@Stefanhope An idea for you to put away and possibly investigate later: A Lyman M Die.
What it does is gently flare the case mouth a little to make seating flat based bullets easier.
It doesn't take away the need for trimming, deburring or lubing, but does make the process easier and smoother.
If you're confident enough to seat a projectile at this point, here's another suggestion:
Make a dummy round. Put an unprimed, sized case in your rifle and check that the bolt closes smoothly.
Use an unprimed case without any powder in it, and seat a projectile in it, wind the seating die progressively down till you have bumped the projectile down to the proper depth.
Then take it off the press and check that the projectile is seated without any weird looking bulges at the base or side of the neck. Hold it next to a factory round if you still have one left, to compare it to.(You're comparing the look of the brass at this point, not the respective lengths of the two rounds.)
You'll have to sacrifice a case and projectile to do this with, but I have found that it's well worth it to learn.
