Magnum Man,

Thanks for all the info. Yeah, I wouldn't worry about the temperature deal for typical pronghorn hunting, in fact I use some relatively temp-sensitive powders when after prairie goats myself. Last year Eileen got hers on a morning around 20 degrees, but that was exceptional�and the range was only 150 yards anyway. (She and I each have two tags this year, so will be after them pretty hard.)

Have you tried the short-cut version of 7828? I've been using it in various rounds for the past couple-three years and it seems to work exactly the same, but a little more will fit under bullets in some cartridges--and the .243 with 100-grain bullets would be one.

Good hunting,
