This is my load for 300win mag , Winchester large rifle primer's , Nosler 165 ballistic tip , IMR 4350 70GR. work up to this load as 71 gr's was showing pressure signs in my rifle. Nosler ballistic tip may not be the bullet of choice for heavy boned game but this combo works great for whitetails. I have shot deer with it and they never took a step , just went straight down.
