I could count on less than 2 hands the number of sub 30 degree days during deer season over the last 5 years.

I run Federal 205Match primers in all of my SRP cases, this includes 22-250, 22-250AI, 260AI and 2 6.5x47's. Never had an issue in any of them.
The only time you NEED a magnum primer is with really cold temps running ball powder.
Cheers.

Winter before last was brutal. Single digits quite a few days and in the teens and 20s others. I had a cheaper Vortex scope that went into whiteout. This winter was unusually mild.
Anyone use the small magnum for 6.5 Grendel or 25-45 Sharps? Just don't want to get them for 120 federal pieces of brass.

I'm using them in all my SRP brass.

Christmas Eve, I was cooking a pig in it. That's the coldest 3 days we've had in decades.
I like to be better safe on the one day it might be cold and it does not fire on the buck of a lifetime.

I use CCI 41's with extruded powders in my 6.5 CM, Federal brass, 1X fired, cheap.
For ball powders I use the Rem 7 1/2 primer. A good load is 123 H ELDM with 44.5 Staball 6.5
More info:
Look at table 1 and see how the Rem 7 1/2 compares with other small rifle primers - primer blast waves measured in k Pascals. Blast waves from Rem 7 1/2's are much higher than other SRP's & approach that of LRP's. CCI 41's gave erratic results when used with max charges of RS Hunter.

I have been running cci400 in 6.5cm for several years now in N. Idaho with no issues ever.
I was concerned as well In the beginning and even through a few in the freezer for a couple days to test and had zero problems.
Load is with RL 16 under a barns 127 LRX OR a H 143 ELDX. AND LAPUA brass

The only issue I have had with small rifle primers has not been ignition but with cup thickness. CCi 450's, CCI 41's or Rem 71/2 seem fine. Others have cratered and on occasion "blanked" the primer with 55k + loads. Bushing firing pin eliminated this issue. Rem 700 action and one M70. (6mmBR) Having said that, I do not live in the artic but I due insure the bolts on my hunting guns are clean and dry before each season.
