BP just raised the price of Cheddite Primers

[Double Lab]

Ched. 209 CB 0175-12 15.9 7200 PSI 1,150

Win. 209 CB 0175-12 16.1 7500 PSI 1,150

Here's the exact load I'm using with Clays. Actually pressures are lower with the Ched. primers taken directly from the Hodgdon site. I've always believed that to be the case.

Seems there is a significant difference with heavier loads.

12ga Remington STS, Nitro 27,

Cheddite 209, 15.8 gr Titewad, AA Wad, 1 1/8 oz, 1145 fps 11,400 psi

Win 209, 15.4 gr Titewad, AA Wad, 1 1/8 oz, 1090 fps, 8700 psi


12ga AA

Cheddite 209, 17.3 gr Clays, AA Wad, 1 1/8 oz, 1145 fps, 10,700 psi

Win 209, 17.2 gr Clays, AA Wad, 1 1/8 oz, 1145 fps, 8800 psi

Tightwad is a powder that really does well with payloads from 3/4-1oz. It's a fast burn powder and doesn't give it's best performance or lowest pressure with heavier 1 1/8oz loads.

Cheddites are what's available right now and I've always found that they give similar or lower pressures in the majority of loads when compared with WW209's. Burn rates and payloads are the key factors.

I agree, but it is still a 2700 psi increase with Titewad with a Cheddite primer over a Win 209 with a heavier 1 1/8 oz load, 1900 psi more using Clays for 1 1/8.

They do seem to be on par pressure wise with lighter loadings. With heavier hunting loads I will treat them as a magnum primer and go down 1 bushing.

Been interchangeably using my primers for decades without an issue. REM-Win-CCI-Rio or Cheddite-Nobel-Fiocchi if Euro-sized primers are needed. Never had a pressure issue. A few bloopers from bumping my powder hopper but otherwise all the shells break targets or take game. We’re no where near loading near max for our shells so any difference is negligible. If Cheddites are available use them. Just remember you can’t go back to domestic size primers in those hulls.

I just bought a box of a 1000 at local reloading store, $47.......

Never used cheddite primers before, I guess I'll see how they do.... As it's all they had.

I asked about Large Rifle primers, they just chuckled.... Last time they got a shipment of LR primers, was March of 2019...... I am down to my last 100 of those.... And, I have a wyoming antelope hunt I need to get some practice for my wife... She better learn to hit that 300 yd antelope fast.

When I first started trying the Cheddercheeserite primers I loaded a few shot them in the snail then loaded WIN 209 tapped them hard on the table top to see if they jar/vibrate out .And they stayed in fine , so I fired them with no strange sounds . Did that with 10-12-16-20-28 and 410 didn’t try them in the 8’s but if I had no issue with ALL the lesser gauges I wouldn’t think primer pockets would be an issue .
