What did you learn today - Airgun related

Today I learned that buying pellets on eBay may not be such a great deal.
i was shooting way too many fliers and was thinking WTH. although I don’t normally weigh and sort pellets, I broke out the pellet scale.
Apparently an eBay seller buys lots of pellets and sorts them all out and keeps the good ones for himself and repackaged the losers to look new and resold at a great price $$
I had 10.3’s and two different types of 13.4’s mixed in the same tins….all way out of spec; as in too light or too heavy, 6 tins later I got the idea.
As I bought them 4 months ago…. Oh well.
still good for plinking.
From now on I’m sticking with the big box stores Or my most reputable trusted pellet sellers.
Today’s lesson was more pleasant.
I learned that the absolute quietest moderator on my .177 Redwolf HFT rig is the Weihrauch….. only hear the solenoid click. And I have tried every possible moderator comercially available. Sometimes silence is the best noise we can make.
