VAhuntr-I actually own two 7mm stw's,a 7mm ultra and two 300ultras.I only see about 50 to 75fps advantage with the 7mm ultra over the 7mmstw's and I use the stw's for all my deer,pronghorn and sheep hunting because both are a little moe accurate than my 7mm ultra.I use the 7mm ultra for long range shooting practise and the 300 ultras for hunting elk and moose.
