My friend just bought a brand new Excalibur 380. He asked me to sight it in. Is is supposed to shoot 380 with the bolts and string combo that came with it. I changed the 150gr field points to 125gr and proceeded to sight it in. I shot the first shot over my chronograph it read 365, then next shot 361, then 362. I adjusted the scope to the measured speed and had it sighted in to 50 yards in the next couple of shots. It is extremely accurate but, louder than his old phoenix. It buries the bolts to the fletch in my target, it is nice.
