Guys, keep it respectful, even if you disagree.
By the way I am shooting some 107 Smk's in my 22", I did a quick check of using a 105 Amax with 30.5 Lever in a 20" bolt gun, got an estimated 2782 ft/sec but pressure only slightly over the gas gun limit (52Ksi), depending on your OAL.
An Amax can be seated longer than the 105 HPBT's of Hornady, plus Lever gets real good MV without as much chamber pressure as other, more commonly used powders.
So high 2700's in a 20" bolt gun, not out of the realm of possibility.
