cold weather powders

[10 bore]

[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.

Here are a couple of pertinent articles.

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

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.

but ,at the time this data was printed it was Dupont still

Years ago, DuPont published a load for 1 oz of shot and 800X powder. It was OK in warm weather, but nasty in cold weather. I questioned DuPont about it, and they said "Oops, we shouldn't have put that load in the book". I threw away about a half a case of those shells

800-x is made for the heaver loads and smaller gage guns. i don't think i have seen a 1 oz 800-x load in 12 ga.???
