Nice gun...I have the same model, with the exception of a new barrel.
I tried those bullets maybe 3 years ago in that barrel. I didn't get to play around with the 115's too much. I shot them mostly at 300 yards, nothing spectacular maybe a 3 inch group here or there. But, my barrel was getting old and worn by the time I tried them. The time I tried them at 1000 yards I had trouble hitting a 30" tv.
There was a thread awhile back started by Redbone, Called 25-06 loads I believe, just do a seach on that.
There was a fellow on there, using your same model gun in 25-06 for 1000 yard factory class competition. He gives his load, and it seemed like a good one.
