I have a savage model 10 that I put a 26" shilen #7 contour, 1-12" twist, select match barrel on, although I had put a few rounds threw the barrel it was with old 168 gr. loads I had left over and it shot ok. Finally I was able to find a box of the 155 gr. match bullets I wanted to shoot and wow is all I can say. My first batch of handloads for this gun produced consistant groups under a half inch, and one group at 1/4". I am very pleased, this was off a not so good rest with high winds. I know I can get the groups tighter with a little more work but am very happy initially. My load was 46.2 gr. of IMR 4064 in hornady match brass with federal 210m primers and 155gr. match bullets, I cant remember the O.A.L. off the top of my head.
