I have one of those rifles (FN Mauser Supreme) chambered in 300 H&H mag. This is the same action as the FN/Browning High Power rifles.

I am looking for a replacement stock. I have been looking at Boyds and B&C, but neither of those lists a stock for that rifle. Boyds lists a stock for the FN Mauser 400 and Prophet River lists a B&C a stock for the Mauser/Interarms Mark X.

Does anyone know for a fact whether any of those will fit my rifle with no or minimal modifications? Alternatively, what would be a source for a good quality, rigid and weather resistant stock for my rifle.
 
I am wondering if the H&H used the exact same action?? The cartridge is about 1/4" longer than 30/06, etc. Might be helpful to check what the centre to centre distance on your main action screws are - seems to vary with different lengths of mauser actions that were made. Take a look at your bottom metal - some designs have a "long tongue" - the metal goes 1/2" forward of the front actions screw - on others, the metal is perhaps only 1/8" ahead - apparently base on original patterns - some version had a locking screw behind the main screw, some had that little screw in front - resulted in two lengths of "tongue" even though the action screw spacing was the same. Then there will be the myriad of barrel shapes and contours to get the correct one, and the inletting inside for the magazine might be different than "normal" on yours. A good reason to have your old original stock handy - several measurements might be needed to get a correct replacement...

I guess I can think of several reasons why you will need some "luck" to find a correct "drop-in" for a FN Supreme in 300 H&H. Getting some good numbers off of what you have will increase your chances.

Very good advice. 98's are all the same, but all different as well, in one way or another. - dan

To address the points raised in your post:

1. the bottom metal reaches about 1/8 of an inch in front of the edge of the front action screw.
2. The distance between the two action screws (center to center) is about 7.9 inches
3. There is no locking screw next to the front action screw.
4. The magazine (huinged floor plate) accepts a cartridge loaded at "magnum length" i.e. 3.6 inches.
 
Sounds like you have it figured. Your Point #3 - most sporters do not have the locking screws, but the metal seems to have been made as if they were used - I would describe what you said as a "short tongue" - there are also "long tongue" variations - the replacement stock will be inlet for one or the other - you will want a stock inlet for short tongue. As for your point #4, the stock will not care about your hinged floor plate, but it will care about the box that is inside there - between your receiver and your bottom metal - usually one piece on a mauser - trigger guard, bottom metal and magazine box is all one piece, with floor plate, follower and follower spring attached in various ways. Some Parker Hale 98's have a separate box, but perhaps only for the versions that use a detachable magazine? Your replacement stock has to be able to accept your magazine box. I do not think a standard 98 mauser stock (with a 3.3" or 3.4" inside dimension magazine box) would accept yours??

When I said above that the stock will not care about the hinged floor plate, I was mistaken - I have now seen two where the stock was not inletted for the hinge for that floor plate - so there needs to be a slot or a recess up front, to allow the hinge on the floor plate to open - stuff will break if that slot is not there and you try to open the floor plate.

Long tongue versus short tongue - thought a picture might clarify. Left one is military with locking screw behind the action screw, next is a commercial made on that pattern. On right is a military with the locking screw ahead of the action screw and beside it is another commercial that was made to that pattern. The two commercial tongues are not the same dimensions.

Nice to have that stock as well. Those are very nice rifles.

I had one like yours but foolishly sold it, but was able to recently replace it with a very nice Remington 721 BDL in 300H&H. Not near as nice as an FN but it's a 1948 vintage and almost all original as it's missing the original pad but not cut.

My rifle is like the second one from the left: commercial, short tongue!
 
There is another thread on CGN where OP has got a replacement stock that he is going to have issues with - see 4th picture in Post #28. Not only is inlet too long for his bottom metal tongue, the shoulder for the magazine box are too large. Some maker thought this was okay for a "mauser" stock, and somewhere there might be a bottom metal that fits better, but this is what can result when mixing and matching and not watching for the details. https://www.canadiangunnutz.com/for...ema-of-CoreyTheCowboy?p=17514298#post17514298
 
I had a browning Safari (fn supreme action), that I had put in a Boyd’s. The 3 step profile of the browning barrel didn’t quite match Boyd’s offerings, as well as the front of the mag was short on my rifle and required a filler.

If I were to do it over again, I would go with a wildcat, it seems like they have the right profile and fit for a true fn supreme commercial action, as well a great reviews.

Try a Remington 798 stock that doesn't have a safety cutout or if you dont mind a small fill job?
 
I think the Zastava M70 is the Mark X, and the Mark X is a licensed clone of the FN98, which was a civilian clone of DWM 98. Husqvarna and Yugo M48 not so.

Could be wrong there are a lot of variants. Most aftermarket stocks are full of gaps and nonsense. The best factory stocks I have seen for inletting Mauser factory, FN, Parker Hale.
