Pleasant Surprise

Previously mentioned how dirty my x twist Barrel was. I had been shooting Mark 2s and the 25 grain JSB. A week or so ago I received 6000 pellets (20 tins that is) Mark 2s and 25g. I mentioned that they look like they were waxed. I sorted all 6000 of pellets. Pleasantly, after shooting about 600 pellets I cleaned my Barrel. I have no chips, flakes, chunks, slivers. I do have some lead powder. Of course!
I have 20 more tins coming in today. I will open them and see if I think they're waxed also. I will not sort tihem yet. I'm a little Punch-Drunk on the 1st 6000.
Anyone else have similar results?
 
Have noted that the 2018 box of pellets that I received two weeks ago was exceptionally clean and seemed to have a different coating on them, they look really promising, will have to wash a tin and shoot them washed vs unwashed, but I can confirm that the new batch is probably the best batch os JSB that I have ever seen as far as cleanliness and visible flaking on the inside of the skirt .
