I appreciate your taking time to go thru your setup with so much detail. It is a great help for someone that has not experimented with internal weighting to achieve maximum FOC.
My questions relates to the weight of your broadheads (667 gr) and your practice arrows with field pts. Is there a difference and does it matter and what is your solution?
For example, are you changing the internal weights? If the Wensel is 174 gr. of the total 667 grains, what is the makeup of your field arrow and do you have to re-tune? I am thinking if you drop 125 gr. more or less the arrow is not going to fly the same. Answer anyway you prefer. Thanks
i'm VERY careful to match arrow weights. i weight all points, adapters, weight tubes, feathered and nocks shafts, on a digital scale. i can get overly ocd about all that. i'll grind the back or front of a judo and/or adapter to hit the right total weight. i haver every size and material imaginable of field points, judos, adapters. i even add a nut to screw in adapter to add 5-15 grains, if need be. my broadhead of choice is the woodsman, and *almost* all of my arrow testing is done roving style using judos.
ANYTIME you mess with arrow weight and/or foc, you will at least need to see what it's done to arrow flight elevation. that's a given.
if you think about upping foc, the best place is at the point itself, since that's furthest from the nock. these nail weight tubes add more weight behind the screw-in ferrule, so it's not as efficient as going heavier with the point, adapter, ferrule.
for example, these 660 grain arrows i just built are using 45 grain aluminum ferrules - i also have the same shafts set up with 100 grain brass ferrules, and loading one with a weight tube gets me over 700 grains (which, btw, fly just fine for me :D ).
it all comes down to what you wanna achieve. for me, that's first and foremost to up the entire arrow weight from my usual 585 grains. why? well that hog i shot in june used a 585 arrow tipped with a hair shavin' woodsman and it didn't pass through, though it did clip the lungs and tickled the heart. never found that arra, either.
so, firstly i'd like to go with a heavier arrow that i can control at hunting distances (up to around 25 yards). second, if i'm gonna add weight i want it up front to add to the foc. why? i believe foc aids in penetration and i love hog hunting.
the down side of added foc could be, and probably will be, a weakening of spine. can you and yer bow handle it? only you can answer that question. or, as one trad ganger has done and posted on this thread, use a weight tube AND a spine tube to both add foc and increase the arrow's spine.
interestingly, after LOTS of shooting with these weight tubes, i'm now beginning to believe they don't detract from spine in any noticeable dynamic way. but that's for each of us to decide.
