1177fps with a 124gr projectile is a tad hot for that powder. Pipe-bomb, catastrophic hot. 4.4gr of Titegroup is above recommended safe loads in any of my books or resource materials. That powder normally maxes out in the 1030-1099 fps range with 3.8 to 4.1 grains, depending on projectile and case volume.
I can get there with BE-86 but not necessarily on purpose.
