[QUOTE="goodgrouper, post: 134768, member: 2852"] I have yet to tinker with us869 but for the heavier bullets in a 300 ultra, it might be great. US869 is much slower in burn rate than powders I typically use for a 300 ultra, but because it is a ball powder it will fill the case much differently than extruded powders. This will allow for more powder to be used and velocities could rebound. Could be like using h870 in the 7mm mag. Velocities attained were higher than any stick powder could get within pressure limits. [/QUOTE]
