Hi, I'm new to the forum. I've been reading it for a while but this is my first post. I bought a new Bowtech Destroyer this year. At the time I asked the guys at the pro shop if my current arrows would work with the new set up. They said yes they should be fine. Now I would like your opinion. I have the Bowtech Destroyer 350, 70# DW, 29 in DL. The arrows that I am using currently are Carbon Express CX300, 27.5 in long with 100 gr tips. Should these work or should I look at changing something (arrows, tips, etc)? Thanks, Mike
A couple of thoughts......... At your current setup, those arrows are likely to be VERY weak in spine. In addition to this, that bow is likely shooting those arrows at a speed that is going to get a bit crazy with broadheads on the arrows......your probably in the 320 to 330fps range depending on the state of tune and exact poundage and draw length. I've tuned well over a hundred bows for hunting setups, and crazy stuff happens when you get over 300fps. I'd personally setup a heavier arrow with the correct spine that will go roughly 300fps or less. Carbon Express is one of those companies that uses weird numbers that don't really correlate with the actual static spine of the arrow. A CX Hunter 300 is actually a .370 spine. You really want to be somewhere around a .300 spine. I've included a screen shot of the spine match chart from OnTarget2 for your exact setup below. I personally would suggest a true .300 spine arrow for your setup. You can go with any brand you prefer, but I'd personally recommend a Victory VForce V1 .300. If you don't want to spend the $$$ on their V1's you can go with the V3's and still get a decent arrow if you cut evenly from both ends. With the following setup, you would be setup perfect. I've included another screen shot below of my recommended setup in OnTarget2. Victory Archery VForce V1 300 - 28" Bohning Blazer fletchings - 125gr points Destroyer 350 - 29" dl - 70lbs Roughly 450grains, and 305fps with this setup
Thanks for the info Rick. And just to let you know, you were right on the money. I as able to sight in my field points, then I switched to my broadheads (100 gr Muzzy) and they were consistently ~4 inches to the right of my field points. Now I have another question. If I turned the poundage down on my bow would this help the problem? Or went to a lighter tip? Or a combination of both? Thanks again, Mike
Turning the poundage down would correct the problem. I would not go to a lighter tip, no need to and 12%+ is a very good FOC for hunting.
Sadly, in all honesty, those arrows aren't going to spine well until down below 55# with that bow. Cam aggession makes a big difference. You look at a force curve, and it shows you the stored energy that the bow has while at full draw. That particular bow has a LOT of energy, and delivers a LOT of energy, requiring a STIFF spine to tolerate/absorb that energy. While you'll end up with a slower arrow when you go heavier and get into the RIGHT SPINE, you'll also make your bow more efficient (the heavier arrow will absorb MORE energy) and quieter, while also be much more "tune-able!!!" Good luck with it.
I would take a whole turn out of the limb bolts and see how the BH's hit compared to the FP's. If they still impact to the right start making quarter turn adjustments on each limb bolt until they hit together. If the BH's hit to the left after doing the initial whole turn on each limb bolt then I would turn each one back down in quarter turn increments until BH/FP impact the same.
Thanks, I will try that. I will probably buy new arrows at some point, but if possible I would like to make this set up work this year. If I can't get it to tune properly I will just have to bit the bullet and get some new ones.
Well I had to buy new arrows. Broke some and lost one this weekend when I shot a doe. I just wanted to say thanks to everyone for the replies. Especially Matt. I followed your recommendation and went with the Victory V-Force V1 arrows with 125gr tips. They are shooting great. Now I just have to put the broadheads on and get them to shoot just as well. Thanks again.
