cold weather powders

[J.B. Books]

Here are a couple of pertinent articles.

The Curmudgeon at Ballistic Products says to increase pressure in cold weather.

[QUOTE=Pete Lester;155506]What were the pressures of the non 700-x loads, were they real low like 6 or 5K? I don't believe it's the 700-x making the difference, it's because it's a higher pressure than what you had been shooting.

in the 12 ga my 700-x loads are from 5000 psi to 6500 psi and they seem to shoot just fine. i shot 6 rounds of trap and skeet on new years day at 13 to 20 degree temps. i had 1 bad shell and i think i tried to get one to many loads out of it, the crimp was not tight. i like 700-x and i have had good luck with it for the last 40 years. i load STS and win AA hulls maybe that's better to load with for that type of powder???

What are the component combinations? I was looking at the IMR reloading center and they have 3/4 and 1 ounce loads in 12ga but no 7/8 loadings which is really weird. All the 3/4 ounce loads with 700-X with AA hull in 12ga were 7700 psi and up.

Are you using the Remington STS primer? The same load (14.5) grains with a Win 209 producing 7400 psi. Not sure what the Fio 616 does, no data listed for it. I have not used Remington STS very much, they are I believe the coolest of all primers.

Hard to know for sure what is going on when data for the same components is different.

I would think the makers of the powder ,Dupont would be the ones i would trust more. pressures so low on all loads its not a problem.

Hogdon bought out Dupont in 2003, that is why the 700-x data is on their website reloading data center.
