Hey Guys, I just started shooting a bow this year and i shooting a 2012 Bowtech Assassin and when i first got fitted for my bow the guys gave me a Beman ICS Hunter 300. Now im looking at a spine chart and looking at the numbers and 300 just doesnt seem right...http://www.huntersfriend.com/carbon_arrows/hunting_arrows_main_custom_all_specifications.htm and also this as well http://www.huntersfriend.com/carbon_arrows/hunting_arrows_spine_chart_by_deflection.htm. Now i also owe you guys a little more information. I usually shoot with my limbs at 62-65 lbs and my draw length is 28" and the arrows are cut at 26 1/2" and i'm using 100 grain slick tricks and field points. Now to me with all this information it looks like i should be shooting a Beman ICS 400 or 340. So what do you guys think I should do?
If you're shooting 62-65 you can pull off a .400 spine. If you want to keep the .300 spine you can turn the weight up to 70 and toss a 125 head up front, maybe even a weighted insert for a very high FOC. If you're planning on switching up arrows, look at a .340 w/ a 125 head. You don't necessarily have to stick with beman unless you're brand loyal. I like to find a desired weight, 5.5 - 6 grains per pound and then choose the best fitting arrow. I personally like a heavy spine (.300), a heavy tip (125 with weight) and a lightweight arrow (under 9.0 grains per inch). This pretty much puts me at a >12% FOC and a 6 grains per pound arrow. They fly like darts and hit hard.
Thank you for the advice it makes more sense now that you have explained it like that. i might go to a 340 and a 100 grain head at 65lb draw Sent from my DROID RAZR using Tapatalk 2
It's easier to compensate for spine that is too stiff. It's all going to depend on what tuning tells you. I like to start with paper tuning for this. Just jump on if you have any more questions, lots of good info in the people here.
