Stop shooting them.. yesterday I was testing some 22 slugs. This morning it was raining and I couldn't help myself and installed my 177 barrel (checking my notes on the reg setting and HS adjustment for slugs) Later on this afternoon the rain stopped. I headed to my range to tweak it in. After sight in I began plinking my targets. Those little 177 slugs are definitely a whole new animal. I like them...I like them a lot!! Cheap enough to shoot too..After my little shooting session I headed over to the cow pasture hoping to pop a starling or two. Didn't see anything...darn it. Those little slugs make em POP! I'll bring the rifle with me in the morning and get a few then. I just can't get over how well a 177 slug preforms.
