I've actually never checked the twist myself, but from looking on their website every 270WSM has a 1:10" twist. According to Berger it's fast enough to stabilize their heavy 150gr VLD's, so the 130's shouldn't be a problem at all. I was also shooting their classic hunters, so they shouldn't have been as sensitive to seating depth. That's still probably the first thing I'll play with next time I head out.
I emailed JP a few months ago to see if the chassis would accommodate the WSM/SAUM line of cartridges, and they said they had built several rifles with that combination with good results. However, after trying mine the mags won't feed well at all. They're made to hold 10 7.62x51, but they claim they will also reliably fit/feed 7 of the WSM line. I'll most likely be getting an Alpha type 4 mag in the near future since they're designed specifically for the WSM's.
