My process...
Shoot
deprime
tumble
wire brush primer pocket
clean
lube
FL size
Trim to 2.610 give or take .002 (new step)
chamfer and deburr
load
Why am I getting a slight groove on the inside of the neck? It has to be the centering pin in front of the cutter, and there has to be a little side press from the two sides of the trimmer not lining up perfectly. Though, the left side that holds the case has wiggle room to move when the alignment pin goes into the case and lines it all up to cut flush. Is this groove somewhat normal for some folks? I have fine grit sanded the centering pin and it is perfectly smooth to the touch and cotton.

Just load and shoot them.
BTW trimming cases is the absolute worst. I avoid doing it whenever possible. 😆

Its just a mark from the 30 cal button(?) riding inside the case mouth. Likely is just superficial and not impacting the brass whatsoever. Can you feel it with a paperclip?

:yeah: I have one that’s a 7mm guide that leaves a light ring like that after trimming. Even though I’m also agreeing it just superficial and shouldn’t impact anything. Call rcbs and they will probably just pop a new one in the mail to you.

I just bought that universal one and can easily return it. I polished the pilot with wool today, still made a small mark. Also, no pictures of pre sized cases, but there is no mark before trimming, only after, clearly happening with the pilot centering pin thingy inside the neck when rotating to trim. I can feel the grove with a paper clip but doesn’t feel deep. I plan to load them and see what happens. Hopefully I don’t die.

If you’re mostly sizing necked cartridges, go with the Frankfort arsenal case prep center or other electric / drill powered trimmers. I love the Frankfort arsenal because everything is in one unit. It has worked awesome for me. It does not work on straight wall cartridges…..that’s what I have my Lyman for.

I know nothing of the power case prep world. I’ve never trimmed before and only hand chamfered and deburred. When the cases got too long, I tossed and bought new cases. That worked for more reloads than I thought it would. And I’m not sure why I’m deciding to trim now, but I am.
So, that Frankfort will do everything case related including trimming, it seems. Why would I not do that?

Thanks. No straight walls for me. Only 300wm, 270, 22-250.

Yes and it will save your hands from cramping up while manually doing the same. Fast, easy, and a no brainer if you ask me. Easy to set up and easy to use. If you get one I am happy to give you a few pointers that makes it use and set up very easy.

Will order the Frankfort soon, unless there are more suggestions by others. That are under the 200 mark.
