I shot production silhouette back in the early 80's before all the classes they have now,even pre .22 L.R.. Got away from it for way to long and just started back late this year with my son. Shot my first 40 today at Crittenden KY. Shooting UAS[ Unlimited any sight] with my Striker .308 and my 165 gr. hunting loads. That last ram was the hardest shot of the day , and the most satisfying.
