I’ve some primers mixed up of the same colour

[BiggameBesser]

Is there any way of telling the difference between a large rifle primer and a magnum primer if they are the same colours

Is it dangerous to shoot a magnum primer in a .243 or a .308

Check for the coloring inside the primer.

No danger, might be slightly different FPS. Keep it in normal load range and you will be fine. Magnum primers handle pressure better. Use it as range ammo.

Are they Federal by chance?
Chemical fill of Fed Mag primers (215 & 215M) is purple. Chemical fill of LR (210 & 210M) is red.
CCI uses yellow for both LR and LRM.
I don't remember what Win and R-P colors are.

In the future, avoid mixing primers. Keep LR and LRM separate, and in their respective boxes. Only take one box out of the cabinet at a time. Keep records. While they should both be safe, I bet your ES/SD will climb by quite a bit.
