The ability of 168 SMKs to reach distance is heavily dependent on atmospheric conditions.
Rifles Only is essentially at sea level. On a recent cold day, those puppies were going subsonic before 800 yards.
When a 168 SMK goes transonic, it often behaves badly, because the angle on the boattail is too step, and it may start flying sideways, which does not enhance accuracy...
On a hot day at Rifles Only, the 168s may get to 1000 yards supersonic - it gets <span style="font-style: italic">hot</span> down here from time to time...
For that reason, it's better to shoot loads with 175 SMKs, or other better behaved bullets <span style="font-style: italic">unless</span> you're a police officer whose department mandates use of 168 SMK loads. Then it would be better to train at Rifles Only on the department load.
