RE: 280 vs 7mm-08
You didn't say, and no one has asked, what do you plan to hunt with these cartridges????
If it's deer or blk. bear, then they are pretty much equil. For something bigger, then you need heavier bullets, and for bigger game it's best to have those heavies bullets driven a bit faster, like a 280 Rem. will do!
I really like my custom light weight 7 Express Rem.. (.280 Rem.) I've put a lot of meat in the freezer with it!
