Remind me who the people were who opposed the transition from muzzle loader to bolt action. I seem to have missed out on that phase in history.
The opposite of what you are talking about is "change for the sake of change". It seems to me that there is a good deal of that nowadays. For one thing there is the proliferation of cartridges which represent little or no improvement over their predecessors.
In the 1950's, when I started getting an interest in hand loading, there were comparatively few factory cartridges and virtually no big game cartridges available. The interest in wildcat cartridges went wild. Now the situation has reversed itself and there are practically no wildcats which have not been tamed into factory cartridges or have been replaced by factory equivalents.
I can remember when the long range target shooting sport was dominated by the wildcat .30/.338 cartridge, used even by the military teams. Nowadays all the nooks and crannies of special purpose demands have been filled with factory cartridges.
As a military team shooter, I used the service rifle, a semi-automatic. As a civilian team shooter, I used a bolt gun. If I had felt handicapped with a bolt gun, I could have used the service rifle, but I never did.
