I am in the process of building a 284 Winchester on a long action, as a 1000 yard and in all around hunting rifle. It will have a 24" McGowen Pac-Nor #5 contour bbl. that I am having Twisted Barrel do some crazy fluting to. My plan, as of right now, is to run 150gr LRAB, as it will mostly be used on deer, antelop, and thin skinned animals in general. I will load 175 or 180 if I take it elk hunting, which I doubt I ever will because I will have a bow in my hand most likely for that. I have a ton of H4350 that I shoot in my 6.5 Creedmoors, I am hoping it will work well in the 284 as well. Does anyone have experience with H4350 and 150 LRAB's in the 284? I guess any of the lighter bullets with H4350 would be a good comparison to hear about as well. I might run the Berger 140's if the LRAB don't shoot well in my gun, as I think I could push them pretty hard and still have a 1000 ft/lbs of energy out to about 800 yds or so. Any help would be appreciated.
