Anyone ever try that CCI/Blazer brass 115gr FMJ? outdoorlimited has it on sale for $169 for 1000 rounds. Comes out to .17 a round which is about as cheap as I can find. Right now I use either 3n37 or CFE for powder in reloading and both are extremely clean burning. Those Federals are fairly clean but I wouldn't mind a bit cleaner burning. My K2p is a bit of a bear to clean the internals unlike my Sigs or my 1911's. I like to pull the trigger mech. as well as the pin after 500 rounds for cleaning and close inspection.
