Trophy hunter .260 with siarra 107 gr not grouping

[foxx]

thanks, darkker.

I did find 140 Hornady Match at Midway. (Had to order 500!) Unfortunately, I did not try Midsouth soon enough so I will be stuck with these for a while.

I should not have said I could only find Sierra 107's. Obviously, there are others out there. What I should have said was I could not find what I was looking for, an affordable target-grade 140. Also, lacking experience with .260, when I got 107's, I did not know whether they would shoot well or not. I still do not know. The point of my post is to solicit other opinions about the bullet. Maybe its me. Maybe the rifle. Maybe the scope. Maybe the bullet.

I am trying quite hard on my loads, thank you. As stated, I tried several powders by shooting 4 shot groups, testing in .5 gr increments. The only decent group was 1 inch with Benchmark. Out of desperation I tried different seating depths with my one decent load. Changing seating depths only made matters worse. I don't think that is trying to do too many things at once. Actually, I believe that is SOP. Change one variable at a time, compare results.

Until now I have enjoyed what I consider success with all of my mass produced factory rifles, as explained in my original post. Better than most, from what I can gather. Maybe I have just been lucky.

Oh, well. I will try the longer/heavier bullets and see what happens.

Thanks, again.
