270wsm matrix 165 testing
Well i was finally able to get out and shoot some of the matrix 165gr.
Tikka t3 270 wsm
26" barrel 1-9 twist
I loaded from 64gr - 66.5gr. 100yds my best groups (sub moa) were 66gr, 66.3 and 66.6gr. I havent noticed any obvious signs of pressure, but im going to measure brass bulge etc..I didnt have my chrono so im not sure of fps. im going to load up some above 66.6gr, i would like to find my max load.
