Are the ones that are to short making contact with the cutter? I rock the brass around in there a bit and all of mine are within 002 Link to comment Share on other sites More sharing options...

But I use this mostly for plinking ammo and SHTF ammo. Does the job and will hold MOA at 100-200 yards with a 55g bullet. Gotta widen your level of acceptability when using something like this. You’re introducing a lot of human error to the process. Link to comment Share on other sites More sharing options...
soflarick Posted February 23, 2021 Share Posted February 23, 2021 Same case brand/year, or random cases? That has an effect on the results because of alloy and neck thickness not being consistent among manufacturers. I rotate the case while pressing into the trimmer, then every so often run a q-tip through the case holder to clean off any debris or layer of schmutz that accumulated. I get pretty consistent results. Link to comment Share on other sites More sharing options...
NuJudge Posted March 14, 2021 Share Posted March 14, 2021 I have one of the table-top Giraud units, which I use in several calibers, and I got such variations until I added a twist to the case, before withdrawing it. I would suggest calling Mr. Giraud and talking to him about the issue you are having. All the issues I had with the table-top trimmer, he was aware of and told me how to deal with them.

427Cobra Posted May 2, 2021 Share Posted May 2, 2021 The old non uniform trim length, it doesn't matter accuracy wise. I have used my Giraud for 10 years, it indexes off the shoulder, so consistent trim lengths are achieved by consistent bumping of the shoulder, I set my trim length .010 from end of chamber, my 308 trim length is 2.025, 223/556 is 1.765, stop worrying about trim length, its not what causing your misses.
