[QUOTE="HandgunHTR, post: 3024034, member: 126524"] Got to the range again today to shoot my ladder of 250 grain Nosler ABs and 6.5 Staball powder. What I am seeing with this powder is that it is hard to get the SDs down and either I am at the low end of what it capable of, or it doesn't give the velocities that are reported. I was only able to get 2606 fps with the 70.0 grain load. I didn't have pressure signs, but that is about 150 fps lower than what this bullet should be going out of my barrel, based on what I am getting with the 225 grain ABs using N550. I guess I will have to try some H4350, H100V, and some N550 to see if I can squeeze a bit more out of the 250s. I did confirm the 2925 fps load of 71.5 grains of N550 under the 225 grain Nosler AB will be my hunting load for now. Was able to shoot a 10-shot group that measured 0.863". I took it out to 300 and printed a 1.974" 5-shot group. [/QUOTE]
