Probably a dumb question but that's mainly the type I ask. Dug out the press after not using it for a while. Turns out I had left some primers in the feeder (yeah, I know). Any way to figure out which type they are? I can't remember what I loaded up last. They LOOK like large pistol or rifle but I don't know how to tell them apart. Any savants out there?

Get out a box and look. Its easy to eyeball the size. You could also measure them and a primer pocket if you dont have an unopened box

Large vs. small primers are pretty easy to pick out, but good luck if you're trying to determine large rifle vs. large pistol, & small rifle vs. small pistol!

pistol primers use thinner metal than rifle primers

I just did some measuring. Here are the results:
CCI 550 small pistol magnum- .1749" and the inside looked yellow.
REM 5 1/2 sp- .17485" green
REM 7 1/2 small rifle- .1755" orange.
FED 205 sr - .175" purple
WIN Large pistol- .209" gold
CCI 300 LP- .2106" yellow
FED 210 Large rifle- .2106" red
CCI BR2 LR- .2109" yellow
I have others but I figure this should cover it pretty well.

And if you are still unsure of what they are, Pitch them. That would be like throwing away hen's teeth, unicorn horns, or Bigfoot hair. You just can't find 'em now. Thanks guys -

Thanks guys - Eyeballs, fingers, hands are also pretty hard to replace as well. If I was not 100% certain they would be disposed of. It just isn't worth the risk of damaging yourself, somebody else, or your firearm.

all small are the same depth , and have same payload , just thicker or thinner cup metal
large , rifle are deeper I measured a .007 difference from large pistol rifle pockets are deeper
what are you trying to load if it is low pressure target ammo use them up if your going for top velocity high pressure hunting loads in a rifle set them aside labeled unknown and use them for something else
as an example I load some cast boolit rounds for 30-30 that are well below max pistol pressures unknown primers would be perfect for that
like wise my 38spl plinking loads are no where near top velocity and wouldn't suffer from a mix of small rifle and pistol primers
but I sure wouldn't put together my hunting load in 308 without knowing the components for sure as I am running just shy of book max and worked up to it

If you put a pistol primer in a firearm like an ar you run the risk of slam fires with the free floating firing pin. Your not going to damage anything. A pistol primer in a rifle cartridge MAY not light it as completely and you MAY get a significant enough decrease in velocity causing you to miss. A rifle primer in a pistol MAY not fire and it MAY increase pressure SLIGHTLY. Not enough to damage the firearm. You will see over pressure signs.

the pistol primer can't take the 58Kpsi on a standard rifle round like 223 and may rupture they are max out around 35Kpsi ruptured primers are bad news it sends gas back down the firing pin channel if you put a rifle primer in a pistol you won't be over the capabilities of the cup to hold the pressure.

How many we talking here?
Cup thickness is going to be about the only possible indicator... and that's a dicey proposition.
As others have noted, you can "get away" with rifle primers in pistol rounds but vice versa is a BIG gamble.
Depending on where/how you stored the press with the primers sitting in it, they may not be in the best shape anyway.

If it were me, and I had developed a load below max, I'd just run the primers into some pistol ammo and set them aside for plinking, marked as such. You might get some light primer strikes that cause a failure-to-fire scenario because of a thicker cup, but at least you would know why it happened and could still save the powder, bullet, and case.

Drop them in a small can of oil, then pitch them.

Did some more measuring. This time for depth.
CCI BR2- .127"
Fed 210- .1289"
Win LR- .1272"
CCI 300- .1195"
Win LP- .1183"
Fed 150- .1194"
These numbers seem to be a bit more telling. If you need the numbers for small rifle vs small pistol let me know. If you are still unsure just treat them as pistol primers. One word of caution is that rifle primers will be harder and if you have a week firing pin spring it may take a couple tries to get them to go off.
