I have been stock piling all primers for the last 4 or 5 years . I have amassed close to 80,000 .....25,000 being SPP ,25,000 LPP and 15,000 SRP and 15,000 LRP. Most of my purchases have been Winchester, some Federal and about 5000 SPP are CCI magnum primers. Now all I need are bullets for the large rifle(30 cal).
As far as SPP go I have about 17K federals. The current drought is a continuation of the last one, there was a brief shower last summer and I stocked up 20 k but have since used 3K
I have a bunch more CCI and S&B SPP but mostly use federals in my revolvers. I think I'm going to try some Winchesters just in case I run out of federals.
