Per my post from a few years ago I'm still working on firing my Dad's 45-120. ...at least he thought that's what he owned based on his meticulous 1960's notes.
Taking his word as gospel I ordered some Bertram brass and loads. ....got tired of finding someone who could get Norma brass.
Empty brass fit just fine. Loads bottom out long. I measured the distance from the receiver face to the start of rifling, not the counter bore face. Roughly 3.28". The cartridge is about .68" long, measures 3.65" long.
Clearly the gun is chambered for a shorter cartridge. Please help and tell me the correct size.
Thanks, Dave
