Load used is the 120-grain RCBS bullet over 7.5 grains 2400. What I've been doing is resizing the first 1/3 of the case, then expanding the case mouth just enough for the bullet heel to enter. That holds the bullet tightly enough that it won't fall out in transport, or if I pick the cartridge up by the bullet. Here's an average group at 30 yards
Took five rounds just like this and crimped them.
Last is five rounds where I didn't resize, just seated the bullet into the case(they'll damn near fall in), then crimped
I'm going to have to shoot them again to see if the unsized cases shoot not quite as tightly or if that was me spreading them slightly. Either way, significant improvement in group size.

Have you tried Rooster Red Lube?
Acts like glue to hold bullet in case.
Was recommended in some article I read a long time ago re: 310 Cadet
He was reliably hitting a gong at 600 yards - don't recall how big it was.
Another in the list of "Details Improve the Big Picture".
Would be interested in primer/powder/bullet profile info as well.
Thanks
CCI small pistol, 7.5 grains 2400, the RCBS 120-grain bullet for the Cadet cast of 15-1 alloy. All loaded in a modified Starline case 1.130" long.
Haven't tried Rooster on these. So far I've been getting good results(other than not sticking) using the modified Lee Liquid Alox on these.
