300WSM primer question
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
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?
