Never measured one. I used Winchester primers in the past when Federals weren't available. They worked great.
Thanks Butch. I guess I've lived a sheltered life or just plain not paid attention (which is probably the case here) , as I was on a site the other day and it had Winchester small rifle primers, and Winchester small rifle "Match" primers. I didn't know Winchester even made a "match" small primer. WD
dont forget rem 7.5 they shot as good as anything just too much aboiut them bull snever measured one. I used winchester primers in the past when federals weren't available. They worked great.
I didn’t either
vick swindelhurst used win primers for years and shot wellwinchester responded via email that these are indeed match primers. They have the same dimensions as the sr primers. The difference is they have a specific priming compound that provides better ignition and shot to shot consistency. And they are currently producing and shipping them to distributors. Again.... Fwiw.
