I use the Hornady trimmer and after trimming I measure the cases with my caliper. I don't get the same case length every time.
It's supposed to be a simple operation- you take a reference case, you lock it in the trimmer and set the length of trimming for the rest of the cases. then you put in the shell holder the next case and trimm it to the set length (i.e. until metal shavings stop to fly). chamfer&deburr. period. you repeat it for all other cases.
what am I doing wrong to get 1-2thau of a difference between cases? Sorry guys, I know this is trivial operation. But even a trivial operation can be performed in a wrong way. Yes, I know I can have a shitty caliper and measure the cases in a wrong way. So, what would be the correct way then.
