Well, I got some time to persue my 20 Bore DR loading.
I loaded some 350 gr balls over Blue Dot with 20S1 wads and 1/8 nitro cards in Multi-hulls (8)
Also did some Hammerheads over Blue Dot (just 2)
Did some of the BPI DGS slugs over 800X (8)
I did some more of the 350 gr RB over Trailboss, in RMC Brass, added lube in the case neck. (8)
Did some RB on a wad column over Blue Dot, RMC brass lots of lube in the neck (2)
The idea is shoot 2 over the chrony, out of the H&R SB1, check for issues if OK
Shoot 3 Rights and 3 Lefts out of the DR for accuracy and regulation.
The afternoons labour.
The wad column combinations.
Will post targets after shooting.
Nitro .
