    Have a chance to buy a rifle that is stamped 35 mag on the barrel , even the seller doesnt know exactly what caliber it is .
    I managed to find one reference to a 35 magnum on an RCBS caliber list that I found online but not a single other reference anywhere , I'm thinking that its probably a 350 remington mag or maybe a 35 ackley magnum either of which I can find or make ammo for , I'm no stranger to loading for wildcats .
    Has anybody heard of or had experience with this vague caliber description before , any information would be much appreciated .:confused:

    Ackley, Whelen, Remington, H&H, Rigby, practically everyone had a 35 Magnum of some sort. Until you do a chamber cast and compare it to measuements of cartridges, you are not going to know what you have.

    Dies for some of the "exotics" can be expensive.

    Thats my plan if I get the rifle , also by the bolt face , action length , whether it is belted or not these are all factors which will narrow it down , was just hoping someone had seen the basic marking "35 mag" before.

    Yes I have seen those markings before on a 35 G&H (Griffin and Howe) magnum rifle, the gun was made in the earlier part of the 1900's and was stamped on the left side of the barrel "35 Magnum". The rifle that I mentioned is owned by my FIL and it also has 24" barrel with folding sights. If indeed the rifle you are looking at is a 35 G&H magnum, it is one rare firearm.

    Yes the caliber is 35 G&H, we make the brass from full size 300 H&H mag cases and have the dies to neck up to .358 caliber. BTW, FIL rifle is built on a magnum mauser action with a french stock.

    Still ?????

    Well I got the rifle today , looking at the chamber it doesnt appear to have a magnum belt but does seem to be a rimmed case , threw a 35 whelan case in to see the fit and it rattles around like a .223 in a 30-06 chamber so whatever it is its huge !! I have ordered a pack of cerrosafe so that I can do an accurate chamber casting and take measurements , this is gonna be fun :D

    just doing some rough sizing the rim measures about the same as a .303 british at .053-.054 overall case length is about 2.70-2.71 base to shoulder is approx 2.25-2.30 diameter at base approx .50 bore diameter at muzzle is .35 .

    Obviously I will get much better measurements once I have a casting , but until then if anyone has a book on old cartridges that they could find something close it would be really appreciated .
    Its about the size of a 350 no2 rigby , but if it is that why is it stamped 35 mag. ?

    The dimensions you give are very similar to the 350 Rimless magnum (Rigby), dimensions for the 350 Rigby is:

    Bullet Dia: .357
    Neck Dia: .380
    Shoulder Dia: .443
    Base Dia: .519
    Rim Dia: .525
    Case Length 2.74"

    The above was taken from COTW 3rd edition.

    The old .35 Newton case does not have a belt. The three rifles i've seen in this caliber were made by Newton.

    After the cast

    OK so i did a chamber cast ....

    What I have is as follows ;

    neck .391 dia by .422 length
    shoulder .498 dia
    base .514 dia
    mag belt .535 dia
    main body length 2.16 from bottom of shoulder to top of belt
    case overall length 2.85 approx from case mouth to guessed base, rimmed part sits outside of chamber so was not cast

    The closest I can find to these dimensions is the .358 STA (shooting times alaskan)

    Only problems that I have with that is that this is an old gun and the STA was developed in 1992 plus why was it not marked that caliber ? so anyone have any more ideas ?
    Im pretty sure its not the G&H the shoulders too broad and its too long to be a norma or remington magnum did weatherby make a .35 magnum ? case dimensions are the same except the neck for the .375 weatherby mag... if anyones got a spare case or loaded cartridge from an STA that they are willing to part with for me to check against it would be appreciated I would of course return it after the measuring process if needed , I know these big cartridges are not cheap or easy to come by .
    all in all im still not 100% sure .

    Looks longer than the .350 Remington Magnum if the case right below it is a 7mm Remington Magnum. Maybe a .35-.338 Winchester Magnum?

    Please be sure you know what the cartridge is before you start loading ammo :).

    Just my .02,

    By his measurements if he measured pretty close looks darn near right to me.

    His measurements--------------------- .350 Rem. Mag.
    Neck .391----------------------------- .388 + or - .003
    Shoulder .498------------------------- .495 + or - .003
    Base .514----------------------------- .513 + or - .001
    Belt/Rim .535-------------------------- .532 + or - .003
    Case Length 2.85---------------------- 2.80
    Case Length he Guessed, so looks darn close to me........But I don`t know if I would go out & spend 60 buck on a box just to see if it fits.

    case length on a .350 rem mag is 2.17 , overall cartridge length including the bullet is 2.80..... just the case on this is as long as the entire loaded cartridge on a rem mag , I did a little more than guess the rim protrusion I measured the length of the 7mm rem mag rim from the belt and added that to my case length , bolt face is the same as a 7mm rem mag .

    after doing some more research I have found that the A square company makes 358 STA on enfield 1917 conversions , this one doesnt look like any of their current offerings but it could be an early one or a customer special its completely glass bedded like theirs and the case looks identical , ill contact them and see if they ever marked their barrels in this way .
