I had Pac-Nor install a 26" stainless super match barrel on a Remington SPS. They trued the action and put a Sako style extractor in it for me. It is chambered in 270 WSM and will toss a 140gr accubond 3300+ fps. Accuracy is about 3/4 moa with absolutely no load work, I'm still shooting the loads I used in the factory barrel. Once these are gone, I will tinker with it some to try get it shooting a little tighter. You can see it my icon picture. I would use them again, I think I would like the 3 groove on my next one.
