If it's possible to do a .375 H&H on the Ruger MK 11 is it possible to do either the .416 Rem mag or .404 J........................standard M98's can be opend up to accect this round so is it possible ?? | ||

I think the Ruger actions for those two chamberings are the same. Getting the .404 to feed properly will probably require additional work. Does Ruger offer that rifle in the RUM chamberings? If so, that might facilitate the feeding somewhat. You may also want to ask this question on the Gunsmithing forum. George  | |||

 You may also want to check Jeffeosso threads re: the AR rounds. He built my 416 on a Ruger and is also looking for another for the .470AR. | |||

PC, yes, they can be modifed to take the longer rounds, with a good deal of work. I built the 416 AR and 470 AR s on rugers, the 416 on Frank's tang safety, and the 470AR on the ruger m77 mmkII. Either was easy as heck jeffe opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

http://www.riflemagazine.com/magazine/article.cfm?magid=84&tocid=1186 they make it look easy, though I suspect there was more to it than they describe. I'd like to hear about any real experiences doing this as well. | |||

Jeff, The article claims a new mag box is needed and the ejector and bolt stop need to be cut. Anything else involved? What would it cost to convert one? My biggest fear is when I die my wife will sell my guns for what I told her they cost. | |||

I would have thought that it would not be any more work to build say a .404 J on a MK11 Ruger than it would be to do it on a say a 1909 Mauser......................yes there would be a fair amount of work no doubt but it could be done I would think. | |||

Jeffo what are the cartridge dimensions of these rounds in compariosn to the .404 J and the .416 Rem Mag ?? | |||

Has anyone actually had this accomplished to a Ruger? My biggest fear is when I die my wife will sell my guns for what I told her they cost. | |||

I suppose I am figuring if an m98 action can work for these rounds then the Ruger Mk11 should to ?? | |||

What would be really slick would be a .404 Dakota (2.580" case with .404 Jeffery case head) on a stainless Ruger M77MKII. No action lengthening required. No nostalgic appeal either, but hey, it's a Ruger! I want one of those. | |||

Brass would be a pain in the ass for aussie shooters with that one RIP. | |||

You can buy the parts from Ruger for the conversion to a normal long mag. No big deal. I do the same when I take a new M70 from normal mag to long mag. Most wood stocks don't even need much inletting changes. As to the 404 etc. I have no idea. As usual just my $.02 Paul K | |||

As ramrod says, get a M77 375 HH box ($10 from brownells) and dummy it up, you will soon see what you are up against. | |||

While waiting for some headstamped brass ($1.40/piece USD) to arrive, just trim down some .404 Jeffery and fireform. Why weaken a standard length Ruger M77MKII by opening it up? Here we go again. | |||

| One of Us |
Ramrod, did you run into any difficulties doing the conversion? After you were finishe were you able to eject loaded rounds? My biggest fear is when I die my wife will sell my guns for what I told her they cost. | |||

You won't weaken it, you'll file back on the "trigger group housing" and work the bolt stop. i wouldn't do it, for 10 reasons or more.. the first being a 423 vs 416 bullet  jeffe opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

Left-hand stainless Ruger 77 MK II, originally in 7mm Remington Magnum, converted to handle 458 Lott (same length as 375 H&H). Work done by Bill Atkinson of Prescott, Arizona. Works fine.     Comparison of 458 Win Mag to 458 Lott. Hammer | |||

I really like my Ruger .375 H&H that Bill Atkinson re-barreled to 375. I have also seen another 458 Lott done up. It does not appear to be much work and does make a handy. light and fast bolt rifle. Anyone who claims the 30-06 is ineffective has either not tried one, or is unwittingly commenting on their own marksmanship Phil Shoemaker Alaska Master guide FAA Master pilot NRA Benefactor www.grizzlyskinsofalaska.com | |||

boom stick, I bought the .404 Dakota dies and brass on Nov. 29, 2004, on a personal visit to Dakota Arms in Sturgis, SD. You did not give me the idea. Why does this matter anyway.  Jeffe, That is good if most of the opening of the action can be done to the rear. Too much trouble for me though. I'll stick with what will fit in the standard Ruger M77MKII's lying fallow, such as the dreaded 7mm Remington Magnum.  I am just going for the cheap and easy .404 Dakota, and it is not at the top of the list in priority either, seeing as how I have been sitting on the brass and dies for over a year. Another reason why I did not jump on your AR band wagon. Congratulations on your feat.  | |||

Hammer and 458 Win, Could you tell me how to get in contact with Bill to have this done. Approximate costs? Do you consider the rifle DG worthy? This could be exactly what I am looking for. My biggest fear is when I die my wife will sell my guns for what I told her they cost. | |||

Hammer, Thanks for the pics, again. I will do a .404 Dakota like that, with NECG peep and banded front sight. My simple tastes and the lighter recoiling .404 Dakota will allow me to dispense with the quarter rib and not need any recoil lug on the barrel. My sling swivel stud will point forward on the forend tip. I don't care for barrel banded sling base either. African sheep Rifle No. 3 is in the works: 1. Winchester M70 .404 Jeffery 2. Dakota 76 African .427 Lapua Kifaru 3. Ruger M77MKII .404 Dakota. | |||

i was just wondering if what you had described was the same idea of or something different... but i figured it out it is something different... this forum is definitely for the "road less travelled" kinda people... the 404 jeffery is kinda growing on me. 577 BME 3"500 KILL ALL 358 GREMLIN 404-375 *we band of 45-70ers* (Founder) Single Shot Shooters Society S.S.S.S.

why not take the easy route, use a model 70 in any magnum calibre? I picked up a decent shape M70 in the ubiquitous 7mm Remington Magnum at our local gunshow last month, serial #G107,XXXX range. I have just finished fitting three, 300gr Silvertips into the magazine and bolting them up far enough to extract. That tells me that this is a simple barrel change to produce a 375H, 416Rem, or 458Lott. Add a synthetic stock if you will, and there is a 7.5-9.5lb rifle, depending on bbl contour and length.

Now why would anyone ever do something the easy way when a more difficult way can be found ? That would have me shooting prairie dogs with a 223 or 22/250 instead of going to all the effort to do it with a 219 Donaldson Wasp. | |||

Snowwolfe, I would think that any reputeable smith who can open up an m98 for the larger rounds would have no dramas opening up an MK11 I suppose action work would be around the same $$ | |||

A 7mmRemMag Ruger MKIIM77 box (target gray stainless with Tupperware stock) will hold 3 down of the .404 Dakota. It is too tight but it will feed and the bolt will close with 3 in the box. This is a case where all that is needed is an extra 0.1" of box depth, or better yet just windowed box and reshaping the follower a bit, top and bottom. The rails and ramp seem perfect as is. Those little .404 Dakota rounds sure are cute, and they do 2400 fps with a .423/400gr bullet. It looks like I need a single stack to put the .457 Lakota Boomstick into a Ruger, but we shall see about a new box for staggered feed before giving up on that. I am doing the .404 Dakota (10" twist McGowen stainless barrel 23" long)as research for the .457 LB. The .404 Dakota: The Other Boomstick | |||

Rip, you'll just need to window the mag, and the 458's will feed fine.. at least the 458 AR does from the same platform jeffe opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

I see that the .404 Dakota is a cinch in the Ruger from the 7mmRM action donor. Easy. I am sure your AR line is too. My .458 is the .457 Lakota Boomstick, on a short necked Lapua/Rigby head size. I will give it a try, but it won't be quite so easy. | |||
