I have a new in the white FN mauser action dated 1953. I've had it for my guess close to 20 years. Never really paid much attention to it, just knew I had it and would use it someday for a project. I didnt realize it was 375 H&H length untill I looked at it closer at it last night. I realized I don't have bottom metal for it.

I have a new Sunnyhill 375 length piece of bottom metal, but was planning on using that for a 300 H&H barreled action I have.

Pretty sure Sunnyhill does not make bottom metal anymore or even sure they are in business anymore. I know that Blackburn may still make 375 length bottom metal but dang they are pricey.

I doubt I have many options as to who is making 375 H&H lenght bottom metal for Mausers these days, Blackburn may be my only option.

I'd like to get comments on what my options are, maybe someone is makeing bottom metal I am not aware of. I also plan to post in the classifieds, thats where I bought the Sunnyhill bottom metal I have, but that was at least 15 years back.

It sure seems to be hard to get Mauser stuff in this day and time, guess I'm getting old, but probably not the only one on here.

Comments please.

Thanks, Billy

You should put your order in now for a Blackburn, I have had one on order for months.

I believe sunny hill is selling only through brownells.


Just curious on that action...presume you mean the receiver has been lengthened to 3.6, has the load/ejection port also been opened?

Does GMA sell bottom metal only? Not sure if they do??

You MIGHT consider the 416 Rem bottom metal..Pretty simple to "squeeze" the front to make it compatible for the 300/375., They might have it in stock..just bought one last week, did the above and works perfect. BTW..the price is actually darn reasoballe

BaxterB,

Yes, looks to be opened on the bottom to 375 length. Its more rounded in the front where a Whitworth I have is more square in the front. On top it's been milled at the ring, just like the Whitworths I have.

Duane,

I want to make sure I am reading this right. Remington 416 mag bottom metal is same centers and can be modified to fit my FN action. I thought the holes were different measurement for some reason. Not sure why, but thats what I thought.

Thanks Billy

Billy,
he said he bought a BB in 416 rem, and they might still be in stock, i assume for a mauser

scroll down to the mausers, and there's a 416 for mauser

Does FN Supreme bottom metal hold .375 H&H?

Only if the box is made for the length of a 375.
The FN Mausers were just hogged out inside for the 375; otherwise like any standard length 98, and all bottom metal has the same screw spacing; they are not special receiver lengths. I have lengthened standard military boxes to fit the 375.
The FN does have very thin lower locking lug seats, which some don't like. It makes the receivers weak. Does that matter? You decide.
When I do a 375 on a 98, I remove metal from both front and rear, thereby leaving most of the lower lug recess intact.
A better option for a 98 is a 376 Steyr. Of which I am building two right now.

dcpd,

376 Steyr is a neat round. Built one 15-20 years ago, can’t remember Jeff may remember we blued it in his tank.

I have two other 375 H&H, but not on a Mauser. One is a Remington the other is CZ550. Figured 375 H&H would be good use for this action.
