I've loaded up a bunch of 300 SAUM rounds using 180gr TSX bullets and 65 grains of R-22. My groups at 100 yards are sub moa and around 2" at 200. I decided on this load for hunting and brought out the chono today to check vel. This is the first time I have chrono'd any rifle rounds. My first four rounds came out to be 2916, 2854, 2945, and 2840. I measured the powder for each case exactly to 65 grains and each bullet was seated to within a couple thousandths (the best my reloader would do).
My question is, is this a normal spread for this round. I thought they should be alot closer. And if not, what could be causing this. Thanks, John
Oh, and I might add that I have a pretty cheap chrono. Maybe this could be my problem.
