I have a pile of the Hornady brass thanks to people leaving it at the range, once-fired, and additionally I have a lot of the Lapua small rifle primer brass. For large rifle primers I used CCI 200 primers, and for the small rifle I've used both the CCI 450 and Ginex NATO primer. I cannot say I've ever noticed it hard to keep a single digit SD assuming the powder and bullet were agreeable to the barrel.What brass are you guys using for your 65cm? Brand and primer size?
For pickup Hornady brass I simply do my normal case prep, and I anneal it so I can then track annealing every other firing.
The small rifle brass gets cratered due to the R700 firing pin, and I've not had it bushed. Granted it's mostly a cosmetic thing at this point.
