However, a top of the line modern bolt rifle these days will put 10 shots in 1" (good shooter, solid optics, and tailored load). I would say, yes, that is more accurate.
Yes, that is more accurate. But keep in mind that the targets I showed were fired with rifles using
sights, not scopes. And the first target shown that was fired with the K-31 was even fired with Swiss military surplus ammunition! All the loads fired from the 03A3 were cast bullet loads and again, sights...no scope. Can you imagine how these old warhouses would shoot if they had scopes on them?
I handloaded for, and shot top of the line modern bolt actions for 20+ years before I ever owned a milsurp.
Some will put 10 shots in 1" @100. I owned for years a Ruger 77V 220 Swift that would shoot teeny tiny groups, but probably not 10 shots groups unless I would have fired really slow and kept the barrel cool.
I have on numerous occasions fired 3-shot groups from my Whelen with a 225 gr. TSX that went
under 3/4", but I again, doubt seriously it'd do that for 10 shots unless I shot very, very slow.
I think the older (military) rifles were designed for sustained fire as oppossed to modern hunting rifles whose design attempts to balance accuracy and portability.
The question in the OP was "Are modern rifles as good or better than old". I think modern rifles
can be better than old, but in many cases are not. And by the way, as many good milsurps as I own and have owned, I own far more modern bolt rifles.
