Re: Who owns a 300 wsm ar10T?

I know the Armalite required a special magazine due to much wider body contour of the short action ultra mag case.
Maybe you gain 100-150 fps over the standard .308 with a saum cartridge? Is it worth the extra effort and cost? Wasn't to me.
Thought about going with a 10T upper in .338 Federal recently. Would like the extra bullet weight, but same diminishing returns influenced me not to buy. </div></div>
The problem with .338 Federal as a LR round is that it just isn't enough case for the high BC .338" bullets, worse than .308 Winchester and the heavy .308" bullets IMO.
