With hunting rifles only the 17 Rem gets the Rem 7&1/2. With my shooting I can't tell a difference with match primers in a hunting rifle. Might be a different story if I was a benchrester. But I have seen significant differences between standard and magnum primers in more than a couple of different loads.
One of the handloader digests from years ago was titled something like accuracy by the inch where a guy documented each step in his quest for accurizing a 222 varmint model 700. Although primers were way down the list they did take a couple of tenths off the average group size. He got down to a consistent 0.2 - 0.3 groupings with a factory rifle which is impressive.
"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
