I have the Luxano. Have put around 500 carts through it since new, all Hull Comp X 28g Fibre 7.5 for clays. These are only 65mm in length, but I have only had about 5 jams on the 2nd shot, so around 1%. Not sure if this is because the gun is new or the cartridge is short ?
I was reccommended the Hull Comp X by the dealer I bought the gun from, and I like the price (£3.60 a box if you buy 500) and they are low recoil and clean.
I was in my local dealer today, and he recommended Eley Blues, which are 70mm cases, but £4.25 a box.
I would prefer to use a cartrgide that does'nt Jam at
