Hi all
Just got a new 2019 B525 12G Invector+ & I noticed when cleaning it it took me about 8 felt pads before I stopped seeing kak on the cotton.
With my old Miroku 7000 I usually spray napier cleaner in the barrels, drink some coffee, then bronze brush them a few times followed by cotton pads x 3, but with the 525 I just could not get it clean, I then tried Britbore mops which were better but still took 4 runs thru and 2 mops used per barrel after which a check with a clean cotton pad pushed thru still showed some kak. I've used Eley fibre wad Olympics in both B525 and Miroku 7000.
Is it down to the backboring allowing more kak to pass the wad at ignition ?
cheers endo
