I just bought an 1899 Savage Carbine in .303 Savage, got some cases from Graf and Sons, and plenty of suitable rifle powders. Does this cartridge work with this boolit? According to my old copy of the NRA Handloading book the SAAMI Spec for OAL is only 2.520 and my sample rounds run longer. Should I look for my 311-291 instead? Can I load longer and still get reliable function? I am in the midst of California's inane 10 day waiting period or I'd just try it out myself.
