First, thanks to everyone for answering all of my many questions!
Was finally able to shoot today. Took both 06s 1 bolt 1 semi-auto.
For the bolt I had 165 hornadysps loaded up with various loads from 54.54.5 ,55,55.5,56,56.5,57.57.5,58grns of IMR4350 ( i know 58 is hot) nothing realyy patterned well. 55 grains produced about a 2 in group.
On the other hand the semi auto I loaded same bullets with various loads of IMR4064 and I had beautifull 1.5 inch groups with 3 different loads.
I never tried any of the IMR4064 in the first gun. Didn't load enough.
Is one powder superior over another powder in certain calibers?
