saw a article the other day on how action screw torques can effect your groups

So I did a little experiment today on my 110 action based .204. These were shot at 200 yards using 32 gr Sierra blitzkings and RL10 powder .020 off the lands. Wind was about 5 mph from the 9 oclock position and these pics need to be rotated clockwise 45 degrees (the www. targets logo at the bottom)




as you can see at 30 inch lbs on the front and 5 on the rear I had a long horizontal string, increasing to 10 inch pounds it went vertical and at 15 began to tighten up then at 20 I shot the 7 rounds I had left and they were all over. Next week I am going to fine tune it a bit more
