Hopefully someone can give you direct answer. I have never used them on whitetails, but did work up a load for roe deer in 2006. Of course these are much smaller deer, but the load worked very well on three roebucks. With 47gr of H4350 in Lapua brass, I got about 2950fps and really fine accuracy. This was in a Winchester Model 70 Classic Featherweight. I recently bought some 120gr Ballistic Tips with the thought that I might try them on southern whitetails.
