I need some opinions on a firearm related topic

I’ve recently discovered that there is a class of cartridges that are something between the full power rifle cartridges of battle rifles and the intermediate cartridges of assault rifles, and I don’t know what to make of them. The cartridges include 6.5 Grendel, .50 Beowulf, 7.62 Czech, .280 British, and .276 Pedersen. What would you classify these cartridges and the weapons chambering them as?
and if it’s something other than a battle rifle or assault rifle, please tell me what it is in the comments.

  • 6.5 Grendel is an intermediate cartridge, so a select fire rifle that fires it would be an assault rifle.
  • 6.5 Grendel is a full power rifle cartridge, so a select fire rifle that fires it would be a battle rifle.
  • 6.5 Grendel is neither a full power cartridge nor an intermediate cartridge, so a select fire rifle that fires it should be classified as something other than an assault or battle rifle.

Thank you if you took the time to answer all these polls.

Alright, the answer to this is actually quite simple:
The 6.5 Grendel was designed for the AR-15 platform, therefore it is an intermediate cartridge.
The .50 Beowulf is also used in the AR-15, and its case dimensions are closer to that of an intermediate.
The 7.62 Czech is similar to the 7.62x39, which is also an intermediate cartridge.
The .280 was designed for use in a select-fire bullpup assault rifle.
And the .276 Pedersen was an experimental cartridge designed for the Springfield 1903 and the Garand, comparable to the 6.5 Arisaka and 6.5 Carcano, which where both small, but still full-sized rifle rounds.

There are .50 BMG uppers for AR-15s too…
6.5 Grendel is noted for being a halfway between 5.56 NATO and 7.62 NATO, not just is size, but also power, and has better range than either.

.50 Beowulf has twice the caliber and muzzle energy of .223 Remington though

It’s also similar to 7.62×54 or 7.62×51

An “assault rifle” that emphasized power in semi-auto over controlability in full auto far more than modern intermediate cartridges do.

Not saying that these classifications couldn’t work, just explaining why it’s a difficult decision for me.

How is 7.62 Czech similar to the R and the NATO?

5

I can’t find a plethora of accurate statistics on different 7.62×45 mm, but it has muzzle energy and velocity that are roughly halfway between those of some 7.62×39 and 7.62×51 loads.

I am very confused by the idea that .276 Pedersen would be a full power rifle cartridge and .280 British would be a intermediate cartridge. They both send 140 grain .284" diameter bullets flying at ~2.500 feet per second. Are they different because the squatter case of .280 British lets it fit in a shorter action?

Don’t mind my vote, I hardly know anything about bullets.

Just 101.2

Don’t worry about it, you don’t need to be some sort of gun guru to voice an opinion, it doesn’t matter that much, since you can always just recast your vote. Just keep learning, and one day, you too can get into inane arguments about guns that none of us will ever be able to own with random strangers on the internet.
