Here is a PM I received today. Good for all to know.
Ray,
I have been using a Mueller sight on my ten gauge now going on
the second season. I have had great experience with this sight until the other day,
I was setup on a coyote dead to rights but the dot disappeared, I was able to manipulate the controls and got a dim dot but the coyote was spooked and i didn't get a shot.
When i checked the battery i found the problem, there was three deep dents in the
bottom of the battery from the contact tips in the printed circuit. The battery mounting can't
handle the recoil, i would expect that the printed circuit will eventually fail from this kind of
hammering. Last year i used reloads that pattern well but are only two ounces of shot.
This year i have been working with much heavier loads, 2.5 to 3 ounce shot charges. a new battery solved the problem for now, its the first time i opened the battery compartment since i got the sight. Going to contact Mueller and see what they say.
Its been a great sight i hope they can help me solve this problem. Just a heads up.
Thanks, eight bore
