Cayugad,

I scoped my mountain rifle primarily for the light gathering qualities. It's only been recently that I started this quest to extend range. So far, the only bullet I've found this gun really likes are the Sabertooth. I'm pretty certain I'll be delivering 6/6 on 6" circle at 100 yds. soon with the 270gr. and 90 RS. See my post from a few minutes ago about my lack of success experimenting today.
