Re: .308 190 SMK Reloading Data
I had to get into my old notebooks. I keep all my load development targets in the book and make notes about the conditions , etc, right on the target. I found that I did try the IMR-4064 and the rifle didn't like my loads. Now for the funny part - I checked a worksheet I had put together for the Varget load and found that my numbers matched yours identically. A fifty shot sudy group had an average velocity of 2530.92 FPS. I had a larger standard deviation than I would have liked with the load (SDEV = 17 FPS), but I like the way it punches paper downrange. I found that the .308 doesn't launch the 190 SMK with enough velocity to use it for a hunting round, but it is hard to beat for the money for competition.
Attitude is EVERYTHING!
