.270W vs .280Rem with Barnes X

Why?

In Barnes Reloading Manual .270W reach higher velocity with 140 and 150grs bullets than .280Rem!
My experiance tell my it should be the other way.

Are Barnes loaddata for .280Rem mild to fit some auto-loaders or what?

I have just begin to load Barens bullet in my .280 (have done it in .270 with succes!).

That can't be the reason, there are far more 270s autos than 280 autos. I think they spend less time developing loads for the 280 because the 270 is more popular.

.280 Sweden,

Welcome to the forum.

I think this might be due to the different rifles they used.

Some rifles are faster than others - even in the same caliber and make.

In general, the "official" (e.g. SAAMI) .280 Rem pressure is lower than the equivalent for .270 Win. Reason: the .280 Rem was originally designed to work in autoloaders.

The fact that one can safely load a .280 Rem to the same pressures as a .270 Win (in a bolt action, say), is another matter.

When that is said, whatever velocity figures are published in loading manuals, and whatever velocity figures you'll actually observe in your particular rifle are two different kettles of fish. Take those velocity figures with a grain of salt. They are nothing else but statements about what velocities sombody has achieved, no guarantees about what you'll achieve.

.280SWEDEN,
Another thing you might want to look at is the model rifle and barrel length used to develope the manual loads. With the 140 and 150 grain bullets the difference between these two cartridges is, in my opinion, more imaginary than factual. Of the two cartridges, I think the .280 is the better cartridge. But only if heavier bullets such as the 160 grain bullet is used, say for elk. Good luck. [Big Grin]
