Not at all.
But a lot of folks don’t realize how many short magnums there really are.
The 6.5 PRC is overtaking the 7 Rem mag as the favored hunting magnum, the Sherman Shorts are enjoying a wildcatters’ Renaissance, and lots of folks are shooting the WSM’s and RSAUM’s in long range tactical matches (not PRS/NRL, but team and tactical matches with slightly different formats and expectations). The Ruger Compact Magnums didn’t really take off - with the exception of the 6.5 PRC - but the availability of rifles and brass had a lot to do with that.
In general, the world isn’t hunting as much as it used to, so there’s less and less practical use every year for any magnum, and no short mag plays in ELR (where BIG magnums and super magnums have taken a firm new market foothold in the last 3 years), so the magnum market is small. But I can tell you, Seekins and Christensen have sold a buttload of 6.5 PRC’s in the last couple of years. It’s safe to say, I have seen more shooters with short magnums in the last 5 years than I had in the decade before that.
