My father has a 30-06 Springfield, as well as, having an aggressive form of arthritis similar to rheumatism. Anyway, I found reduced load data for this cartridge on the Hodgdon web site in the youth section that uses a 125 gr. Ballistic Tip that will cut down on recoil by about 50%, which is a good thing. My question is, since the sectional density is only .188, is that still adequate for deer size game? I have read a couple of articles that state that you should have a bullet with the sectional density of at least .215. Granted, the 125 is only .027 off and shot placement still needs to be on the money; I was just wondering what other people were using successfully. I know that in my 06 with 150 gr. Ballistic SilverTip kills deer dead good enough, but other opinions are greatly appreciated.
