Yup, the large tennon on the SRS means you can go pretty long and still save decent rigidity. This started out as a 37" .338 1:13-1:9 gain twist 5R blank from Bartlein. I had it chambered with a .338LM Improved 40 degree reamer and then step & straight fluted to take some of the meat off of it. This was back in 2012 or so.
It shoots 300gr bullets at around 3100fps.
