[QUOTE="Pdvdh, post: 2175111, member: 4191"] I think powder ignition problems are most likely to occur with the slower burning powders in the colder temps. Use the hottest small rifle primer available is a good choice, and then maybe not a problem? My .223s fire fine in cold temps, but I'm not using H1000 in those cases. Using small payload, faster burn rate powders. Gotta conclude some do have problems. Otherwise can't imagine why would Peterson (manufacturing and selling SRP cases) would warn their customers away from them... A bad combination of primer, powder, and cold temps must be prone to powder ignition inconsistencies. I was just this week interested in, and shopping for, 22 Creedmoor SRP cases for increased primer pocket life. Decided any gain in case life wasn't worth even a single missed opportunity in the field - should a SRP fail to fire a shell normally, consistently, and to the pre-planned POI. [/QUOTE]
