We ran the 300 grain SMK’s over 89.7 grains of Retumbo and got 2,760 FPS with no pressure signs. I’d start closer to 86 grains with the OTM’s and work up. YMMVWhat would you all think about starting at 85.0 gns of Retumbo with 300 gn Berger OTMs in a 30 Barrel with an additional 9 inches suppressed?
