RE: 30-06sprg 125gr.
Quilly,
I've been using the 125 gr in my 30-06 for years and have not had a problem. Both Winchester and Federal load the 125s'. I used them until I started handloading and now I load my own 125s'.
I've killed deer out to 284 yds (longest shot I have from one of my stands), and as close as 10 yds, also have shot loads of hogs with it. I went to Co. this past yr for mule deer and loaded 165s', was assuming I would need the heavier bullet for them, however, I believe I could have taken the mulie with a 125.
My personal opinion, for what it's worth, no, I don't think they are to light for whitetail.
