I've used the Mark X actions for rifles for years. I've always been very pleased with the action and barrels. The new version being imported by Daly looks good as well.
The Mark X is a basic commercial 98. Trigger block safety. On the 375 version most if not all the box length increase is in the front. This removes metal behind the lower lug. I've never heard of a problem. The none 375 can be picked up for around $300. The 458 and 375 will run $425-500.

Reed, I agree with Ramrod on this rifle. Good value for the money and actions good enough to start a rifle project on. I have a 375 with a synthetic stock and it is a good accurate rifle. Also have a wood version in 25/06 again an accurate rifle and it looks pretty good. The only negitive I have abou the rifle is the side safety which lock the trigger and the bolt (unless they changed this). The safety works a bit stiffly and its hard to get a good thumb purchase on the safety.

BigBullet, The safety on the MKX is just about it's weakest feature. Of the two I have out of the stock both HAD the bolt lock. I remove it off of all of mine. Take a cut off wheel and remove the tab. It takes 5 seconds. That way you can cycle the bolt with the trigger still blocked. Key issue is to make sure you re-adjust the screw on the safety if you make other adjustments to the trigger.

The Mark X action are as said above by others a very good action to start your gun with . i have had a 35x378 jc and two 7x61 S&H and a 458 win mag and a 9.3x64 made on thoses action and have no troubles with them ever

I have a 375 and a 458 in Whitworth Express. They are both very fine rifles and frankly I like the thumb safety. I find it smooth and very easy to use but of course I also have a dozen older Rugers with the tang safety and all my shotguns except my double hammer have the tang as well. Buy Two and when swithcing back and forth it is like shooting the same rifle. I stole my 375 3 years ago but paid around $600 for the 458. I think that was near the price for a couple that sold a short while ago here on AR. I hear about a whitworth in 7mm but wonder if it isn't an urban legend as I have never seen one. Go for it and good luck Frank

This would seem to be a nice example but overpriced. I do like the aftermarket safety which would seem to preclude the concerns mentioned.
For whatever reason I haven't come across many of these in the St. Louis area...but then again I rarely find myself in retail gunshops any more. Nevertheless, I haven't seen one in my own hands yet. I'll have to keep my eyes open down in Tulsa perhaps.
Thanks for the advice.

I've got one getting tuned up for Africa by Hill Country Rifles as we speak. Found it on AR Classified and paid $600 including Talley mounts and rings. Great wood, fair to middling inletting. It needs a little work with feeding and ejection, which is why it's at the gunsmiths now. I also found a good deal on a Timney trigger and picked up a pme 2 position side safety from Brownells, so those parts are going on as well. I see them periodically at Gunsamerica or a local gunshows ranging from $550 to $850. I like mine a lot. Bob
FWIW, I have Whitworths in 7mm Mag. and .300 Win. Mag. Not too sure how rare they are, but they're out there in the identical configuration to the .375 and .458

Amazing. This is the first I've heard of one in 300. Do you believee it to be factory original or re-done after leaving Manchester? I think I may have to try for one. Thank you. Frank

Rest assured, the MK-X is a fine action to build a DGR on. I have done dozens. The action can benifit by polishing it inside the ways to smooth it up, and on a DGR I like to change the bolt shroud for a military one, and install a TWO position safety like the Chapman. I also change out the trigger for a military one, that I rework so it's only a single stage, with no creep and no backlash. It's fool proof and can't get out of adjustment, and it will allow Me to make the stock with the minimum amount of wood removed from the area behind the magazine. (Reall not an issue with a 375, but it really can help with the 416s and the big 45s)
The .300 is factory original. I have seen one other at a gun show. Some time ago, a dealer on one of the auction sites had original Whitworths for sale in .270 and .30-06. A friend of mine bought the .30-06 and has been very happy with it. I believe these were made in the later years, when the quality of fit and finish had started to drop.

I absolutely dote on mine. 1" groups with 300 gr. Nosler PT's at 2755 fps. The only change I'll make is the safety. I will replace it with one of Gentry's M70 style versions or switch out the shroud for a military one and to the Buhler type. Otherwise, she's mine 'til I die. And my wife is on orders to bury it with me!

I have two -- one in .375 and one that was converted to .416 Rem. Couldn't be happier with both of them. As far as quality control is concerned, I cannot speak of this with any authority as both of mine function very well, have good fit and finish and are very accurate. They are a bit on the light side. My .416 weighs 8 lbs 11 oz and kicks like hell on the bench.
