Can someone tell me what primer size is prefered.
I have some Remington factory rounds with LP primers. I didn't know they came with both sizes.
Thanks,

Most prefer the LP primers because that is what they are used to and set up for.

I doubt you can find any reduction or improvement in accuracy either way.

The reason that you find the small primers in some rounds is because they use a reduced lead or lead free priming compound for those places with lead restrictions.

Paul,
Thanks for the reply. I bought a 1,000 SP primers, not knowing they came both ways.
Thanks again.
