I reloaded some 150 gr Winchester PPFN bullets today. Using Win 748 I loaded up 10 at 34 gr, 10 at 35 gr, 10 at 36 gr, 10 at 37 gr and 10 at 38 gr based on info in the Hornady Handbook. This filled up my 50 cartridge box and now I'm ready to head to the range for testing. My main goal is accurracy, so I'll see which load shoots best. Is this an acceptable procedure? Should I load and test more than 10 of each? How do you guys go about testing loads?
