Harold, we have been able to procure 12g shells for our inventory on a regular basis. We have plenty in stock. Right now we have Fiocchi and Federal. 20g is hard to come by. We will only sell our shells for use here on our range. If you buy 100, you shoot 100. Members get a price break of $2/box. As for reloading components, I have been buying primers, wads, shot and powder for years. I even got my Spolar cranked up to load 7/8 oz 12g. I am good for years. When they said PB and 7625 were being discontinued I loaded up with 60 lbs of each. Proper Planning Prevents Piss Poor Performance!!
Heck, I even ordered 5K of the Rio primers from PR and have them for sale in the lodge. At $85/1000 I'm only making maybe $4 on each box of 1000. Sold 2K on the first day. If the rest don't sell I'll just add them to my component stash. Easy Peasy Lemon Squeezy.
