-6. The Rounds were high at 25 yards but once on target destroyed tide soap jugs filled with snow in a shot or two.
I shot lightly alox lubed and dried as well as unlubed balls with no difference that I could see or feel.
Sorry, no camera to post pics. Hopefully this helps others looking for .690 RB load data as an alternative to shooting 7/8 or 1oz slugs.
