Me and a friend played with Grendel sub-sonic loads a year or two ago. We used Hornady ELD-Match 147gr over 10 grains of h110 and CCI 400 primers. Chronoed about 950-1000fps if I remember correct. It got cold and haven't revisited it since. I built a 300bo bolt pistol recently and in hind sight, I wished I'd of did a dedicated sub-sonic 6.5Gren instead.
