I tried cast bullets in the hornet and just couldn't get good accuracy at the lower vol....
With the Lil'gun load I posted on page one, switching primers completely ruins the groups. I didn't make note of which primers I had shot some of the first groups with - I only knew they were silver. When I made another batch, I used Federal pistol primers thinking I had used a 'milder' type with the low charges in that load. My groups became very erratic so I tried the CCI 450s, the only other silver primer I was loading Hornet with. Those brought the groups back together again, something that was kind of a surprise given the small charge of powder involved. (The charge thrown was with the #5 rotor for the RCBS Little Dandy measure; the target says 5.8, but I believe the charge is actually running 5.6 or 5.7 grains.)
I'm sure I can fiddle with those loads even more and find additional improvements.
