Hello all
I got a thumper last winter and have started playing with it as weather allows. It is my first peep sight ever. I have been having trouble with blurry sight issues I hope to fix by going to single vision glasses.

I have been having vertical stringing issues with all my shots being low. I see no way to adjust the rear peep for vertical. Am I missing something or is the only way to file down the front sight or adjust my sight picture within the ghost ring?

I am hopeful I can fix the stringing by clearer sight picture and more practice, as I really don't want to scope this gun. I have adjusted my loads from min-max and all are low with a 405 cast and 3031.

I have to say it is a very fun gun to play with and I am glad I finally made the jump to a big bore gun!
