Yep good thinkin' on your lower chg wt and bbl lift.
I was a drag racer with the first bbl on one of mine. 99gr US-869, 170 class bullet and 3400+ fps. I went into very deep depression when the bbl went south @ a bit over 900 rounds. I felt worse about that than when I was told I had cancer.
However, a new bbl solve the remorse problem and kidney removal solved the cancer thing.
I'm no down to 94 grain 869 and just over 3200 w/the 170 offering.
We otta get together some time and synchronize the triggers and do a drag race thing.
Thanks for the explanation of the 3rd shot. Makes sense. The wind is your friend - yeah right.
