RE: .270-308 Do we need one?
 

Actually it's .014. Which is twice the difference as there would be between a .277 and a .284. There is only .007 seperating a .25 Souper(.25-08) and a .260 Rem though... And yes, the .25-08 wouldn't provide much benefit there either, except more bullet selection than the .260 Rem.The 6.5mm's deserve to be more popular than they are. If someone would make a stiff loadwith that 130 gr. Swift Scirocco in the .260Remington, they'd have about the ultimate deer round in my opinion.

RE: .270-308 Do we need one?
 

Why don't we all just shoot .22lr, .223, 30-06, .338 win mag, .375 H&H and the .416 Rigby. No manufacturer would need to ever offer us anything else, everyone could hunt anything on the planet,and we would never ever need to question why the world needs "X" cartridge when we already have "Z, Y, Q, A, G, R"cartridges. [&:]Every one go throw away every rifle that youown that isn't chambered in one of these six cartridges right now.



We need it because there are people that want it and this is America dang it.

RE: .270-308 Do we need one?
 

No, we probably need a grand total of 30 calibers. I think we will see ammo and gun makers culling the herd over the next few years. I mean, c'mon, we're hurting ourselves. If we had only 30 ammo choices, ammo would be much cheaper. All this fancy choice has caused a box of '06 hunting ammo to go from $7 to $20 in 15 years. . . .and it doesn't kill any better.

RE: .270-308 Do we need one?
 

We don't really need one, but if you wait long enough, someone will begin making one. Outdoor and gun magazines will tout it as the best thing since a pocket on a shirt. Hunting shows will have guys toting it around. People will but it, gun manufacturers will be happy. Order in the universe will be maintained...:)

RE: .270-308 Do we need one?
 

No, we do not need it. But it is becauseof the 7mm/'08 that it is not needed. In fact, to be blunt, the .280/7X64mm makes the .270 Win. unneeded also!

RE: .270-308 Do we need one?
 

I have one in a wild cat ruger m77 that shoots better than any rifle I ever owned. It shoots a 140 grain bullet into the same hole at a 100 yards. I call it a 27-08 and a 257 Roberts is a 25-08

RE: .270-308 Do we need one?
 

Well, I say the .280 Rem isn't needed because we already had the .270 Winchester.

Although your argument about already having the 7mm-08 is a good one.

If you all got the .280 when we already had the .270 then I can have the 270-08 when we already have the 7mm-08. So there!!!!!!

RE: .270-308 Do we need one?
 

Do we need a .270-308? No.
Would a .270-308 sell some more rifles and ammo? Yes.
Would I buy one? No.

RE: .270-308 Do we need one?
 

No it ain't ... a 257 Roberts is much more like a 257 X 57mm since it's darn near a necked down 7X 57 case. It's much closer to that than a .308 case.

RE: .270-308 Do we need one?
 

No, the .257 Roberts is NOT a .25/'08. It is a .257/7X57mm. Just as the 6mm Rem. is a 6mm/7X57mm.... The .257 Roberts holds more powder than the .25/'08-(".25 Souper").

As for .264" and .284" bullets being ballistically superior to .277" bullets - theballistic properties of any caliber bullet depend on two factors-their sectional density (weight IN POUNDS divided by the square of the diameter in inches)and their form factor, or shape. (Sectional density / form factor = ballistic coefficient-B.C.) So if you take bullets of any given caliber, givethem a specific sectional density and identical form factors,they will ALL be ballistically IDENTICALregardless of their diameter - .264", .277", .284, .308", whatever. Of course, to remain ballistically identical, the shape has to remain the same, and weight must increase as diameter increases to maintain identical SD's.............
