I did a ladder test a few weeks ago and decided to load 4 5round groups ranging from 35.8gr of IMR4895 to 36.4 gr going up in .4gr increments. I forgot the magazines, so they were single loaded. If I remember the velocity from the load test, it should be somewhere in the 2250fps range.
Springfield Armory M1A, 3x9 scope set at 9x from bags at 100 yards. Wind was gusty up to about 15mph coming straight towards me.
