Will any new Rifle or Pistol cartridge/caliber become common?

[Flechette]

It's not the gun that's the problem. It's the brass.

I do not think that the cartridge case is the weak link if it is fully supported by the breech. For example, look at the M1 Abrams tank. The extremely high muzzle velocity M256A1 120 mm uses cartridge cased ammunition instead of breech loaded bullets followed by powder bags like battleships in days gone by.

I thought most of the rounds were combustible cases?

6.5 Grendel is growing very quickly.

I don't think that the entire case is completely consumed. I think that part of the cartridge base still needs to be removed after each shot.

In any case, there are solutions to the problems that high chamber pressures create. I think that a gun that fully supports the case, especially around the base, could be designed to tackle the high pressures.

Steel can be used instead of brass and the cartridge internal dimensions designed to handle higher pressures.

I certainly do not have all the answers how but I am sure that there are solutions.

I think it'll require a big innovative step in the firearm platform to shake things up on the cartridge/caliber side.

If you are smart enough to call this one you are on the wrong forum. You need to be betting on horse races. The American shooter is less predictable than a jumping frog.
What about the ancient .45-70 Govt. it is a true "Revenant". The 45-70 was dead for over 100 years. It returned in the 1970s. Who could have predicted that?

> Personally I won't own a caliber that isn't sold at Wal Mart. Just my 2 cents.

When you reload, parts is parts.

True, I'm shopping for my first 45-70 now. Can't decide if I want a repro of an 1800's lever gun or a modern lever gun, likely a Marlin in that case. Or do I want another form factor

You have your common (standard) calibers such as .45, 9mm, .22lr, .30-06, .308, .338 and so forth for rifle and pistols.

However, there are new calibers being made all the time and even older ones are gaining newfound popularity, especially in the AR15 platform such as .300 Blackout, .300 Whisper, .204 Ruger and others. You're seeing new rifle calibers such as the .26 Nosler, .28 Nosler, and now . 30 Nosler.

I can't think of any newer pistol calibers but the old .380 has quickly become more popular due to so many people with carry permits including women.



I know the general rule when I was younger and buying a rifle was buy a rifle that can handle anything you ever think you'd hunt (for me it was elk on down), in a caliber that can be purchased anywhere because if you do hunt out of state and you need to pick up ammo you'd most likely have a limited selection at small local stores and would want a common caliber that most people carried such as .308, .30-06, and .338. It would be a bad idea to purchase a rifle in a caliber like .300 Blackout because if you lose your ammo and need to stop at Woodland Sports and Gas in the middle of nowhere they are most likely going carry those common rounds and not the .300 Blackout. I know at most small stores you could find 9mm and .45, although .380 could be hard to find in many stores still despite it's popularity.



With the advent of new calibers occurring all the time do you see any rifle or pistol caliber/cartridge becoming a common one or have all the common ones already been basically set in stone.

Historically, the pistol caliber has driven the commonality. Other than the common ones, 22lr, 9mm, .40 auto and .45 auto, there has not been much else done.

Rifle-based calibers, other than .22lr, would usually require a single shot gun in pistol caliber, which is not attractive for SD.

Now we are going to talk history. The handgun was born as a Cavalry a weapon. A Pistol was a Spanish Gold coin so named by the French. The 105 grs. coin was likely 1/2" in diameter. The handguns of the 16th Century had bores of this size. Hence the Pistol.
The next step was to add a stock. the first carbine. In 1847 the Colt Walker was designed to fire a carbine load and replace the carbine. This could give you a headache.

Single-shot pistols are the simplest possible form of pistols and are known to have existed in AD 1365.[6] The earliest handguns were single-shot, muzzle-loading guns with ignition provided by inserting a smoldering match cord into a touch hole. As such, they were essentially nothing more than miniature cannon, small enough to be handheld

Those Chinese cavalrymen must have been tough, to be able to ride a horse while holding a minature cannon in one hand and sticking the match to the touch hole with the other hand.
