Is there a chart somewhere about primer substitution?

I am wondering if I can substitute a Fed 210 for a CCI 250?

Thanks!

There are no charts that I’m aware of. You can substitute those primers but there is no guaranty that the load will shoot the same. I found that if you go with a 210 (larger rifle) instead of the 250 (magnum rifle) the group size and impact location changes.

It is a Fed GM210M that I have, not a Fed 210. I wrote it wrong before.

GM210M or Federal 210 (regular primer). There isn’t much difference between the two.

Thanks!
