Re: .260 load pressure problem
The barrel has had 330 rounds through it so far, and had a proper break in done when it was new. The gun has been looked over a couple of times, and there are no issues with the 'smithing. I've even checked loaded and fire formed rounds for concentricity and all appears to be good. With all the reloads I did for it I had no problems with pressure, but wasn't that satisfied with the accuracy hence I went to the load development guy for essentially a "second opinion"
He said that he found it difficult to get to shoot well initially but later discovered that with a higher magnification scope (that he fitted it for testing) he noticed a lot of movement of the rifle in the bags when on the bench. He put it down to its light weight (7 1/2lbs) and the thin forend on the mcmillan hunters edge stock. He said the movement on the target wasn't perceivable when using the 3.5-10 scope I had on it, but was definitely noticable with the 6.5-20.
He said that he then got it shooting consistent 1/2 MOA groups with 140 A-max's, so I ordered 10 rounds to get me hunting until I could load some with his recipe. And that leads to the situation to date.
I'm basically no better off, and am wondering what to do next..... I've pulled the heads on a few of the suspect rounds and turned 0.002" off the necks and put them back together.
I was really hoping to not have to be back in the load development cycle again as the rut is approaching and I want to be out hunting and not mucking around at the range.....
Has anyone else been in the position where the lack of confidence in their rig gets to the point where you feel like just throwing it in the creek and buying starting again? I used to be able to shoot awesome groups, but for the last four years of owning this gun I've hardly managed a couple...
