Obviously my 8" twist 7WSM has no problems with the 195, though my 9.5" twist 7-08 won't stabilize them. They keyhole at 100 meters from that particular barrel. I wonder if the 180 ELD will be enough shorter than the 195 Hybrid to stabilize in that 9.5" twist 7-08...


It seems like manufactures don't publish bullet length with the same discipline with which they publish BCs, so I use an estimator, which came up with a length of 1.620 inches.

As a reference I entered the values for the 7mm, 175 grain ELD-X and got 1.550 inches and the actual length is 1.567 inches, so the actual length of the 180 grain could be a bit longer; maybe 1.637.
