I'm ignorant about other than standard North American calibers. Can you fill me in on where the 7x57R fits, its downfalls and what it is good for?

It is the ballistic twin of the 7x57 but it has a rimmed case. Case capacity is a grain or two less and there are just enough differences between the two case dimensions that a 7x57 will not chamber in a 7x57R. It is used in double rifles and drillings where a rimmed case makes the mechanism of extraction simpler.

I have one in a combo gun. Kills white tails just fine.

Just like a 7x57 but I do load mine a bit on the light side. No use over doing a break open.

IMO right next to the rimless 7x57 as a great overall, medium-sized game cartridge.

I'll chime in with Gerard & pd shooter since they're right on the money with the 7x57R.

Many of the European standard "rimless" cartridges had a rimmed counterpart (or an "R" designation) developed for combination rifle/shotguns, Double Rifles, Drillings and Single Shots. 6.5x57R's, 7x57R's 8x57R's are good examples.

Why? Simply because tradition and personal preference favored the loading/extraction of a cartridge with a rim over a rimless version. Many of the cartridges were ingeniously arranged as almost twins but as Gerard pointed out so that the rimless cartridges could not be chambered in a rimmed version like the 7x64 vs. 7x65R. In some instances the cartridge will fit the chamber but supposedly has too much headspace to fire correctly.

Today there are manufacturers who make very good extraction systems for rimless cartridges but (like myself) many favor tradition and the alleged easier extraction/loading handing of rimmed cartridges in break opens.

I've loaded my two 7x57R's with everything from 120 gr. Barnes TSX's to RWS TIG 177 grainers. It's a great mild-mannered, accurate, low recoiling cartridge thats big on game taking capability.

Just below the 12ga barrel in my CZ. Excellant performance and easy to load for. Case life is good and I feel it's adequate for any plains game in Africa although I have only used the 7x57 on game up to Kudu. Loaded by most of the European companies but I have been using Selleir & Bellot with good success. My CZ shoots 175gr Noslers into about an inch.

"where does the 7x57R fit into the scheme of things?"

Into these little beauties!

Downfall? dont know if 7x57R has one.
Plenty people do have one though,mostly those who cannot afford such rifles.
I would allow my girl to have an affair if she bought me one of those little HagnSxS', that only fair,
cause she would not be seeing much of me for a while once I had that in my hands.

Whoever commissions one of these, Im sure they wont mind the annointed priviledge of having to order 7x57R brass.



Or one of these:

So, is the 7x57R in a class with the .270?

The 7x65R is closer to the 270 shooting 150 gr bullets, and resembles the 280 performance with all bullet weights.

Well funny thing is SBT,

An old hornadybook has 7x57 154gn@2900,162@2800 (22"bl) 3"oal
The latest Winchester superduper Supreme270 has 150Gn@2950(24")
ConleyCart.who load their stuff pretty hot,have
270-150@2900
7x57-150@2830,154@2780
280-150@2980,154@2960

Be fair, put 7x57R in a good strong falling block,give it a 24" like 270 nornally has,And any business one has pointing 270win at, can point 7x57 at with same confidence.
Some of the best down range ballistics youll get with 7x57-162sst.
But load up with 140-160tsx,154interbond,160accubond and I dont see you standing in 270win'shadow much at all.
Youd also be surprised what you can do at 300yds with 175gnNP@2500mv.

This has been very enlightening, thanks everyone!

According to the reloading sources I rely upon, which are not some posting on the internet, the loads for the 7x57R are supposed to be about 10% less @max compared to the 7x57 rimless. That takes some whiz out of the 7mm rimmed mauser, but it's still a great cartridge.

It's just that to get 7x57 rimless (shot in a bolt action) performance out of a break-open action, the 7x65R does that.

Anyway, that's why I used the 7x65R for comparison to the 270.

The 7x57 is a great round and it falls just short of the 7mm08 performance ballistically.

Actually, assuming that both will be fired in equally strong actions (e.g. the Remington 700 or the Ruger 77) the 7x57 can be loaded to somewhat higher velocities than the 7mm08, although commercial loadings for it, at least in the US, are a bit anemic.

It's the same situation as the difference between the 6mm Remington and the .243 Winchester. The 6mm Remington is the 7x57 case necked down to 6mm, while the .243 is the .308 Winchester case necked down to 6mm -- the 7mm08 is that same .308 case necked down to 7mm.

The 57mm case is a bit longer and slightly larger in internal capacity than the .308 Winchester case.

Well I don´t quite find that to be true, in the 7x57R one should only load long/sleek and heavy bullets like the 175 grains Hornady or other similar bullet.

with the intended max range of 180 meters they will deliver extraordinary killing power to all large game, here in sweden I an entitled to hunt all games with that load, even brown bear should I choose to.

This is in all a somewhat theoretical debate, try a good german drilling in 16/70+7x57R for an all open fall season of hunting and then you´ll love the little round as much as I do..

Best regards Chris
