to me, the biggest reason is twofold...
1. the nostalgia
2. the cool factor which is off the charts.
As SteveR says, it’s not the shoulder angle, which necessitated the H&H belt for headspacing.
But the long neck & shoulder from cordite days, which makes it so cool,
un-WSM or perhaps un-Rum even.
Usually it’s the long magnum action , with a classic stock, and stunning performance that is the art.
The whole is greater than the sum of the parts, which all work in concert.
I could be very happy with a cf arsenal that consisted of 6mm/244Rem, 280 Rem,
And a pair of 300 + 375 H&H CRF .All matched, of course.
No need for high pressure throat burners.
Just steady pointing , with clean slick feeding for follow ups.
Cheers
