Re: What I found out about my 270WSM
Depends on what your goal(s) are. One philosophy is to pick a bullet and find the right load, willing to change brass, primers, and powder, with the latter 2 being most common.
Another is to choose a rifle, then find the right bullet, which takes longer, usually. You obviously have a satisfactory load with a 150 bullet.
If you wish to continue with the 130 SST, there's a good chance you just need to change powders.
It is reasonable to consider the following powders:
VV N160, N165
IMR 4350, H4350, XMR 4350
IMR 4831, H4831SC
