New outing with the Model 70
 

I had 9 different loads for the rifle today. Took a long time waiting to cool between groups. Bullets were 140 gr Nosler BTs and Barnes TSX. Powders were IMR7828, IMR4350 and Magpro. After sanding the barrel channel down to get the barrel free floating my groups did tighten up but not by much. Most groups were running about 1.25"-1/5", one load was too hot as the bolt was "sticky" and the primers flattened. But one load was right about 1" (60 gr of IMR4350). Next time out whenever that will be I will be playing with OAL and also trying some 130 gr Noslers.

Hope you get it to shooting well!
