Grendel at 600 and 1,000 yards

I used different increments and had different results, but the specifics aren't too important to the data I've taken myself under my tolerances. An interesting thing I noticed from shooting on the east coast and west coast is max load variances. I figured that in Wyoming, the air was dryer so the propellant burned faster than it would on the east coast where our air has about 65% humidity so the load is a bit "damper" slowing down the burn rate. This is the only reason I can think of as to why my 5.56 loads a few years ago were so far off (maybe 3 grains due to overpressure with some powders) than what I had previously recorded.
