This post is pretty long, and I apologize, but I'm hoping you guys can help me, just as you already have in responding to other people's posts. Yesterday I went to my local pro shop to buy some arrows. I've only been shooting about 6 months, but since I'm not putting arrows into the weeds anymore, I figured it was time to get rid of my cheap Wal-Mart arrows and get something better. I'm shooting a Hoyt Defiant, set at 59 pounds with a 29" draw. My arrows are a mix of CX Terminators and Wolverines. Tim, the local pro, had me shoot one of each through a chrono. The Terminator hit 268 fps, the Wolverine 261. He cut a CX Rebel Hunter for me and I shot 261. Kind of disappointing, since that was on my short list of arrows. He had a CX Maxima already cut, so I shot it and it hit 281! Now we're getting somewhere, I thought. We weighed the arrows, with the cheapos weighing about 440 grains (with 100-grain points) and the Maxima about 390. So far, it all made sense, except for the cost of the Maximas. Here's where it gets weird. I asked Tim to bump my draw weight up to 65 pounds, just to see what would happen. I shot my two arrows and a 6075 Terminator Lite Hunter (another short list item) that Tim cut for me. Not only was there no change in my arrows' speed, but the Terminator clocked in at the same 268! We weighed the Terminator and it weighed about the same as mine, although it should be a bunch lighter. I left there with no arrows and, what's worse, no clue about what was going on or what I should do. Tim said they're going to be getting some Gold Tips in soon, and thought maybe I should shoot their Ultra Lights, like he does (at 332 fps!). I assume there's some logical explanation for what happened, but it escapes me. Do we have an instrument problem? Shooter problem? Wrong phase of the moon? Again, as a new archer/bowhunter, you folks have been invaluable to me. I'm already a better shooter because of the advice you're so generous in providing. Thank you!
