HuntAway,I have a suggestion for you,its some thing I do when I am getting ready for hunting.
The next time you shoot after the second shot clean the gun real good with akl. and ww cleaner and leave it open to air so the inside of the barrel can cool in the shade[it cracks me up when I watch some one shoot with the sun heating one side of the barrel], walk down to the target and mark the number of your shots and where they hit make sure you take enough time for the gun to cool back to the temp. it started out at[to duplicate hunting conditions] then see where that next shot would go if you were in hunting conditions.
