Well I'm about ready to "attack" the Whitworth and get her ready for shooting.
She needs some serious bedding work along with a few other refinements.
The magazine box needs some work as does the standing rear sight and the safety button.
The trigger release is crisp and nice weight but the face of the trigger is horrible and has a rough feel.
The bolts cocking ramps need a bit of a tidy and the bolt could use a bit of slicking in the receiver and will get lapped.
I've already sorted the feed which was not perfect when I first got the rifle.
She now feeds the 500 softs real nice but I still have to check it with solids.
Feed ramp will get a polish.
I would love to shorten the barrel by 1 1/2 inches to make it a 22 incher and may do this later.
May also alter the ballance slightly and add a little weight as this rifle is pretty light for a 458.
I'm looking forward to having a play with this rifle both in the workshop and later in the scrub.

There appears to be three totally different large cal rifles based on the Interarms barreled action.
At the lower price level is the Mark X Alaskan, next is the Whitworth Express and at the top is the Churchill One of One Thousand.
The Whitworth Express seems to have had several variations and the Alaskan and the Churchill might have done also.
