RE: Yes, another form thread.
The first thing that jumps out at me is the release is a MILE too long.You should be able to wrap your finger over the trigger without reaching for it.How in the world can you even reach it.Changing or shortening the release will help your shooting probably more than anything else at this point.
Second is the chin.Hold your head up and relax.You will have to move your peep but that will be beneficial.
1 more thing,relax the fingers.See how stiff they are.As a matter of fact,relax your whole body.
