Small rifle primers in 6.5 CM

[bowrunner81]

There are plenty on Federal SR match primers available around me, and I am going to use them in a 6.5 creedmoor. I have read there is hesitation taking them down to low temps. My question is has anyone tested this down to some lower temps. Say 10 degrees. I have some large rifle primers I can use for hunting and take the small rifle primers out for practice if low temps are an issue with small rifle primers.

Thanks!

I use Lapua 6.5 CM small primer brass down to 10° and colder and have not had any problems.

See the thread below. I’ve left a clip out overnight at around 20 below and then shot it. It is common and I routinely hunt around +/-0.

Ball powders and SRP do not play well in colder temps. A buddy had issues with superformance and srp and I experienced some delayed ignition with staball 6.5 in -16 C. Both with alpha srp brass and cci 450’s. I haven’t noticed any issues with H4350 in colder temps so far, but haven’t shot it in the real cold yet.
