Question on reloading the 45-70 cartridge for my new Marlin 1895, my first rifle cartridge I’ll be reloading for (I have a Dillon SDB for all my pistol cartridges and MEC 9000 for shotgunning).
Just picked up the rifle a few weeks ago, and shot some Rem. 405 JSP rounds through it. In the next week or so I’ll be picking up a Lee Classic Cast press and all the other items needed to reload this round. My questions relates to the fact this is a straight walled case vs. a bottleneck case.
I measured the case length of some of the fired Remington 45-70 cases and they were well within the max case length spec in my Lyman manual. In fact, they really didn’t lengthen much as compared to the unfired rounds. In general, do straight walled rifle cases expand like bottleneck cases such as the .223 rounds I shoot through my Rem. 700 SPS Tac (which I’ve also measured, and indeed they do lengthen after firing)? Are 45-70 cases similar to straight walled pistol cases?
Also, since the case mouth is expanded during the reloading process, does one need to chamfer the case mouth similar to bottleneck cases? I’ll be reloading some 300 LFP bullets at powderpuff velocities (900 – 1200 fps) for punching paper. Thanks!
