The 210's in my .300 Ackley (26" 1:10) are awesome. I'm getting good velocity and accuracy, so that gun and load combo (once load development has been finalized) should be a formidable rifle for hunting out to 1,500.They didn't do great at 1000 Br with an 11 twist. They would have wild fliers in the group. You are on the edge of stability. You would do better with a 10 twist. There is nothing wrong with the 210 Hunting VLD. It has a great BC and really kills. I have shot great groups at 1000 with this bullet. In my guns it prefers to be in the rifling about 10. I don't think you would see much difference out to 1000 or so. Matt
