SAMMI Announces Acceptance of Three New Cartridges

I'm no fortune teller, nor can I foresee the future, but I don't see anything in these three that will take the place of anything already available. In fact I'll go as far as to say all three of these will not be much more than a passing fancy.

It's got to be a thrill to come up with something like a new cartridge, and see it accepted by SAAMI. But the real test of it being accepted is when shooters accept it, and unfortunately I don't see that happening.

Neither of these new cartridges are liable to replace some other long standing and proven ones. There's just simply no need for them, nor a reason for them. There might be a small cult following for the .277 Fury, but the others will soon be lost to time and memory I'm afraid.

Then again I could be wrong! I've been wrong before. ;):):)
 
The .277 Fury is the civilian version of SIG Sauer's 6.8mm cartridge developed for the U.S. military's Next Generation Squad Weapons (NGSW) program; consisting of the Next Generation Squad Weapon-Rifle (NGSW-R) and the Next Generation Squad Weapon-Automatic Rifle (NGSW-AR).
 
22 to 35cal range - 25cal. The msr world and forgetting the bolt action all together. 55k to 65k on pressures. The future might be your 40watt plasma gun, but until that time I'll stick to this.
 
I've been a re-loader on and off for the better part of 50 years and always held a healthy regard for the pressures I was creating in some of my loads. Now obviously going back that 50 years leaves many newer cartridges out of the conversation and I've not gotten into many if any at all of the newer ones as far as reloading. And considering my most numerous loads were 38spl and 357mag, both of which I used for silhouette competitions around the southeast for a lot of years, with the .270Win my most used hunting rifle. In fact there were several years where the wife and I together shot several+ thousand rounds, all totaled in competitions. Now I did load for several other calibers, but not nearly in the quantities as I've mentioned here.

As I stated in my first sentence, I always had a real respect for pressures, and back then it was unusual to find a load data listing PSI numbers. Most everything published back then seemed to be in CUP's. Well, just a little while ago I went to the SAAMI site and took a look at the .277 Fury simply because the .277Win is my all time, all round favorite caliber ...... hands down, no BS about it. Well obviously there's not much common between the two, but I read the pressures at something around 85,000 psi, and was not measured in CUP. Folks that's one hell of a high pressure.

Simply put, I just don't foresee me ever being interested enough to bother with the .277 Fury because: #1 - It's just not a cartridge that enthuses me in any way, and #2 - That's the kind of pressure that if used in an even mediocre firearm, or accidentally over charged during a reload, can/very well may cause some real havoc.

Sorry, but I just don't see the need or value outside of military maybe, and possibly some long range competitions. While it does provide a flatter trajectory out at distances, and offers somewhat more energy at distances, it's usefulness will be very limited overall.

I don't know ........ maybe just me! (y):):):)

277fury a 27-08 case with improved angle, but 80k?

Yes & no, the base & rim are steel that locks into the rest of the brass case to allow for the higher pressures, and the dimensions look similar but its a new design. There's only so much that one can do that doesn't "look" like an existing design & still fit in a firearm.
 
I've seen the ss base for the increased pressure, but case length being the same. There are a lot of 308 based cases even though rim thickness. headspace and a few other minor differences.
