RE: 7mmstw v. 7mm ultrmag
When I had my 7MMSTW I loaded the 140 grain Partition to about 3100 fps. It took down every animal I shot with one shot. When I used the big casings it was so I didn't have to crowd the limits. I loaded my 30 calibers with 180 grain bullets. What would have been a hot load for my 30-06 was a mild load in my 300 Win Mag. I had trouble at close range with the older Ballistic tips in my 7MM Rem Mags. They were fragil at close range. I understand thet Nosler beefed them up a bit since then. I use them a lot in the 308 and 30-06. Also in the 280.
