What's the next greatest rifle chambering?

There are two problems with the 7X57 and all of this period's designs for the modern cartridge developer.

The first, and absolutely fundamental problem, is that they don't fit modern 'short' actions and magazines like the AI and MDT designs. Any rifle manufacturer producing a modern long action will only do so for much larger and higher performance magnum class chamberings. (Actually, the 7X57 and others are neither short nor long, but in-betweeners. When UK company BSA designed its own actions and rifles after WW2, it initially made them in three action lengths, including a 'medium' which was used for the 7X57. The importance of that cartridge in some markets in the 1950s was such that the first build of medium action BSA 'Hunter' models were 7mm Mausers not 308 Win, and they were produced before the company launched its long action version in 30-06 and 270 Win. The 'short action' was built around the 222 Rem and was also used for 22 Hornet, and later 223 Rem.)

Secondly, the cartridges were all saddled with modest maximum pressures when more recent post-war designs were moving up to the 60,000 psi mark, or even higher. Even though redesigned cartridges based on these cases could legitimately be higher pressure (as in 6mm Rem and the Roberts), manufacturers were likely discouraged by the fear of being smeared with the 'ancient, low-pressure' reputation.

This is exactly why I love my Tikka in 7x57.

No issues with action size and no issues with loading at modern day pressures.

Very fun cartridge and easy to tune. Brass has gone over 12 reloads so far.

There is rarely anything completely new in cartridge development these days.

I would say there there is not much left undone.

I was shooting a 6.5-08 AI in the 90's for High Power Rifle Silhouette before Remington commercialized the non-AI version so David Tubb could use it for the Hunter Rifle classification of the game.

Hornady is very good at taking something that has only a minor difference and promoting it.

I always surprised how easy it is to promote something as new with exaggerated claims for a minor difference. These are the times we live in now. Promition and profit is how I see it.

Do you think there was enough of an advantage to electronic priming for someone to try to improve on it and bring it back? What about a new style of priming?

With the hobby of wildcatting, i would go to gun shows and look
for quantities of brass, not in the mainstream. Some of them early
cases could be just catastrophic. I sectioned a 6.5 Carcano that looked
promising for a varmint cartridge. It was puzzling to see that it was
a balloon head case which design was used in pistol cases of years
gone by. They went to the scrap yard. Years later, I discovered that
this case was used as a black powder Hollywood prop. From that
time forward, any weird lot I purchased, went under the knife first.

Japanese cases, and mainly the 7.7's, I started to hoard. Hard to
find was the 6.5 Jap......Funny enough about these though, the
Japanese actually had the first version of the Creedmoor, and that's
no lie......LOL

So does anyone make, a true 6.5 short range BR bullet ?? VLD bullets
need not apply, and must be under 115gr in weight. i have a design,
I need to look at since my 7mm bullets are now depleted, and no more
will be made. It's quite possible there are none, or someone would have
a 6.5BR......

Let's see what trouble I can get into today......

Yes, a lovely cartridge. I've had four over the years, three historic arms Mauser service rifles and one 1950s BSA Hunter deer rifle. All good shooters - in fact the three Mausers (two by DWM; one by Steyr) were ridiculously good considering their age and the crude iron sights.

Maybe not the next but my favorite story about a new cartridge by FAR is told by Richard Schatz. When he first came to Deep Creek with a 6mm Dasher when the big stuff was still king. I just love that story.

The cartridge that I read the most about lately is the 7/6.5 PRC or the variation with your name of it, the 7PRCW. There is even a thread on this forum about loads being pressure tested. What are your thoughts about it making the jump into the hunting world? In particular, how it compares to the 280AI, another well regarded 7mm? Thanks.

.30 1000c4 doesn't use powder, C4 instead over 100,000 FPS

In all directions, lol

 

[kojaone]

A shortened .284 win case is the answer

shortened 284 necked to .25 cal

It would be ballistically very close to the 280 ai. Its already being used by some for hunting. While it is popular in F Class, you cant even compare it to the popularity of something like the 6.5 prc.

An electro magnetic rifle that shoots a tungsten bullet 7mm by 6 inches in length with a BC of 15.0 at about 6000FPS. that runs on a 9 volt battery that last a year.

It will be called the Tesla Gun.

Government can't confiscate it, it will be protected under the "Green New Deal".

For a while I thought that there might be a new family of cartridges based on the 300 RCM or the slightly smaller 338 RCM cases. The 6.5 PRC, based on the 338 RCM case may well be the only one, it seems. I eventually realized that much of the "magnum" performance of RCM cartridges was due to Hornady's superformance powders. I now suspect that the performance of the RCM family would probably be too close to the 30-06 family to be seen as a significant upgrade.

What about a 30 Super Accurate Rifle Cartridge Adapted for Serious Matches, or a 30 SARCASM for short? I’m thinking it is a 30-6.5PRC (300 RCM? Never heard of it ) with 30-06 performance in a short action but for real this time, unlike the 308 that needed a 20ksi advantage to “match the ballistics” of a Garand.

I believe that @tom did some work with this cartridge and named it the 30 Prick. I bet curmudgeons who don’t appreciate the genius marketing for the 30 SARCASM will still refer to it and it’s users by the wildcat name. I say it’s hard not to have a Napoleon’s Complex when you’re so short but have so much to prove with a big brother like the 300 PRC towering over you in the lineup!

I just remembered this from years ago on Benchrest.com.

The discussion centered around the pressure limitations on old cartridges. To be exact, could you load a 7x 57 to the same pressures in a modern rifle as a 308 Winchester. Many posted said that these cartridges were antiquated, they could never be fired at todays pressures. Even in modern firearms.

A shooter, now deceased, took a Federal 7x57 case and a Federal 308 case and split them lengthways. Laying them side by side, aside from the added length of the 7x57, the inside, from the case wall at the base to the thickness of the base, they were identical . .

Federal probably started with the exact same material, and up until the forming process reached the final trim to length and forming, the cases were identical.

This is why you can take a modern 7x57 case, (based on a case invented in 1892), neck it down to 6mm, Ackley Improve it, making it a 6mm Ackley, and shoot it at 58,000+psi.

You are right in one way!!! If it was made by Federal, it was modernized or made to accommodate the new higher pressure loads. The cases that could not handle modern day smokeless powders were imported and could have had the BERDAN PRIMERS AND PRIMER POCKETS!!! But, the really old military cartridges which used the old smokeless powder were designed for lower chamber pressures are long gone!!! The really corrosive mercury primers used in those days dissolved the brass and surplus was demilled with the brass being recycled!!!

Antique military cartridges from that age were demilled and were reassembled with dummy primers and no powder charge. The chances of reloading one of these cases is very, very slim and a reloader that would load one of those antique cartidge needs his head examined to see if there is even a brain in it!!! When SAAMI started, those old military brass were redesigned for higher modern day pressures!!!

BILL!!!!!

Pics coming, since most of my work has been based on the
shortening of the rebated cases. It will be all about the bullets
though and availability.....Coming to a theater near you.....LOL
