Ruger RSM "Stock Tip"

Guys,

I've stumbled across a supply of RSM stocks, for those of you looking for a spare. They're available at Numrich online, at gunpartscorp.com. They have 2 versions, and don't do a very good job of describing them on the site. I've ordered both and returned the one that didn't work for me. My RSM is a .458 Lott, but the two they have are for ".416 Rigby Heavy Barrel" and ".375 H&H/.416 Rigby Heavy Barrel". Here are the two part numbers and descriptions:

1153530 Stock, RH, Safari Magnum, .416 Rigby, Wlnt Cut-Checkered, Satin Finish
* This one is the "newer" version, for barrel band swivel stud forward of the forend.
1153540 Stock, RH, .375 H&H/.416 Rigby, Heavy Barrel, Wlnt Cut-Checkered, Satin Finish
* This one is for the older version where the swivel stud comes through the forend.

Search "Ruger" on left side of their homepage, then select M77 MkII Magnum. This will bring up a schematic, and the stocks are on the last page of it. Other parts can be found by looking at schematic. I don't think it's allowed to post links on AH.com so I'm trying to abide by that rule.

Both are $202.20, and require rear swivel, grip cap/medallion/screws, and crossbolt to be installed (available through Numrich as well). The one I got had nicer grain than my factory stock...by the way, these are Ruger-made factory stocks.

The one issue is that they appear to be made for a heavier barrel shank than my .458 Lott has. There's about a 2" long gap that will be filled in by bedding on mine. Not a huge issue to me, especially in view of the difficulty of finding these stocks!

I'm attaching pics comparing the two versions listed above (taken before I returned #1153540), as well as a pic of my Lott in the stock that shows the gap I'm talking about. The one on the left in the first 2 pics is #1153530, and on the right is 1153540. The wood is obviously nicer on the 30! These are pretty dang cheap; better get one!

Interesting. I have a .338 RSM with a nice stock, Circassian as I believe at least one of those is.
BTW, I just ordered a copy of your book. Thanks.

Thanks! I definitely think these will only fit the .375/.416/.458 Lott RSMs, and even then the barrel channel may need filling in a bit (no idea why they were machined this way, unless the .375 and .416 RSM barrels have a much bigger shank than my Lott?).

I believe they're all circassian walnut...though one of these is relatively plain.

Perhaps they were factory goofs and that's why Numbrich has them.

I think you're probably right. Hard to see how that could happen. I believe they have about 60 of the 1153530's.

Qty. 60? Holy crap!

Yeah, that's what they told me. Must've been a big overrun or something.

Thanks for the heads up. For some time I have been looking for an economical way to reconfigure/reduce the bulky dimensions of my Ruger RSM in .416 Rigby. It balances like carrying a 2" x 4". I will order one of these and whittle it down into something more hand friendly... Like the overall dimensions on my Winchester 70 in .375 H&H. I am hopeful that the replacement barrel shank dimensions are more commensurate with my 2nd generation RSM which has the barrel band above the stock fore tip where John Rigby originally placed it. The .416 Rigby barrel shank assuredly has some substantial girth to it. I had previously sent this rifle back to Ruger as the magazine box shifted effectively turning it into a single shot. Have not shot it since its return. They said to maintain certain torque settings... (it was within specs before sending back). Ruger does not want to see these rifles glass bedded. I wonder why? The cummulative affects of recoil would be mitigated by increasing the surface area. Any thoughts?

Sounds like these would be a good option for you in that case. Just make sure and order:

1153530 Stock, RH, Safari Magnum, .416 Rigby, Wlnt Cut-Checkered, Satin Finish
* This one is the "newer" version, for barrel band swivel stud forward of the forend.

Couple questions for you: Did Ruger actually tell you not to glass bed your RSM stock? Also, what torque settings do they recommend and for which of the screws?

Thanks

Nailed the 1153530... I was afraid they were going to be out. The torque setting is 95 inch/pounds for the front mounting screw which is accessible under the front part of the magazine hinge and the others forward of that. The specific screw setting for the rear mounting screws (DO4802 & DO4700) which are front and rear of the trigger housing are 20 inch/pounds. The threaded cross bolt going into the imbedded gear looking nut is supposed to be finger tight to avoid cracking the stock.

Regarding bedding.... Ruger Customer Service states that voids the warranty.

They did not charge me anything to correct my out of alignment magazine box ... but the action on my year 2000 RSM manufacture in .416 Rigby was not bedded.

Thanks again for the heads up on the stock. Previously when I got the notion to buy another original stock to "reduce" and called Ruger they asked either $1,000 or $1,100 for the replacement in Circassian walnut. Like that was ever gonna happen. The next alternative was a stock-maker and I was checking into that when I stumbled upon your post.

I better start thinking where am I gonna slim down that stock. The wooden V that comes up near the right thumb web & hand might as well be a butter knife. I seriously wonder what was the story on the making of the original RSM stock contours. They flattened the bottom of the stock like it was a bench rest rifle. I have a hand that requires a "large" glove so consider that, yet the circumference around that original stock is.... well let's just say impressive.

Here is the schematic... strange in calling Ruger today they don't even have the cross-bolt listed anywhere and Numrich's is OUT . Ruger Service Dept is closing shortly for summer holiday according to the young lady that assisted me with the torque specs. (I wanted to make sure I wasn't doling out bad torque spec info).

Thanks; good info! Hard to believe the 2 small screws out on the forend require 95 inch-pounds too? I agree about some of the RSM contours, although I'll likely leave mine as is. Good luck with your project!

I kept asking the young lady at Ruger regarding those bottom fore-end screws and she said 95 inch/pounds. It does seem high but isn't there a brass insert to prevent compression?

What's the story behind your original stock? If I had half a brain perhaps I should have asked if your old stock was available since I am going to be reworking the shape anyway.

How many working days did it take to receive the parcel from Numrich's ?

I believe it was 6 or 7 working days to get it from east to west coast. My original stock is good; I ordered the additional one as a spare. So I'll be hanging onto it, but thanks.

Got the 1153530 stock I ordered from Numrich's in short order (about 3 days) and sent it back the very same day. The stock was beautiful.... except there were a series of small knot holes right where the barrel lug fits into the stock on the forearm. Fearful that that would be a contact point that was prone to cracking I sent it back. I am awaiting the replacement, The Customer Service woman at Numrich's was very, very attentive and pleasant to communicate with. She said she had a quantity of 67 remaining and would get me a suitable one (that was knot free in the lug race-way) for my .416 Rigby reduction project.

That's a lot of RSM stocks! Too bad about the knot holes. Hopefully they'll get you taken care of.

Received a very nice stock today. Unfortunately it was for a Ruger Long Action. I realized it right away as I was taking it out of the box and noticed there was no foretip. Third time around is hopefully a charm!

Wow, sorry about that. They obviously shipped the wrong part #. That sucks!

How many of you have glass bedded your RSM rifles?
I got one last summer in 416 Rigby and worked up some loads to carry around the elk woods in Colorado to get used to the heft of the rifle.
Now I'm starting to prepare the rifle for a trip to Zimbabwe so I pulled it apart to glass bed it and then read this string. I will admit this is my first foray into heavy magnums ( anything above a .340) and just assumed I should glass bed the action - maybe not??

Also foreign to me is the recoil lug extender? I have never bedded a rifle that did not have the recoil lug as a machined protrusion on the bottom of the action. This rifle has a separate bar with the recoil lug cast / machined on it that then sits below the front of the action.

Your response and experience would be much appreciated.

If it shoots well and no other issues, best to leave it alone. I have a .338 and a .416 and both shoot very well so no real need to bed. Some smiths deride the plates and bars Ruger uses in the big boys but as long as it works...

Ozone, bedding the RSM will be a royal pain. If you feel the need to bed though, first, place a proper recoil lug beneath the barrel (doing away with Ruger's system). Second, be sure to epoxy a threaded rod through the grip.
