Today when I was shooting my M1A it has some minor trigger work an ultimak scout rail a 7x scout scope everything else is stock. I was getting 3-4" groups at 100 yards with wolf WPA like this one


then this happened with out the flyer this would be 1"


then this happened I think this would be about 1" maybe a little over


I'm assuming this is a fluke. Does this happen to anyone else? I am new to the M1A maybe 200 rounds through it so far. Is it normal for groups to vary this much? Thanks for your input.
