yes. especially a likelihood in recent years with component shortages. ammo manufacturers have sometimes changed powders or primers for a given line of ammo, which can change the way it may shoot in your rifle.Has anybody ever noticed large differences with accuracy with different lot #’s on factory ammo? Hoping for some actual experiences
haven't shot factory ammo in more years than I can remember. But shooting my own reloads I normally buy powder 1# cans and as such you could say I change lot numbers all the time. I can't remember the last time I had to change a load to maintain accuracy.Our PD Sniper rifles were 1/4 moa, and we confirmed our zero (and recorded) the new lot number in our log books. Never really noticed any change in accuracy or p.o.i. We used Federal Gold Medal Match 168 .308 Win. I doubt that if speaking of off the shelf hunting rifles with hunting grade ammo you would see much difference when changing lot numbers.
