Shooting last night I experienced a loud BLANGGGG! after one of my shots and the arrrow landed in the dirt below my block. After exeriencing imediate shock because I just received my new limbs just over a week ago I immediatly started inspecting everything. couldn't find anything obviously wrong with the bow so I went to examine the arrow planted in the dirt and wouldn't you know it the nock was split in half. Carbon Express Terminators. Has any one else had any issues with these? Does anyone know if this can damage my bow, it sounded awful. The nocks are very tight right from the start but then loosen up after you shoot them for a while. I've been shooting all day today and the bow seems fine but am not very confident in the carbon express nocks.
