Won't feed or eject reliably. Are the guns total garbage? What and how much work to get them to function for DG hunt?

Thanks again

As with any factory rifle, some will work great, some won't without a little tweaking.

Impossible to say how much or what without knowing what it is doing.

Yep they are. I think you should give it to me to be safe. I have MKX actions on the majority of what I shoot. I've never had one that if it didn't feed correctly couldn't be made to do so with a little effort. I would have no issue useing the MKX as a DR provided it was tweeked.


As usual just my $.02

Ditto, are you using factory ammo or relaods?

And was it a factory 458 or a rebarreled smaller magnum? BIG difference if the action wasn't tweaked for the 458. I believe the factory 458 uses the same opened-up action as the 375 which gives the blunt 458 more time to come up out of the rails and align with the feed ramp and chamber mouth. May have a slighly different ejector blade too but I'm not positive.


"Experience" is the only class you take where the exam comes before the lesson.

My mkX Whitworth .458 runs great. It shouldn't take much to get yours running.

My Whitworth 458, from the factory, feeds great:
No, the receiver is not cut out at the ramp as in the 375's, less COL with the 458 Win.

Is your rifle an original Whitworth from Manchester or a Mark X that has had a 458 barrel installed? Beeg Difference!!

Mine has the same 458 electric pencil marking on the bottom of the action as pictured above.

I had to open the underside of the rails at tad to keep rounds from sometimes popping up but after thirty years of hard use it is now the most reliable rifle I own.



Anyone who claims the 30-06 is ineffective has either not tried one, or is unwittingly commenting on their own marksmanship

Ever time I see that picture of Phil's .458 posed on the bear skull I want to caption it; "I'm just here to kill somethin' Can we get on with it?"
Yep. That is a gun worth loving.

I've never heard of any that were original every failing in any regard.
Additional information on your part would make it easier to help.

I once owned a Mark X .458 that had been rebarreled from a smaller caliber. I had to weld up and extend the ejector about .100" to get it to eject 100%. It fed just fine. I suspect a little feed rail work will make yours feed reliably as well. Don't give up just yet,I own and have owned a number of Mark X's, all were very good rifles.

P.S. Phil's .458 has been an inspiration to me for years, what a great rifle!!
