Talley (and other) scope mounts for Winchester Model 70s are divided into a few categories. In Talley’s language, one is “magnum-length” (.300 and .375 H&H) and one is for “standard caliber” (.30-’06 family plus .264/.300/.338 Win Mag… no mention of .458).
The action on my .338 Win Mag seems to be long enough to accommodate the .300/.375 H&H cartridges… but there must be some kind of difference I can’t see.
What’s the deal, please?
