BP just raised the price of Cheddite Primers

[J.B. Books]

The Hodgdon Reloading Data Center is now showing recipes using Cheddite primers. I had read and believed they were similar to Win 209's for pressure. If you compare like loads on the Hodgdon site you will see a significant increase in pressure over the same load using a Win 209. It turns out they are more like Federal 209A or CCI 209 Magnums and should be treated as such by those who are trying to keep pressure low.

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.
