Thread: A bit of 7mm advice

To get the real advantage out of the 180ish grains you need bigger than a 7mm mag. The 160gr projectiles are the sweet spot for the 7mm mag capacity calibres. What is the issue with seating to mag length? Do you not have the accuracy or velocity you are after?
The WSM/SAUM case diameter cartridges are not ideal in a T3 due to action/barrel diameter. I remember Greg Duley writing something about it. Something about barrel thread diameter being too small and getting too much expansion.
