well, the idea is good, its just that doing it that way youd have to add quite a bit more weight to get the same effect and in my case I just dont want to do that...

I also want to add that IMO that FOC calculator isnt as accurate as itwould seem, or I should say I think its kind of deceiving... when calculating FOC it asks for overall arrow length, my 125gr thunderheads are a touch over 2" long but my 125gr field points areonly about an inch,and that one inchmakes a pretty drastic differencein its calculation,and I dontbelievethe broadheads weight is concentratedenough out at the tip to justify adding its extra length,which IMO gives a somewhat false calculation...



not having any brass inserts to work with at the moment I've been doing some rough figuring and number crunching and came up with some kind of surprising results...
my arrows as is weigh 438gr with 43gr inserts front and rear, feathers, and 125gr pointsand has a FOC with field points at a little over 12%, with broadheads its actually only a little over 10%(I dont know why but I never did checkitafter I got my broadheads, I've only calculated FOC with the field points)

with feathers and 20gr cut down inserts for nocks I have the back end of my arrows about as light as I can make them, which leaves adding weight to the front as the only option to increasing FOC... I've done some figuring and found that with the weight of the thunderbolt shaftsthemselves, thata 110gr brass insert and 125gr broadhead would only get meto about 18% FOC, and thats adding the weight directly to the broadhead, at the tip of the arrow and not 4" behind the tip of the broadhead,having to add all that weight to getto that FOC would up my overall arrow weight to around 485gr(if my calculations are correct... ), which is alot heavier than I want to go to begin with...were I to add the weight behind the insert I'd more than likely have to add quite a bitmore weight still to equal the difference in weight placement,which is where mycomment of not wanting to add unnecessary weight comes from, I'm going to have to add enough as it is...


I'd like to stick to around 440gr,but I would also like to up my FOC, and do it without adding a ton of weight, soI have somethinking to do to try to figure out how...I've said before that I didnt likeshooting 2213's, but I'm starting to wonder now ifgoing that route may be an answer...



I'm probably getting way too involved with this(like I usually do...)but I want to be completely happy with my arrow setup, and when I'm done putting them together I want to know that they're the best they're going to get, and I dont want to be left thinking I should have done something different...


but for me this is half the fun, and I have all summer...
