If your in your back yard spankin that target everyday then you must keep up on your string wax and rail lube. I only shoot a little just before season and then ocassionally during season andI only wax and lube before the season andI have no problems. My old horton was 13 years old and only replaced the string once and that was because my friends were harping on me about it not because it looked worn out. Alot of shooting on a dry rail will ruin them in a hurry, stop shooting and get the wax and lube.
