Nothing like a good clean pellet I always say!
Oh, you mean those felt thingies Beeman sells? Yep, I have a box somewhere that I bought 12 years ago. I tried them, but they just didn't seem worth the cost for what they did. It's just cheaper and more effective to use clean cotton patches pulled through the bore with fishing line. First one or two with Goo-Gone on them, then a couple more to clean that out. But I must admit, I don't clean the bores on my airguns very often.
BTW - When I shot PCP a lot, I DID clean my pellets. Actually, I sprayed them with a lube that cleaned and lubricated them, then used an old towel to remove the excess.
