M98 in 7x57 suited for heavier bullets ?

[PAUL_MAUSER]

I have read on here that the Rigby Highland Stalkers aren’t throated or suited to shooting the heavier 175 grain bullets and are intended for the 140’s. Does anyone know if that’s the same truth for the plain M98 rifles in 7x57?

I would assume the barreled actions are exactly the same as what’s shipped to Rigby but didn’t know if there is a chance that Rigby spec’d theirs that way and the regular Mausers aren’t.

Have used 156grn....170 grn and 175grn in mine without any issues....actually never even thought about it

My Highland Stalker shoots 170's sub MOA.

That’s good to know. Im on a mobile device now so harder for me to search for where I had seen that on here. Seemed Rigby was warning someone here that a heavy longer bullet would hang up in the lands or throat and upon extracting a live cartridge could pull the bullet from the case. Several in that thread said they had sent theirs off to JJ to have them chamber reamed. Having to modify a $20k rifle right out of the gate to feed a common bullet weight turned me off a little reading that

That is a fair point, mine came from the factory with a longer throat. However, rate of twist is not an issue.

The Mauser brothers designed the 7x57mm cartridge specifically to take the 175 gr. bullet

A lot of the older rigby 275s were bought for derstalking in Scotland and England so were sighted for the 140 grn bullet which was the standard for stalking back then....I shot one here years ago i was looking at using 140 grn bullets Paul had given me to bring out..it shot high...and when i told Paul he said that one must have been made/sighted for the 175grn bullets....as Joe said RIgby will lengthen the throat when you order one.....but on my m98 as said no probs...feeds them perfectly

Did they do the longer throat on special request?

Historically as spike.t alluded, they had two models, one for the 140gr and one for the 175gr. (this is in the vintage era at Rigby). In the modern era you can get them any way you'd like. Regardless of what a gun is advertised, every gun is unique and the best way to determine it is to use an OAL test cartridge with your preferred bullet to see what seating depth your particular gun will permit with a particular bullet.

Many of the vintage Rigbys have just enough throat erosion and wear that they shoot 175gr beautifully even though they were originally for the 140gr.

You can always have the throat lengthened if necessary.

I have one and a .30-06. Both shoot every bullet I have up to 220's.
The .275 Rigby likes everything.
I am selling the .30-06 for $10k if anyone is interested. I have 10 boxes of ammo for it too.

Yes.

The modification is called “Deep Throat”.

My M98 shoots 175 grain lead-core bullets well. It truly doesn't seem to have a bullet weight preference. I should note, however, that I have not yet tried a 175gr monometal bullet, which might be a bit longer.

 

[daxter11]

7x57 is an awesome all around hunting round.But I have not thought of this .

 

[RichieG]

The throat design of a 275 is (marginally) different from a 7x57 and this is true in 275 Rigby HS. That said I would try the bullet out to see if it fits. The sleeker ogive of a 175gr Eldx fits perfectly in mine and shoots tiny groups at 2500fps. I guess the trick is to be aware that a longer bullet could get jammed in the lands and increase pressure so be aware of it. Good luck.

Yes but there is always some idiot thinking they are smarter the the genius that invented the non- parallel worlds best bolt action
