This thread is a week old but I thought I'd share. I have a 308 win. that has been shooting sub MOA with the 125 B-tip but I haven't been able to get it much under 1.5 MOA with a 130 TTSX that I wanted to use. It was the 2 close and one out as described in this thread. It has been shooting best at 2.780 OAL but after reading this I turned the seating stem down a turn and loaded three rounds at 2.725 OAL. Got a nice .9 group! I had only loaded 3 rounds so I came home and loaded 3 more then went behind the house to try and duplicate the results. Bingo! .85 MOA. So it does seem to work at times.
