MyKey,

Thanks for the reply and info. Nationwide doesn't seem to have a website, but I did get in touch with the dealer . He claimed they are made by Parker, but your info seems to make sense, he may not know anything about Nationwide.
The field points are 100 grain, and the shafts are 4560. Are carbon arrows the same as aluminum? They would be 45/64th inch diameter, and 60/1000th wall thickness?
EDIT
It seems you are both right. I called Nationwide, and they are right next door to and owned by Parker in Virginia. The guy on the phone, (who was very nice and helpful. What a refreshing experience compared to other phone reps for other types of products) said the total weight with the 100 grain field points is about 380 grains.
