Yesterday FedEx delivered two 1000 bricks of 209 primers. They are Cheddite. I had forgotten that I put them on backorder almost a year ago. Loaded a couple up in Remington STS went out back and shot them. Work fine. They are a little tight going in but come out just fine. I suspect that whatever shells I reload with them will only take Cheddites from then on because they are a thousandth or so wider than US made primers.
