Magnum Primers needed???

[L. Cooper]

Not much real information from me in this one, but I use Magnum primers in my .300 Win and regular in the rest of my rifles. I started to work the loads for the .300 with magnums because that was what my loading manuals had used, and although lots of components have been tried, I haven't got around to experimenting with primers to compare them.

I also have not noticed any problem with either standard primers or magnums and cold, although all my really cold shooting has been done at game so my statistical sample isn't really that big. I just can't get motivated to go to the range when it's -25 or -30, but I will call coyotes or hunt deer at those temperatures.

Even when cartridges with standard primers are very cold, the gun has always gone "bang", and lots of animals have ended up shot (and some seemed just severely frightened. Hmmm.... should I blame my shooting or my primers?).

One day I will have so much time on my hands that I'll try some actual chronographing in extreme cold. Maybe.
