James, no luck with the 115 bergers, but the 115 dtacs shoot lights out in my 243AI...that said, build the 6-6.5x47 lapua. I am a big fan of this case. I have it in the 6.5 the 6 and have another 6 and a 22-6.5x47 on the way. Should have both within 30 days if I know Mr. Don and the reamer for the 22 arrives.
I admit that I know just enough to be dangerous.....but dangerous at ever extending distances.
