Lets have a look at my bolt action sporting arms

.375 H&H Mag - "Whitworth" Mauser 98 action - FN or Mark X action

.30-06 Parker Hale 1200 - Santa Barbara (or FN) M98 action (?)

6.5x55 M96

a spare ex-mil action or two ...

an "unmentionable" Remington in .222.

A couple of SMLE's.

The top two didn't need any action "modification".
