I'm a new member and will post an introduction in the proper place, if necessary, but have been following this thread with interest. My experience reloading is limited to just the last couple of years, and there are questions aplenty. To get to it...recently I inherited a pile of my Dad's old reloads. Old as in late seventies.
The cartridges that I have a question about are .30-30, a mixed bag of R-P and Win brass. Once dis-assembled, I sorted the headstamps and measured the cases. Out of 60 cases, one measured 2.040", one 2.030", and all the rest were consistently 2.024" +/- a negligible amount. No idea how many firings they've seen.
All this got me curious, so I measured some factory .30-30 ammo I have on hand. The Rem 170gr 'Core-Lokt' cases measure 2.020". The Win 150gr 'Powerpoint' cases measure 2.026".
What are the published trim-to lengths based on? Speer, Lyman, and Lee all have different lengths for this cartridge in their loading manuals, but all are over 2.028".
