Just curious if anyone up here is running the Sherman Short Cartridges ?

I have a .338 Blank from benchmark I was planning on running a 338 RCM (which is basically a 6.5PRC Necked up to .338 so not totally worried about brass.)

But I am also curious about the 338 SS sounds like its quite the hammer to say the least.

rs=w:400,cg:true,m


Cheers,
B
 
The velocities Sherman claims seem unrealistic at standard pressures. You can get more velocity than a 338 win mag with 10gr less powder? There's no free lunch in ballistics...

Cool looking cartridges. But call me skeptical.

This!! Only by running insane pressures can that SS 338 equal or exceed 338 Win Mag velocities. Dave.
 
That is so obvious to anyone who has done much reloading.

Just as with any engine, there’s no replacement for displacement. Leaning on brass that hard will quickly display itself in expanded primer pockets and short case life.

They are a nice idea, but as others have pointed out, there's no free lunch.

Their velocity expectations are pretty unrealistic without being high into pressure, IMO.
 
I don't know if the Sherman Short is running higher pressures or not but I have read about +p chambers that supposedly allow increased powder charges (and velocity) without increased pressure.

Sounds like voodoo magic but maybe possibly might work?? :)

Yeah. Voodoo magic is a good descriptor. Lol
 
Any cartridge can be loaded hot and over pressure. I like that my 338 SS fits in a short action, I’m shooting 210 Barnes ttsx at 2835 out of a 22” barrel. Not maxed out and extremely accurate.
 
Cool to play with developing a new load, but were it me, I would need to have a goal in mind t justify doing so. One needs to ask: Can it be done, and should it be done?

6.5 CM is a good example of a great cartridge that does absolutely nothing any better than already existing cartridges. It this case, the sole reason for its creation was to make money for a couple companies; not to bring a better product to the hunter/target shooter.

SS does nothing better than anything else, and not as well as most.

As Dan stated above, "no free lunch".

The Creedmoor was in fact designed as specific match cartridge for short action "across the course " rifles, and it does that better than the 308, 243, or 260 for shooting and cycling the bullets that it was designed for.

Examples of cartridges that do everything 6.5CM does? I'm not aware of one.

As we are no longer restricted to AR style mags, the 6.5x55, 260 Rem, 6.5x57 etc. - dan

Those are substantially longer, and put you into a different size of action and magazine. The Creedmoor clearly offers a substantial difference on this alone. Then you add the fact that its SAAMI spec requires faster twist barrels to allow for factory ammo to use the most efficient bullet designs and we now have two critical differences that justify its existence.

That argument might hold weight if gun manufacturers followed SAAMI specs for twist rate, but it only takes like 5 seconds on google to show that you can get all sorts of twist rates for different guns in the same caliber - sometimes even different MODELS of the same rifle.

The creedmore was designed around ar mags, hence its length. Twist barrels are simple, i see the new Remington 243's come with 8 twist barrels. Magazine length in bolt action guns? They are all over thenplace. Pick the one that works for you. No, the biggest advantage of the creedmore has been marketing. - dan

And they feed better, so what. The CM, as I said earlier, is a good cartridge, but is totally redundant, unless you have shares in Hornady.
