I bought 1000 pulled Surplus 55gr FMJ's about a year ago. I got the bug to go ahead an weight them for deviation in weight!! Boy was I surprised. I guess maybe I'm spoiled by using quality bullets and being picky on my casting. No wonder the required accuracy for the M16 was 4 MOA at 100 meters! My deviation of the about 700 bullets left was anywhere from 54.0gr all the way up to 55.9 gr. Add this to the powder deviations guarenteed in mass loaded ammo an it's no surprise they couldn't get better then 4 MOA. To me I will not put up with any deviation on commercial bullet of more then +/- .3 gr ! If I get more then that I will not buy those bullets again. Example Privi 198 gr FMJBT I had zero deviation, Nosler BT's again zero to .1gr etc. My cast bullets I keep to the +/- .3 gr Max.
