I've been shooting 41.2 grains of reloader 16 in my 6.5 creedmoor lapua cases and Berger 140 g hybrids.
when I developed a load I was averaging 2772 FPS. I went and shot a group of 13 rounds over the Chrono and I've picked up 53 fps , 2825. The 26" Kreiger Barrel now has 474 rounds thru it. Groups oped up from .40" to about 1.1" roughly.
Should I decrease my powder charge to get back to the 2772 fps I had when it shot good? 41g to 41.4 g of reloader 16 only gave me a 6 fps spread when I developed the load so I settled at 41.2. any body see this before or have any ideas where to go from here?
