No I don't use regular wads,only leather or card disks.
Its very hard to get ANY blackpowder here. I was lucky enough to be given 3.5kg of 2f a few years ago,so that's what I'm using. It does fine for 90% of what I do

One of my guns fairs bad with #4 shot. I don't use it in it. But #5,#6or #7 it's fine!
My choked 10g has taken two geese this season past 40 yds with #3 TM. 2oz on 90gns of close to 4f powder.
