The .35 Rem cartridge diagram in my reloading books show OAL of 2.525". I pulled one cartridge from three Remington factory boxes on hand and measured them. Since one showed longer, I pulled two more from that box.
Box 1: 2.514"
Box 2: 2.518", 2.521", 2.522"
Box 3: 2.507"
My caliper’s battery is dead. I’ve only got crude items like rulers and tape measures handy at the moment.
I can take some pictures of the box, but I’ve never figured out how to post pics on this site through my phone
