Hello,
I’ve got one, had it about 2 years. Bought it new.
it was a bit ‘Jammy’ straight out of the box but me trying all sorts of different cartridges didn’t help. It didn’t like Eley extra longs 3” as it would pull the brass off the case as fired and leave the plastic case in the chamber.😱so I stripped it down and gave the chamber a good polish and the mechanism a good oil and light grease. Then bought a slab of 3” Winchester’s and shot the lot on clays and pigeons on the same weekend. Then another good clean and oil/ grease up and now it cycles anything 3”, and some of the 2,1/2”
