Pond, James Pond · April 17, 2014, 10:27 AM

I normally buy Fiocchi primers for both my .38spl needs and my .44s (Mag and Spl). However, supplies are not alway available and so I might need to buy what is there.

This happened today and I now have 200 of both CCI No.300 and No.500.

I have heard that if you change a component, you should redo load work ups. For powders and bullets of course. For cases I might not bother, but for primers I am not sure.

My .38s are pretty mild and so I am not so concerned there, however, with my .44s, they are quite hot in the case of the 240gr FMJs I have.

Basically has anyone used Fiocchi Standard Pistol Primers (particularly Large Pistol) as well as CCI No.300 and can you tell me if they produce similar or wildly different results?

I'd really rather not have to redo load work-ups just because this country has poor supplies of stuff....
