Changing primer improved accuracy by 1.5MOA is that even possible?

[QUOTE="Greyfox, post: 1735455, member: 10291"] I haven’t used Winchester primers for several years, but I recall that they were labeled for std “and” magnum use. Interestingly, they produced similar velocity and accuracy to the Fed210M’s and BR2 in my 308’s. Of late, I have found that my primer changes will generally effect ES/SD more so then group size. Given your velocities are comparable, I wouldn’t not rule out the 1.5MOA improvement with the switch, but would be suspect that something else is going on. I have not seen changes that great due to a primer change that produced the same MV. [/QUOTE]
