Re: 7 Ultra Mag vs. 7 STW ???
I have two 7mm-300 ultramags and five 7mm stw's. The 30 inch barrel ultramags shoot 200 fps faster than my 26" barrel stw's. Barrels were gone in under 500 rounds with the ultramag. Have not shot out a stw barrel yet. The 7mm ultramag was to much of a barrel burner for me. I did my 7mm-300 ultramags back in 98-99 time frame well before the 7mm ultramag was introduced but assume it is the same thing or very close. Don't know if any of this helps but I can get more notes on it for you if I dig a little. I just shoot from the hip on this forum from whatever I can remember. And the older I get the less I remember.
Predictions are difficult, especially when they involve the future
