A friend of mine just gifted my son a long bow and a recurve. The long bow does not have a string. I know next to nothing about archery hunting. How to i figure out how long of a string the bow would need? I plan to make a trip to the nearest archery shop ( about 50 miles away). Just wasnt sure if there is a formula to figure it out. The only marking that the bow has is that it is 52". Thanks for any help guys.
