I had loads worked up for my modified .243 that would cut 1/3" groups at 100 yards all day long.

I switched out the primers for CCIs one day because my gunshop was out of the ones I normally used (Federal).

Groups opened up to well over an inch.

When I went back to Federals, my groups shrank back to where they should have been.
