Opening throat of long action for the long magnum cartridges

[Three44s]

Thanks Sharpshooter,

I am referring to the magazine port, more specifically the forward section where a longer cartridge such as the 375 H&H or 300 RUM would need added clearance for their bullet noses to clear.

I realize that the word "throat" is not appropriate where it's used almost exclusively to name the forward area of the chamber.

So my question is whether I can open that area up on a Savage 110 to accomodate the 300 RUM or 375 H&H and then switch back to standard magnums or even standard full length .473" based cases later?

OR am I going to have to dedicate any long actions that are modified that way to only those extra long cartridges and only single feed the standard cartridges in them?

Best regards
