I’ve posted a lot about my journey earlier. I’ve posted videos of groups and shooting, a bit beyond 400 yards with the 6x45. I think I have shot it out to 750 yards on rocks IIRC. I recently played with some 95gr TMK and I got it up to 2660, but have not accuracy tested it. I got the 87gr vmax into the high 2700fps, but settled on a load at 2680ish. Killed a few deer with it this year that I’ve posted earlier. It did great, I just prefer reliable exits, but I’m not done testing the bullet on flesh yet. I would not suggest the 87gr vmax on elk sized game (yet) as I haven’t seen the penetration I think is required to reliably damage the offside lung consistently. This has been with a very small sample size and with no shots on flesh being over 90 yards, so my opinion is subject to change. I still need to cut a 95gr TMK in half to compare it to the 87gr vmax. They may not be different enough internally to make a notable difference in terminal ballistics.
A vmax at 3200fps mv does not perform the same as a vmax at 2600fps mv.
