Thanks guys.
The 6.5 RM's I've built have all shot well. When I had the 24x scope on the first one, I was shooting some nice 300 yrd groups with the 120ttsx. The loads developed on the first rifle have worked well on the last two as well. Same reamer, same barrels, same bullets, makes sense. 143 eldx and 120 Prohunters are good shooters as well.
I've only just broke in this mountain rifle and it likes the same loads so far. Half to three quarter inch three shot groups at 100 yrds.
I eventually will try another powder besides RL 22 but I have a pile of it and it seems to work.
I have no more .264 barrels so I'm done now. Finally. Thanks for listening!
And I agree, it's almost as good as a 270 Win.
