When I read HRL response I sald to my self, self don't respond but here I go again. Jerry, you are a shooter and for the last 10 years, you used your favorite double barrel and it gave you the results you wanted. Then all of a sudden it did not and you mentioned to a friend what happened and he said you need to go to a single barrel. So you said no it served me well for years and I still want to use it the way it was because it was ok for 10 years and there has to be a reason that it has changed. I know I am using more ammo to get the same results but I will keep checking to get it back to the way it was.
