Looking for 20ga Hulls

I thought about posting this in the trap shed, but I also want to know if anyone knows of anywhere that they are in stock to order them. New/once fired, I don't care. Need to be 2 3/4".

I found this on gun broker

Ballistic Products would be worth a look.

I own a sporting goods store. I’ll check suppliers and see what I can find for ya tomorrow.

Been sold out for awhile.

find a local gun club/sporting clay/skeet outfit. There will be a higher percent of 20 ga at sporting clays or skeet places than at trap places, at least that has been my experience.
I shoot sporting clays and there are drums full of shot shells tossed out every week there.
I'm sure that they would let you go thru and load up on 20 ga shells.
