we had a chance to shoot it today. Results as follows:
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.
