Thanks for the replies Trex, MD, and Dwayne. I'd like to get away with not crimping. This first round of loads was done with new brass so I didn't FL size the cases, just ran the expander ball down far enough through the necks to round them out (yes MD, I read your stuff, thanks for the tips) so I think the neck tension might be a little light for a tube magazine.
I'm thinking on the next loading I'll size in two steps, first run the expander ball through the neck, then remove it and FL size without it. Hopefully that will give me enough neck tension to work with the rifle. It'll be interesting to see how that works this first time, and then with multiple loadings on the brass.
