WEll...truth be known.....my Savage 10 FCP-HS with a 24" 11.25 twist is sending the 150 smk,s out to 1K with consistancy and accuracy. I purchased the model K for the sole purpose of using heavier pills.....not that I really needed to because im already doing it with the lighter 150,s but because I wanted to and had money burning a hole in my pocket.......besides......I dont smoke....dont drink.....dont pull all nighters (anymore)....what the hell else Im i supposed to do???????
