I know the .308 has many offspring, any most guys like them all, and have heard some say we need a .270 verion of the .308, does anyone think we do? Some say because of the .270 Win. we don't need a .270-308, anyone have some points to make why we do need a .270 version of the .308? Also can we call it the .277 Win?

We don' need anymore spin off calibers, especially right now, we've seen 15 or 20 new calibers in the last few years..

They should've called the .270win the .277win in the first place.

No. Its .007" away from a 7mm-08... and you can only shoot up to 150gr bullets out of it. The .260 will shoot flatter and faster, and the 7mm-08 has a greater range of bullet weights for the reloader. The .270-08 would bring absolutely no marketable advantage to the table.

Why in the world would we need a 270/308 when we already have the excellent 7mm08 that would outperform it handily in the first place? It takes a lot of thought and a gap to make a cartridge a go along with(especially)good marketing. I'm still is process of developing my new wildcat cartridge I designed but it is the ONLY 7mm cartridge that duplicates ultramag velocities in a STANDARD length action. I necked down the .375 ruger to .284 and so far looks VERY promising.

I would rather see a 25-08.

And so is the .270 and 280.I don't see the point here.

Personally I would like to see a .270-08. IMO it would make an even better whitetail cartridge than the 7mm-08.

It's called a .270 because that is the bore diameter of the barrels before the rifling is cut. The groove diameter (groove togroove)is .277 inches as is the bullet diameter.

Same with any 300 mag, 30-06, 280 Remington, .330 Dakotaetc... etc...

I'm aware of the how and why, I was attempting a joke, didn't really come out right. Hard to show voice inflection with typing.
I honestly could care less, if they invent a 1000 more cartridges, They are in business to make money not to stay with the standard. But, there's no point to it.

Ok, gotcha.

There are a bunch of people that ask stuff like that on here a lotand you being fairly new here I didn't know how much you knew.

Me too..

Me three.
