I killed a few critters with the .30 caliber 155 Scenar out of my 308 Win. I did a test on a once killed Texas wild hog for comparison between the 155 Scenar and 175SMK. I shot soft tissue only and then one round of each type through bone (pelvis and front shoulders) at fairly close range (50 or 75 yards). The hog remained dead through all bullet testing events and I could really discern no difference between the 155 Scenar and Sierra MatchKing. Both penetrated the average size critter on broadside tests with obviously expected fragmenting on the 'through-bone' shots. (The hog was originally made dead, and the lucky recepient of the .30 caliber testing, with a 300 grain .338 caliber SMK at just about 300 yards (the 300 SMK did not stop in the hog, in fact it may still be in flight /ubbthreads/images/graemlins/smile.gif).
