How can ya tell? Visual clues to boxer vs berdan?

So I've been buying up some 7.62 from auctions lately, and in a lot of the cases research shows that a particular ammo can be either/or when it came to production. What, if any, visual clues are there to determine one from the other? I'm willing to pay a tic more for boxer stuff since I reload, to others it probably only matters if it's corrosive or not. If there is a hard and fast rule beyond "X" always used berdan but "Y" always used boxer" I've never heard. Just curious if there are strong clues to what something might have been primed with, so that I can apply my own value to what I happen to be looking at potentially bidding on.

TIA...

Hard to tell without shining a light in the case. Most berdan primed brass have a crimped primer, but that can be misleading.

Headstamps can tell you a lot, all the Port ammo (FNM, BF) is berdan primed. So is all the SA ammo, Aussie AD and British RG. LC will always be boxer primed.

Not so.

Some RG headstamped ammo is Boxer Primed.

Berdan and Boxer primers (rifle) are different in diameter. Most rifle ammunition with Berdan primers has primers ranging from 0.217 to 0.254" diameter.

For example, most .303 Brit runs around 0.250-254" and most 7.62x39mm runs around 0.250". This size difference (from 0.210") is usually big enough to tell just by looking at the primer, especially if you have a Boxer primed case at hand for the comparison.

I should also mention that there have been Berdan primers made with even different diameters, but they're not as common...

Berdan primers are slightly bigger as mentioned above.
