the CCI primers are as cheap as you will find them anywhere,,since the Fed 205s are unobtainable I did a primer test with my 6PPC and I get better ES and accuracy with the Win WSR primers than either CCI`s and actually as good and maybe better than the 205`s,,I shoot CCI 450`s in all my 6BR ,6 BRDX and 6.5x47L loads and the Win WSR in my 6PPC
30$ a 1000 for 450s is the new best going rate and if you have to have the BR primers and see them for much under 50$$ you will be lucky,,
the Win WSR and CCI 400s for 28$$ is as cheap of primers as you will find for AR loads unless you like the Tula or S&B`s
for my use the Win WSR and CCI 450`s will keep me covered ,,I have lost count the last 18 months but have filled 2 quart jars with spent small rifle primers and havent used over 4-500 large primers and those were just for deer rifles and a few 243s for my 1,000 yard load..
good to see all that powder in stock,,powdervalley has a good stock also and my LGS has been keeping plenty lately,,
