    Gentlemen!
    I have a quick question for you... I was loading for my 300 WSM in the fall for the local white tail season. had a good load worked up for the season, and figured I would run with it.
    The load is as follows:
    Federal brass fired once
    Winchester WLRM primers
    61 grns of H4350
    OAL 2.885

    My question to you is this, are Winchester primers temperature sensitive?

    Reason I ask, I got lined up on one, pulled the trigger and pop!
    Figured it was a "one time thing" and chambered another round. Same thing!

    Now I'm pissed and Bambi is running into the bush... gone.

    So I chambered and fired another three with the same results.

    When I worked up the load, it was around the +10c area... when hunting, on the day it was -20c. Is this my problem?

    I can't answer the question about temperature because I have never shot in -20c, but I have had some WLRM primer do the same thing that you had happen to you.

    I purchased 1000 primer from a gun shop at a reduced price.The gun shop had bought them from a store that went out of business. I don't know how old the primer were but they must have been 15-20 years old. I have had a number of them fail to fire.

    I have never had a fresh WLRM primer fail to fire, but again I have not shot them in very cold conditions.
