Yukoner-
My NULA has a 26" barrel. My loads with 160 grain bullets don't exceed about 2850-2875 but that can be pushed a little. I'm using a 140 TTSX BT Barnes now and load to about 3,000, but that can also be speeded up a bit. I'm more interested in accuracy. Be cautious with some of the old data.I only use H4831 and H4350 now as I've had seen very good accuracy with them and they are more temperature insensitive than many other powders. Zeros don't change in cold weather. However, Reloder 22 and N560 will give you more speed.
