My beef with the SMK in general and the 69 grainers + in .224" especially,is the sheer lack of terminal performance upon Critters. They routinely shoot nicely,but that is only half of the equation. Easy to match their precision and bolster terminal affects as well. Win/win.

AR mag constraints are a bitter pill to swallow,when it's easy to gun a 2.500" or better COAL in a boltgun and really make the upper echelon BC's sing.

I dote fairly heavily on the 75gr A-Max and it's .435 BC,via modest length barreled 223AI's and am especially fond of a 21" 1-8" 3-groove tube,which yields 3150fps with same.

A sinister combo to 1000yds +.
