well after destroying the FMJ bolts last year I thought I'd cut cost a bit, I don't want to cut quality. I did shoot the Black Eagle bolts and they shoot fine. I did learn that 1/2 moon nocks and flat nocks do not shoot to the same spot. The Excalibur requires flat nocks and my learning curve is a bit slow these days so flat nocks it is. I also thought the FMJ dent rather easily. I lost every bolt that I hit deer with last year. I was hoping that in a complete pass through the bolt may be cleaned and used again?? I still have time to decide on what I'll shoot this year but probably won't be the FMJ's. Look up Black Eagle products and let me what you think.
