just spoken to the club member, the reason he couldn't seat bullets in two of the chambers, was due to a bit of lead in each of them. Seems using too heavy a load does something to the hollow base of these bullets and breaks them off.

he is using Fiochi primers which are difficult to remove, will try his CCI next time and 3 grns of powder instead of 4

as for the indexing failing on 2 chambers, keeping the spindle cleaned and lubed and firmly pulling the hammer back cures it
