I don't even know what NALRSA is...I'm guessing North American Long Range Shooters Association, and I could confirm it with Google, but I'm too many drinks into the evening to bother. The point of my reply is that the group posted by the OP is freaking amazing. The rifle is something to behold, yes, but that group could not be achieved by me with that rifle and exact load if I'd had 1,000 hours of practice beforehand.
Well done! This forum constantly reminds me that I have a lot to learn and even more to practice...think I'll work on that this weekend some.
