Ive used several 270 cal rifles on deer hunts and from the results Ive seen i doubt you could do much to improve the results on deer at any reasonable range, its always performed flawlessly in my hand loaded rifles with 150 grain speer bullets over a stiff load of 4831
Ive got a ruger #1 that is amazingly accurate in that caliber, off a bench rest under 3/4" groups are common at 100 yards
