And about 2400 & Win Large Primers; I use them because I assume they were hotter than everyone elses non-magnum large pistol, but milder than Magnum primers- because its labeled both std & mag loads. It seems to work just perfect for a milder 44 mag load of 16gr/2400 with a 240gr lead swc, but haven't used that load in less than 50 degree weather.

I'd be interested to know how they work in colder weather (like 20's or lower)
