When I purchased my Weatherby Mark V Ultra-Light rifle, used, I wanted to start right off testing the 130 Grn. Nosler Ballistic Tips, for my 270 Win. I had seen how they work on deer while on a hunting trip years earlier. The Ballistic Tips worked very well with both H 4831SC and also IMR 4350 powder. In my rifle which has a 24-inch barrel. 4831SC produced so many ragged one-hole groups, so that combo of powder and bullet became my number 1 choice for whitetail deer hunting. I also use the same 130 grn Ballistic Tips, with IMR 4350 for my friends Model 70 featherweight, also a 270 Win, with a 22-inch barrel. His rifle likes that powder with that 130 grn bullet. The approximate velocity from my rifle is 3000/3025 fps . The bullet is accurate in my rife and devastating on Whitetail Deer!! Several one-shot kills. I don't know how it could be any better!!! That rifle is my "go-to " deer rifle . No further bullet testing required for that rifle, or my friends Model 70 . Sometimes you get lucky. For Target and Comp guns, the testing never ends.
