Why do people install a 100 grain brass weight then screw in a 100 grain field point. Why not buy a 200 grain field point?
Just wondering and wanted to know what I am missing.
Part of it is to do with Tuning & FOC.
Tuning because a arrow that flies perfect bare shaft will be more forgiving with feathers in place during the hunt & sometimes a heavier weight up front helps bring that arrow ino the right tune for the shooter & bow.
FOC because the higher the FOC the arrow is the better it will carry at longer distance & penetrate into the target.
Now as to why have the insert then the point, well that is in part of flexibility to tune the arrow & in some cases have 1 arrow for different bows by just adjusting the point weight.
Now these are some of my reasons why I would do these things, I'm sure others more wiser than I will chime in & give a better explanation.
For me it is a simple "need to so"!
In Germany no field points heavier than 145grain are available. So that i can get a heavy arrow and dont have to order all field points overseas i use the brass insert. Also, in my experience the brass insert functions as a buffer for the shaft and makes the whole arrow a bit more durable. Just my 2c
I do it so that I can match my field point to my broadhead weight. They need to be the same, and I don't want to have to make up different arrows for different tips.
it's just another option for carb and alum arra building. it's all good and all that matters is getting whatever weight up front ya need for good arra flight.
that's the beauty of synthetic arrow shafting - the ability to tweak lots of parameters quickly and easily. much harder to do with woodies, particularly for bows with holding weights below 60 or 50 pounds.
I have alotta broadheads that are 125gr.I have found my bows shoot heads in the 200 to 275gr.the best on trad. carbon arrows. so by installing 100gr. brass inserts I can screw a variety of heads on and I'm right where I want to be wt.wise up front.Hope this helps. Gary.
What Gary said.
Basically if you have some 100gr. or 125gr. broad heads that you really like and want to stick with them, but you need 200gr. up front then the weighted inserts will help you achieve that. Then you don't need to ditch your favorite broadheads, just change to a different weight insert to get the correct weight up front.
There are also tunable weights that screw into the back of the insert and go in increments of 10gr. and up, so you can mix and match them to get the perfect combo.
it's all in the numbers and your requirements. i use both 22gr alum and 100gr brass inserts.
typical alum inserts weigh about 22 grains, brass inserts run 50gr and 100gr.
steel point adapters range from about 40gr alum to 125gr steel.
once an insert is glued in, the only realistic tweaking is via the adapter and point.
if you used an alum insert, and for whatever reason you required 300 up front, you'd use a 125gr steel adapter and a 150gr point = 300 grains up front.
i use the brass for a really heavy front end pig punchin' arra - gt hunter expedition 400 55/75 shafts, 100gr brass insert, 125gr steel adapter, 190gr tusker concorde = 415gr up front and a total 29.5" arrow weight of 680 grains out of a 55# longbow.
with that same arrow and 100gr brass insert, i can go down to a 535gr total arrow weight using a 45gr alum adapter and a 125gr broadhead.
so for me, the 100gr brass insert is pretty versatile and tweakable. i tweak the arras to fly well at the lowest build weight (535gr) and adding front end weight doesn't affect arrow flight at all, at least for me. but, ymmv.
i use em because the majority of shops in my area cater to the wheelie guys so i put 125 gr wgts behind the insert and can buy 125 gr broadheads all day long for a total of 250 gr which has proven to shoot the best on my 5575 gold tips
Thanks all. Kinda along what I was thinking.
Hey Ron+dog, Kinda offended at the wheelie guys thing, my nickname was from motorcycles! LOL
