I tried to use the search to no avail.
Have you experienced any significant vertical deviation with all the different low cost/surplus/Russian ammo?
I shot a two inch, 10 shot group at 50 yards yesterday and then had about a 5 inch vertical shift with some other steel cased ammo.
I mix all my ammo together, so I am not sure which was which.
I understand minute of man and all of that. I am just trying to understand what is realistic under real world conditions.
Thanks
