That is sure a nice group.

Most of my .260 shooting has been done with Lapua 139's over VV N-150. I found them at Powder Valley and have been very satisfied. The gun likes those really well. Having said that, it has a Shilen stainless bull barrel. We used the Lapuas at the Midrange Prone match at Camp Perry last year where we shot from 300 to 600 yards on the F Class targets. Every dropped point was caused by the shooter.

I had trouble finding 140 AMAX bullets last year, so I didn't do a lot of experimentation with them. The little that I did do with these bullets was very satisfactory. 120 AMAX worked well too.
