I have two customs
120g tripple shocks with R#22, fed 215, 3750fps
120g Tsx, IMR 7828, win mag, primer, 3850 fps
tiny groups with both
Brother has two also, we shoot the 140g Nosler C/T bullet at 3550 fps. Between the two of us, we have killed 100 deer at least, and we have never had one take a step after being hit, not even one step.
I use Vias muzzle breaks and brother does not.
My first 7 STW was in 1989 or 1990, right after Lane Simpson put out loading data. We fire formed cases with R#22 with the nosler 120g Solid base lead tips killing deer as we went, using 8 Rem Mag brass necked down.
The 7 STW will probably go the way of the 257 Roberts.
The 7 Super Mashburn is close which is fire formed out of 300 Win Mag brass and will give you more room in the magazine box.
I had my 7 STW reamer ground with zero freebore with a 1 1/2* leade angle.
