Had the Seneca out yesterday and had problems trying to zero it in. She was hitting way high. I have stock sights on it and the rear sight can not be lowered anymore. It is bottomed out. I was shooting the TC Maxi Hunter, 255 gr. bullet. I could get a higher front sight, but think the way to go will be with a peep sight. Any suggestions?

I remember the Williams and Marble tang sights. I have used a Williams on my 1886 Winchester and like it. It will give me more adjustments and should cure my problem.
