    Which case trimmers index off the Rim Face, not the Case Base?

    Lyman seems to have 2 distinct philosophies for indexing rimmed cases. Their E-Z and Accu trimmers look like they index off the rim face, their others index off the case base. I just talked to their Technician & he is not concerned with rim thickness of rimmed cartridges, telling me "I'm splitting hairs." I mentioned that was my prerogative, not his directive. Seems the E-Z ($29) setup should work fine, but then he reports they have determined the pilot length using 1/2 SAAMI spec for the rim thickness, so the average rim thickness should work for everyone. I asked if this 'preset' pilot was adjustable at all, and he said he thought it might be, using the setscrew.

    I have about 1K WW cases, half are new. Are their other [affordable] case trimmers you could recommend for consideration? Thanks for watching.

    I use the L.E. Wilson Ultra Trimmer, it's very precise.

    Lots of Marlins!

    Never cared for the easy trimmer when doing cases in any quantity greater than 1, very tiring since you hold in your hands, at least the way I used it. The accu trimmer is the way to go, or better yet the universal trimmer with power.

    I have always measured my case length from the base to case mouth, but I understand your point. There are differences in rim thickness out there, and shooting loads with different rim thickness mixed together can effect accuracy. I really notice it in 22 Hornet.

    I have the lyman universal. Which I think is ok. Having never owned anything else I can't give a rounded opinion. The lyman has a universal case holder on it and after you get your length set it is very fast.

    +1 for the L.E. WILSON Ultimate Trimmer. You get what you pay for so I decided to pay more for one of if not the best manual trimmer out there. If I shot more I would get the Dillon powered trimmer.

    Care to explain your reasoning for caring which it indexes off of? For which cartridges is this to be used?

    35rem: Initially to standardize/trim 500 new WW .45-70 cases..then my used WW .45-70 WW brass. I'm re-evaluating my headspace & boolit design before any trimming. I see where SAAMI calls for the .45-70 rim to be .070" +0.00", -.010" thick.

    In 6 months or so, I might expect to see an AR-10 platform (.30 show up, so those cases will need attention. That's about it, for now. Thanks.

    Walstr,
    I do think you are making a mountain out of a mole hill, however, if you wish to measure from the forward face of the rim on rimmed cartridges, I believe you will need to measure and segregate your brass by rim thickness and calculate how far to trim the case body. Regarding the .45-70, I find that most brass is way short (1.85 inch as opposed to 2.1) and may not need or want any trimming. Your rimless brass will require a base to mouth measurement for sure.

    As far as case trimmers go, in my opinion, Wilson and Forster are the best; the Forster is faster to use when adapted to power operation.

    To paraphrase Ronald Reagan, the trouble with many shooting experts is not that they're ignorant; its just that they know so much that isn't so.
