Wow! Those suckers are really moving out with 130 grains. Chrono readings look about right. A five shot group of 300 GDs and 80 grains weight (103 grains volume) gives me an average of 1755 fps over my ProChrono (with Harvester short sabots).

Funny thing is I've been looking through my records and find I've never gone over 110 grains volume with T-7 and 300 grain GD's. Guess I have more homework to do.
