But I will call myself an official member now because I just bought my first crossbow yesterday


I was very limited on funds so I had to go used, but I landed an Excalibur Phoenix with most of a light stuff package at a really good price. Color me excited!!!!
So I'm officially part of the excalibur crew now! Can't wait for deer season here in PA!
One question I have right away even before arrival- I don't know how to correctly measure bolt by grain weight. Can someone explain it or point me to a sight on how this is done? The xbow is coming with some new and some used bolts and I have no idea how to determine grain weights. Can I do this at home or do I need some kind of specific scale? Do I need to take this to an archery store to have this done right?
Of course, I will eventually buy a whole new set of bolts that are all grain matched, but until then I'd like to use what is coming with my purchase.
