Brno 21s and 7x61, are both equally not that common/unique and also of the same era(late 1940s')
after all, A new modern classic B/handle & Talleys aint exactly authentic Euro, so I though 7x61 would be more classic-offbeat interesting,than 7x64.

At the moment, I have four Brno 21/22 rifles and three ZG-47s and have had a few more. I much prefer to keep them in the cartridge "family" that they were originally chambered in and would prefer a 7x64 Brenneke to the 7x61S&H.

The case shape of the S&H may very well give feeding problems in that snug mag. well and tightly sculpted feed rails of the 21/22 action and since you lose a round in capacity, I see little point in spending the money to alleviate this problem.

I re-chamber the 22H rifles in 7x57 to .280Rem. and have two so modded, but, these were not pristine when I bought them. I have an action plus Kreiger bbl. and it will become another .280 with an Edge stock in the Sako Classic pattern....ideal chambering for this action, IMO. Mine shoot far better than I can now hold and are ideal "mountain rifles".

If, you wanted something different, find a ZG-47 action and build a 9.3x64B on it as my buddy had Ralf Martini do on one he talked me out of. This makes just an outstanding rifle and I love his...I just bought another very sanitary ZG and he is trying to get it to build an 8x68....NOT going to happen!

A pair, with the 21 action in 7x64 and the ZG in 9.3x64 are THE rifles to have, when using these superb Brno actions, IMO.

Is the 21 not a 'small ring' action?

I have never seen or heard of one chambered in a belted magnum but I am no expert, so may be totally wrong!

An old family freind of ours did almost all his hunting with a 7x61 S&H in a Shultz and Larsen rifle.

Dewey,
280rem is first on my list, 7x61 has some appeal though.
My need of a 9,3brenneke I feel is past, but always felt it was the perfect match for LR-98s'.
338-06 appeals more if I was to considering something above 7mm.

Kayaker,
the Little Hagns have a 7/8"[.875"] thread and are good for .473 caseheads,
I dont think theres drama with .980" threads and .532" caseheads, in fact the case is about .513 forward of the belt.
The GMA Kurz actions have 1.00" threads and accept WSM rounds (.555" casehead)

I agree with Dewey, 7x64, eight days a week!

I'd avoid the Sharpe and Hart simply because if you really want a 7mm Magnum you'd be better with a 7mm Remington Magnum.

However I also agree that the better option is either 7x64 or 280 Remington. The magazine was realy designed for .473" base diameter cartridges and, as other say, you may have feeding problems.

In the standard longer and relatively tight bored BRNO barrels you'll pretty much get S & H velocities with modern slower powders. As much as whatever you hit won't know to tell the difference!

My current project is a 280 Remington too...

I think it is pretty cool!

Many moons ago I thought the 7X61 S&H was the perfect rifle for North American big game excluding big bears. roger

Me too, Roger, but I got over it, and have two 280s now instead. I think the 7x64 would be fun. KB

Thye 7x64 is one of those often overlooked perfect and totally "cool" cartridges.

Hard to beat it with a 150 grain Partition.

One of my 1909s is going that way.

No difference between that and the .280.

9.3x64 can't be beat for most anything, any where. Mine is just about done.

I am also getting parts together for a 6.5x68/8x68 switch barrel rig for spanking whatever, out there a ways.

Anyway, bag the 7x61 S&H. The only 7 Mag worth beans is the 7mm Weatherby "downloaded" to 60,000 psi.

Oh brother...there is! In your pocket! Here in UK it is bad enough. Hate to think what ii is like in USA.

280 cartridge cases UK £31.00 per 100 = US $50.00 per 100. 7x64 cases UK £75.00 per 100 = US $120.00 per 100 are at least HALF the price of 7x64 cases! Similar DIFFERENCE on the USA Midway website too when I checked.

I bought all my 280 dies (RCBS)...AND a Lee Factory Crimp...on eBay.com for a few dollars. Again try and find secondhand 7x64 dies on eBay.

And you know what? 280 is a far better MODERN design that 7x64 with a greater capacity AND probably easier to find as loaded cartridges in the USA.

And lastly? I'd sooner have my rifle marked "280" any day than "7x64" which is just too...well...German! I prefer to keep my "bundook" in an "English speaking" calibre!

The .280 and the 7x64 were developed about the same time and one is NOT more "modern" than the other. There is NO discernible ballistic FIELD difference between them and the .270Win. is another that is equal, NOT, superior.

The comment about ...German!..., is a bit odd, as I might point out that the best Limey bolt rifles WERE German Mausers.......

Simply have to disagree with this last comment, as Dewey has said in his ensuing post, there is not a scrap of practical difference in them as witnessed by many manuals that state that starting loads for the 280 may be used to work up loads for the 7x64. It might well be different in other shires but here in NZ, I can buy S&B 7x64 for much the same price as any of the US made 280 Rem loads. 7x64 works just fine for me, built on a nice slim VZ33 action.
Steve.

The 7x64 was developed during WWI, and has become the "30-06" of just about every country except the US. The .280 didn't come out until the late 1950's, although some folks had been wildcatting a 7mm-06 in surplus rifles before that.

Anyone who thinks the 7x64 isn't cheap and available should just do a search on GunBroker.

The 7x64 is a slightly trimmer cartridge and tops off with a few less grains of powder than a .280, but I don't think most game animals have access to reloading manuals.

The Brno 21/22 have proprietary magazines that are very slim. They are designed for the slender shouldered 7x64 and 8x60. When you get up to a 9.3x62, you loose 1 round in capacity. The 7x61 may cause you to loose 2 rounds, and you will most certainly face feeding issues. You might also need a longer barrel to get full potential out of the cartridge.

Yes, way cool.

Ditto,

As a young guy back in the 1950's, I had a passion for the 7x61 Sharpe and Hart. I went with a 7mm Ackley Mag however.
Today, with the BRNO 21, I think I would lean towards a 7x64. A gunsmith can talk to the benefits and disadvantages of going either route, but I see the 7x64 as a better path to follow; again with an original unmodified Model 21.

Please note that I posted that the 7x64 and the .280 were DEVELOPED about the same time and this is correct, as the .280 is merely the ".284-06" and was being chambered in some commercial rifles around WWI...maybe Dubiel??? That is my point, not when the .280 was INTRODUCED by "Big Green".

KurtC is VERY knowledgable concerning classic rifles and seems to own many, ( that should be in my humble collection ) and he reinforces my original point concerning the 21/22 action's magazine...I just think that this would not be a very satisfactory or cost effective conversion and these actions are VERY hard to find, even here in Canada, where more of them probably exist than anywhere, except maybe Sweden.

This tends to make me very conservative with respect to any mods to these wonderful actions or original rifles.

The most powerful conversion I have personally seen was a full stock 23.5" model that was rebarreled to .358 Norma Mag by Continental Arms in NY, circa 1960.

The stock was cracked behind the tang.

Several have been done to 9.3x62, but that is relatively low pressure round. The factory chamberings were: 6.5x57, 7x57, 7x64, 8x57 and 8x60. I have heard of them in 6.5x55 and 8x64, but can not speak from experience as whether or not they were original.
