cold weather powders

[Paul Harm]

I don't want 10K pressures and yes that is a problem. Didn't seem to have it before, but then I didn't shoot last winter [ back problems ] and my memory is so short I can't remember two winters ago. Anyway, tried again last night and the 700X loaded to 8000psi seemed ok so that's what I'll go with.

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.

I don't think chamber pressure is static, pressure measurements are taking at something close to room temperature. A shell that works fine in the summer and does not in the winter is I suspect producing a lower pressure in the cold temps. What is published as a 10K load is probably lower in single digits temperatures. I wonder if there are tests done to confirm this.

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.

dupont hand loaders guide
AA hull
1 oz lead shot
rem 209p primer
16 grs 700-x
cb110012 wad
1110 fps at 5000 psi
there are 7/8ths oz loads in same book at 4600 psi
this is way i like 700-x so much
load from 20 ga. to 10 ga.
low pressers
small amounts of powder to loads
and VERY CLEAN burning

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.
