A question for you fine bow shooters. I have used a couple of the Walmart Carbon Exacta arrows for groundhogs with my Threshold. I shoot a 29 inch arrow and the exactas are rated for 45 to 70 Lbs. I have killed two groundhogs with them from my Threshold with no problems. My question is can they be used with my new Nemesis? Both the Threshold and Nemesis are set at 60 Lbs. The arrows don't have any markings other then 29 inches and 45 to 70 Lbs. Thanks for any help on my issue.
