Last night I cleaned the gun real well and made sure the scope mounts were nice and tight. Rechecked all my scope rings, etc.. Today I used Winchester 100 gr. sp with the rifle. Got it shooting very nice as long as I gave cool down shots, a string of 3 without letting it cool and you could tell a difference by about 2 -3". I had one bullet left and set a orange clay target on post at the 100 yard mark, took my time and put the round right through the center of the target!!! Did not shatter the clay target like I thought it would have just a nice hole right through it. If I can hit a clay target at 100 yards with it, think its going to make me a very fine coyote gun!!! Thanks for all the help and suggestions guys. Mike
