The 150 ABLR might eat into powder capacity a bit. To 300 yds, I'd run the following:
150 PT
140 AB
150 NBT
One other option, the 120 Barnes, but at modest speeds, the above 3 will give you solid performance.
That's a good looking bullet but in my three 7x57s and a .280 Remington it's about useless. I'd originally on using that one in the 7x57 as a means of getting a little more range but accuracy has not been good. I keep trying different seating depths but the best I've gotten in any of my rifles is three inches. Guess I'll just have to go with the Partition.
