7X57 Mauser

[La Dano]

Is anyone casting for 7X57? I've got a sporter 95 action I'm thinking about casting for. Also about to pickup a 98 in the same cal.

[303Guy]

Unfortunately, no. But the 7x57 has to be about the sexiest cartridge there is. Even sexier than the Brit. I've thought of chambering a Lee Enfield in 7x57 and I bet it would work. So would a 9.3x57 .... Now that would make a great cast boolit shooter!

I cast 0.285 RCBS in 145 and 168 gr. and a Lee 130 gr
use them with 18-21gr of 4227 equivalent alloy is 50:50 coww : pure lead

[Larry Gibson]

I cast for my "sporterized" M95 7x57. You will, no doubt, find the milsurp barrels to be "oversize" at .286 - .289 +/-. That's not really oversize as it was the European standard groove diameter for the 7mm. British and US is .284. I have the 287448, 285377 and the original Loverin style RCBS 28-168-FN moulds. I mostly use the 28-168-FN as it drops at .287 - .288 and is the best fit in my M95. It also fits perfectly from the GC at the base of the neck to the lead driving band just kissing the leade, basically a perfect fit in the throat. The short stuppy 287448 is very good for small game and plinking loads. I have a .288 H die I lube them in.

Suggest a longer 150 gr or heavier Loverin design that drops at .288 minimum with #2 alloy (best to slug your barrels though). If the bores are good that bullet should shoot quite good even if initially a thou or so undersize.

The "oversize" barrels are why most do not shoot cast in them.

I to cast the RCBS 7MM-168 along with Lyman 287346 and 287442.
The only one I shoot with any regularity is the RCBS in a 1909 Brazilian, the mold has to be
beagled to get as cast dia. .290 then sized at .289 for the 1909 to shoot good.

[Bret4207]

Been shooting my 95 for years. Been some time since I last played with it but IIRC I was using the RCBS 28-168FN and 2400. I think 14.0 grs. Nothing special in the accuracy dept really, but I wouldn't stand downrange from me if you took my cookies. Mine I'm STILL working on getting the jacket fouling out of. I've been working on it for 15 years at least! Every time I think I've about got it I'll see some lead grab in a new place. Personally, I love my 95 and the 7x57. I think Americas hunters would be a lot better off with 7x57s than the various magnums that encourage ridiculous Hail Mary shots and world class flinching.

No truer words spoken!

Don't know about the groove dias of other 7mm 95s, but mine is .286 in original Chilean M95. Really good luck with the 160 gr Lyman 287641 of fairly soft alloy over 18-20 gr 5744 as per Lyman data. Sized just enough to seat gas check- final sized diameter is about .285-6.

I might add that my Chilean M95 is nearly unfired and definitely unissued. That may account for success with the bore riding 287641. With bullet seated to normal depth, when chambered, the lands do lightly engrave the nose.

I cast for my Chilean DWM M1895 7x57 using Loverin 150 gr and a Lyman 135 gr. The Loverin gives the best accuracy

[screwcutter]

I've been shooting the 287641, just seat gas check, pan lubed with Lyman's start charge of 5744. They come out about .286, I have a 1908 with a tight groove of .287 that I am messing with.

[koehn,jim]

By all means you should cast for it. Most European 7mm are around .286 and need a larger than American dia.284, there was a group buy on here a few months back for a 150 grain .288 mold that works great in my 1908 Brazilian.You need to slug your bore and go by that to pick a boolit.

.
I'll second the Lyman 287641. Loaded under IMR-4895 or like burning powder is a real winner in a 7x57 case. It's a bore rider design, so push the COAL as far as your magazine and throat will allow. For j-bullets, I like a 150-154 grain under a minimum dose of IMR-4320. Check your manuals for the particulars. If you have a 1:8.66" mil-barrel twist, you might consider a 175 grain boolits/bullets. It's a great cartridge to cast, reload and shoot.

Enjoy,

I have a modern Remington 700 in 7x57, it is amazingly accurate and puts venison in the freezer. The 303 British is another game getter that has been around for a while.
I just picked up an all matching 1945 BSA No5Mk1 today, I blasted a few rounds off today just make sure it works.
I also got an RFI bayonet with it as well, $350 Canadian, I think I did well.
If 303guy would be gracious again and post pics, I will send the pics along to him once they are uploaded onto my computer.

I've had the same idea. I have checked the fit and feed characteristics of the 7X57 in a No.4 action, it works just fine and ejects smartly.
I suspect it would work just as well in an SMLE, though a 2A action might be a better starting point.

[fa38]

I use the NOE 150 Hunter FN bullet. Casts at .276 nose and .2865 bands. Sized to .285.

21.5 grains Benchmark in the 1895 Chileno.
18.9 grs SPP210 ( 4198 clone) 1909 Argentine.

Both bores are like new.
The Chileno load shoots a bit bigger groups from the 1909.
SPP210 and Varget both work okay in the Chileno but the Benchmark load was best.

[KCSO]

I had a 91 Mauser with a commercial (Douglas?) barrel fitted in 7mm Mauser and it was a honey. The 7MM was plenty for deer and the gun shot with about any load. I made up a M95 manlicher sporter for a friend and he's been shooting cast in it with no problems for over 20 years, but he does have to cast bullets from a mould I laped out for him to 287.

I got it about 90% done from a guy who got it at the Puyallup gunshow. No idea who did the original work but it wasn't done bad. The barreled action was in "new" condition. I finished putting it together and put the Redfield receiver sight on it, converted it to cock on open, forged the bolt handle and put the hooded ramp front sight on it. It is a sweet little hunting rifle.

That looks almost exactly like a 6.5 Swedish Mauser a friend sportered back in the 80's. He went whole hog on the sights and mounted lever actuated quick detachable scope mounts and a British No.32 sniper scope.
The finished rifle was insanely accurate and quick handling.

Yes of course.

Looks at lot like my 6.5x257Roberts Arisaka, only mine is much darker and has a pistol grip. That particular rifle is very light, lighter than my 94 Winchester. An absolute joy to carry. I just haven't had time to do much load development.

Gotta love the Mannlicher style!
