Hey Steve,
I started with this bullet / rifle combo when I got into F Class Mid Range. I used the same setup, but with RP 71/2 primers and RL 15. They produced great results but when I started getting "focused" on my reloading I discovered a huge difference in the length of the "bullet" itself. I would recommend that you seat the length based on the ogive. The ogive measurement was consistant with those bullets, but length cause alot of frustration, cussing and now counseling.....
