The 7mm-08 is the American alternative to the 7mm Mauser or the 7x57. A little shorter but a bit higher operating pressure (46,000 versus 52,000 CUP). With that comparison established it is worth noting that Rigby and Company thought the 7x57 a good enough round to call it the Rigby .275 and according to the A Square manual it was used as an "elephant thumper", not only for brain shots but for body shots as well. Realistically, I don't think anyone would recommend that today. It was also used extensively for lions, buffalo and leopard. That's not me talking, that's Finn Aagaard talking. I am not knocking the .300 but I am bragging on the 7mm. It will do all you want it to do in the lower 48 with a lot less powder and superior accuracy. Short action, light rifle, mild recoil, plenty of velocity, limitless supply of brass and bullets...what's not to like?
