Thanks for all your pointers. A little clarification on my "problem."
I don't drop the arrow off the shelf-this does occasionally happen when I tense up my "draw" hand, but it is not a major malfunction.
I am canting the bow, normally, about 5 degees to my right side. This is where I seem to shoot my best. If I hold the bow vertically, as I do my recurve, my accuracy is not as good as when I cant the bow.
The "problem" is "training" my brain to hit the same cant consistently, ergo, the spirit level idea.
The pointer about changing the cant angle to practise hunting conditions makes a lot of sense, as I don't think deer will always be perfectly broadside, stc. This is something I will work on.
My point of impact change, is usually 4-6 inches from my normal aim point, this, to me, isn't acceptable accuracy (18 yards) for ethical hunting accuracy. If I can trim down the impact point change to 2-3 inches at the same distance, I will be a happy camper..er hunter.
Thanks again for all the idea's and suggestions.
Jim Godden..ain't you supposed to be chasing swamp donkey's ? Git out there after them long noses!
Have a great hunt!
