Re: bedding question/Primer Question
Hi, living in Canada, I have to contend with cooler weather so primers make a difference. So far, I have only used the Fed 215M primers so I don't have to worry about temp.
I guess it depends on how cold you mean. If not going much below freezing, the Fed 210 should be ok (test first of course). If you are planning some really cold hunts, stick to the 215. The statistics will not impress an animal and the the hangfire/misfire will definitely get your attention.
Try the match 215 primers. It may get you the same deviation and you will not have to worry about the temp.
I have found the H4831SC extreme to be temp. insensitive and my loads work in all climates I hunt. Drop tables don't change much either.
