I got my string from Blacktail on here for my old wide Excalibur Vortex. I installed it set my brace height left it cocked over night. Took it out to day to shoot and was within an inch of poi of my old string. In minutes I was zeroed at 25 yards, tried 35,45 yards and was dead on with scope hash marks. Well pleased with my set up. Thanks for the advice guys!
