Gain twist
I have had a Ron Smith 26 in.18-9 gain twist on my 7STW for several years now (about 8, I think). It has been exceptionally accurate and handles bullets ranging from 140 TTSX to 180 VLD's with absolutely no pressure issues with any max + loads I have used in that barrel. It has had a few hundred rounds thru it and still shoots sub MOA with 180 gr VLD bullets at an MV of
3060. That may be due to the gain twist ..not sure, but I'm inclined to think so. One thing I do know is that there is not a down-side to using a gain twist in barrels of that length.
