I am sure the 275's are a great bullet, but surely he can get his/your rifle to shoot something being made now....My .338 will shoot the 210 Noslers into .455 and the 250's into about 3/4" don't see the need for 225's or heavier than 250....kill anything on the North American continent..

Call Speer and see if there are any lying around somewhere, you never know..
