Magnum primers for Bullseye??

I'm a very long time reloader and bullseye shooter. I've never heard of anybody using magnum pistol primers in a bullseye load, but since that is all I can find right now I am considering doing it in my 45. Our loads (4.3 of Bullseye) are pretty low pressure, so I don't think that would be a problem. Affect on accuracy is unknown. Anybody have any experience with this?

I've been using Winchester LP primers for years without an issue.

I have been only using cci magnums for past half year, first by mistake, secondly out of necessity due to lack of availability.

From my research they work fine in bullseye loads, I would not use in loads that are at or close to the maximum load for your combination.

My experience parallels everyone else. I'm only using them for mild Bullseye loads, but the accuracy stays the same. So far I've used Federal & CCI magnum large pistol.
