What does everyone point load their arrows at? I have some 55/75 that are new I foot them and got a new bow with less weight and would like to get some use out of them, but they are too stiff.
Has anyone point loaded over 300 grains? More like 350-420 grain point load? If so what were your results? Any danger in damaging the arrow somehow?
Thanks in advance
Ben
I use nothing but CX 350's, and I use a 260gr field point and a 100 gr brass insert. Total of 360 up front.. I always use a stiffer spine and load up the front. Arrow flies FANTASTIC and hits hard.
I am watching this thread close. Been curious as to how much weight you can put on the front end.
Currently I am shoot 300gr. on a Beman Bowhunter 400, from a 51lb recurve.
Been thinking about buying a sinlge shaft either a 340 or 300, cutting it to my length, then seeing how much weight it would take to get it properly tuned.

I've been thinking about going heavier up front myself, right now I'm shooting 100 grain bh's with 100 grain brass inserts and was pleasantly impressed with those results . . . but tis the off season, time to build a better mouse trap!
Great, I feel much better now. I'm shooting a Rose Oak puma hunter which is 58' and is 49#@28 but I draw to about 30.5 inches so it lands somewhere 53-54 lbs and my 55/75 with 250 up front is still spining too stiff.
I ordered some 100g brass inserts from big jims and have 145-300g points to test and see when they stop spining so stiff. I actually would'nt mind if they tuned with the 300's well, I would have around a 700 g arrow with a monster of a broadhead up front.
Thanks for the reassurance, looking forward to getting these flying right for me.
Counting external footing and brass insert point and adapter,my heaviest has 450 grs on the front end and total weight of 700 grs.They fly as well as any arrows I have but are harder to knock off course as in a heavy cross wind and I'm able to get away with less fletch.I have another set that are 428 grs on the front and 650 total.
We have had wind every day for the last couple weeks and as I was experimenting with using smaller fletch(3",4 fletch)I went out and shot broadheads several times when there was a very strong crosswind and they way outperformed another set that had 5" fletch.
In this area,if you don't hunt in the wind,you don't hunt much.
You can put about any amount of weight on the front that the spine of the arrow will tune with.They don't seem any harder or easier to tune.You just have to start with a much stiffer shaft and have a variety of point weights to try till you find what your setup needs.I normally cut shafts to 30" and tune by adding front end weight.I keep a variety of field points on hand from 100-300 grs and I can switch them out fast and get real close in a short period of time.
When I think I'm close,I add a 5 gr weight washer,then another and another till it shows weak.Then I remove them one at a time trying to get it to show stiff.Once I determine the head weight I go to broadheads and customize weight if I have to,using glue on head,adapter and can further fine tune by adding a few #6 shot pellets.
I shoot several sessions before I go whole hog in setting up broadheads and when things are looking good,I will try shooting them in a cross wind to see if I have enough fletch but not too much.
I have trouble predicting how much point weight I will need but the bow and shaft will tell.I also see a difference in point weights needed between same deflection shafts by different manufacturers.
The only draw back is,you may end up with a heavier overall arrow than you like for the trajectory you want.You just have to decide what that is.I first started messing with this stuff to build a set of arrows for a moose hunt.I found that out to 20 yds,I couldn't tell a difference in the heavy arrows.A little more drop at 25 and 30 but I adjusted quickly to that.Since then,I've been having fun tinkering with them.
Good ifo Jim! Thanks for sharing!

Onions,unless your bow is cut way past center,don't get 300's.You will have to put a boat anchor on the end.With a bow like that,cut to center,I use a .340,100 gr insert and 300 gr point.Using GT black shafts(7595)that makes about a 700 gr arrow.With Victory V Force .350 shafts which are lighter and a tiny bit thinner,I needed a 100 gr insert and 325 gr point.That arrow came out to 650 grs.If you use woodgrain shafts you will add roughly 30 grs more to your overall arrow weight.I stick with black.
If I drop down to .400 spine,I use a lot less point weight and end up with an arrow roughly 540 grs.
I put 525 gr up front , works great :0)
JimB thanks for the advice!
I think I will go for the 340 and see what happens.
Drewsbow > What is your bow/arrow set up that needs 525 upfront!
Thanks

Chris : I am shooting beman mfx 500 full length and 42 @28 whisperstik. I draw it to 31 and get close to 50 lb out of it . I add extra brass inserts up front because I use two long and one short one stiffens up the front. I have spent alot of time bare shafting and working this arrow up and it flies great and hits hard , total weight 840 gr.
Drew that is a monster of an arrow, I can't wait to get my inserts and 300g field points to see where these will tune.
I'll be doing alot of bare shaft testing, O and do you have any idea what your FOC is with 525 up front? Must be crazy.
Thanks for all the great info guys.
I get 30 % foc when I plug in the numbers .
Vyperkahn.. 51 @ 28
Victory HV 350... 28.5" arrow...400 up front...608 gn-total...32.4% FOC
