OK - I will apologise for starting a new thread on this but I just couldn't figure out which of the fifteen thousand and twenty three existing discussions that lead into this to comment on.

I just took my new to me No4 Mk1 to the range and put 40 rounds of PPU ammo through it, placing an o-ring on each case. My question is should I be concerned about how tight the bolt is to lock, when chambering the round? Whilst I didn't have to stand on it, it was firmer than I would have expected.

I haven't had a chance to reload these cases and try the 'fit' yet and probably won't for a few weeks.
