Hatsan Escort strip clean and rebuild part 1

My attempt at filming and uploading a how to vid on the Hatsan Escort (new type). +++++++ update: firing 30 gram + cartridges through it the choke would come lose in about 5 shots. I was using some 32grm Eley HV shells over some stubble, emptied the escort at a pigeon, the 3rd shot was very dirty, so i checked the choke (which was tight when i loaded) and discovered to my horror that half the choke was gone and i had a bulge in the end of the barrel where a no. 6 had got up behind the chok
