Those Mysterious Forty-fives

The cartridge reason is so strong.

1m/m difference in head space is big difference. From Steve's post, "Additionally, the Aberman gun does not have the "stepped chamber" - patented by Luger - of the Number 1 trials gun". Sounds like the head space on Aberman being a variable (or, no strict head space), could that explain it might be able to fit 1m/m longer cartridge?
