Quote: G'Day Fella's, The only down side that I can see is, the Rem 700 long action has a magazine box, long enough for a .375 H&H Mag cartridge. In the case the .375 and .416 Ruger's, they only require a mag box long enough for a .30-06 cartridge.
The flip side of this 'down side' is that monolithics are proliferating and are long for their weight. A 375Ruger in an H&H length action has space enough to seat the 400gr monolithics out to maintain maximum case capacity.
You could also consider a 375RUM, just need a RUM magazine box with cut-outs. Might as well run faster than the 375Ruger seeing as you can in that action. Cheers... Con
