I shoot a guardian at 66lbs with a 29.5" draw. My arrow is 27.5" long, and are gold tip 5575's. I shoot a 100gr head with 2" blazers and wraps. Landons thread about KE led me to a site that cal. KE. I came in at over 77lbs. My arrow is just under 400gr...when given all this information does everything add up to 77 lbs of KE???
I need 2 things to calculate your KE. Arrow weight and speed. Here's the formula. (Speed x speed) x weight / 450240. My first reaction to your 77 #'s is to think that number is a little high, unless your Gaurdian is shooting them pretty fast.
Sorry Mobow, I forgot. She chronos at 304, before I added the wraps. I used the Archery Headquarters link from Landon's thread to get the KE listed and I also thought it sounded high. The arrow is right at 400gr and is moving at 304. Thanks in advance. I shoot 2 blade rage and have no issues with passthroughs, so maybe the number is close. I bought the bow from Matt (rick james) and she was VERY tuned when I got her. Edit: We dropped it down from 70 to 66 and I have not been to the shop since, can you "guess" how many FPS that cost me and still get a good idea of the KE? That 304 was at 70lbs, not the 66 I currently shoot.
I show you at approximately: arrow weight: 377gr arrow speed: 294fps FOC: 11.33% KE: 72.86 Your arrow spine shows very weak also.
Thanks gentleman, would a 125gr head help with my spine issues. When I was looking at the charts last year when I set the bow up I was borderline between 2 choices of arrows. I have mentioned several times in the last few months that my bow IQ is horrible, when I comes to things such as this. My best friend always handled it, from setting up bows to building strings...now that he has been in afghan for the past couple years, I feel like a DA...and I don't like that. Any input is welcome and wanted.
Thanks Scott, I did a little reading in between replies and I just read where making the front end 125 would be a bad idea. I shoot alot, and scout alot... but i guess I need to spend alot more time in the "classroom" if you will. Thanks for the help guys!!!!! I was out shooting to 40 and a little beyond today and everything seems to be flying good.
