My most satisfying (not on game) long range shot was made back in 1977 when my then new 7 mag was the only mag in camp and my buddies had been riding me about it.

We were in western Colorado and my buddy said can you hit the top of that dirt pedestal? I said sure, laid across the hood and held near the bottom of cross hair (guessing) and fired. About a full second later a puff of dust kicked up on top of the pedestal and I put the rifle down and continued packing to go home, as if it were intentional rather than lucky.
