I've only owned one longbow in my lifetime and it was a right handed 68" Belcher "Longhorn" hybrid longbow.
Every shooting session, the first arrow shot would always be 6" to the left. After a few more shots, the arrow would go where I was looking. But, in a hunting situation, the first shot is critical so I never took the longbow hunting.
I just never could get used to the grip.
I tried to correct the situation for two years. I could never correct the first shot problem so I sold the bow to Pinelander on here.
