I had one of mine taken back to 22 inches as part of sporterizing it.
In the new Boyds stock, perceived recoil is handled much more efficiently & with a rubber buttpad.
Lighter weight, but recoil is not objectionable.
Sight radius in my case was not an issue, they were removed in favor of a scope. But you would have that issue if you re-mounted some sort of front sight.
And, when I chronographed three loads through it, no real loss in velocity over a longer barrel.
Can't explain it, just mentioning it.
I wouldn't bother to shorten a Mosin's barrel & leave any of the military wood on it, but in making one into a sporter with glass, there's no overriding reason to leave the barrel that long, in my opinion.
