Got out to shoot a few rigs today, been a while since I shot but it went well. My 7mm Rem Mag with a 25" rock tube and 8.5 twist had wanted to shoot 71 grains of H1000 with 180 bergers the last time I was out. So I loaded 15 rounds and had 5 groups of 3 at different seating depths. To touch the lands in this long throat requires 3.505 with the 180 berger. The 3.38 OAL shot decently, 3.41 poorly, 3.44 a little better, 3.47 pictured below and 3.5 not so good.

Speed for the 3 at 3.47 went 2936, 2940, 2946. Again, this is a long throat so be sure to work up to that charge. If I can get it to repeat a few times, I'll be very happy. The Bergers do seem to be very seating depth sensitive.
