If you are sizing your brass for just one rifle, why size it any more than you have too, or over work the brass? Some just necksize and occasionally full length size when they need to bump the shoulder back a couple thousands.
I would screw out the die one full turn, size one piece of brass and try to chamber it. If tight, then screw in slightly more, say 1/4 turn and size again, try to chamber, repeat until the brass chambers without a lot of resistance. Run with that setting.
