hi all
my no4 mk1 ROF has an A suffix on the mag and the rifle serial # and it will not load correctly if you use the _-_-_ method or even -_-_-... the only way it loads without a rim jamb is to load ///// with each rim in front of the lower one...
now before you say I am doing it wrong I have loaded others with the up/down without a problem
strange things can happen in rifles built in war times.
