First two shots were around 265 yards, final shot was probably 30 minutes later after I went back to round up my gear. I left sitting on the rock I was glassing from, it would have been a 600+ yard shot from where I was glassing. I could probably have taken a 600 yard shot, but I was bleeding velocity and energy with the 130 gr TTSX and knew closer was the better option.

FYI if you run numbers you'll see my load at 265 yards is close to the same as your numbers at the muzzle of your .300 BLK.
