Re: Lapua Scenar 155 grain for 308
[ QUOTE ]
I will also try the Nosler 180 grain BT's at 1000 yards and see how they group. They're great at 600 yards. But they appeared to go subsonic on me at 1000 the last time I tried them. MV was around 2600 fps on that 1K test. Next I'll be testing them (perhaps tomorrow) at 2725 fps. The Nosler BT's claim a BC of .500, but I'm not so sure...

Dan, I have had rotton luck with ballistic tips at 1K from the 308. I think higher velocities such as that from a 300 mag is better. I have found that the .507 BC is fairly close at least to 600 yards and it might change after that but there is somthing about those plastic tip bullets that makes em keyhole or tumble when they slow down quite a bit even if they are still slightly supersonic. By all meens try them again. You may have much better luck than I have had.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
