Title: stiff arrows
Post by: rollin on May 12, 2009, 07:51:00 AM
I've got a problem with the arrows im using they are Beman ICS 400's cut to 29.5 inches and through barshaft tuning I have added piont weight up to 420 grains (100g. insert+125g. broadhead adap.+190g.field tips+2-5 g. weight washers)but they are still a little stiff. My question is are these just to stiff and should I drop down in spine? or should I continue trying to add weight somehow?thanks

Try adding another 50 grains or so to your point. I shoot axis 400's out of a 55# Black Widow psa. They bareshaft good at 28.5" with 100gr brass inserts and 125 to 150gr point.

Daniel,one of the problems im having is I am using the heavest insert,bh adapt,glue on point I can find, not sure how to increse weight with out modifing insert, or if it is worth it? I will say these do fly well and hit like a ton of bricks!

Adding more wt is not going to do it, if you are already at 420 grns up front.  Did you start bare shafting with full lenght arrows?  When bare shafting you should start with a full length arrow.  Someone else may have some ideas, not sure what else you can try.  You may have to step down to a 500.

I should have read a little closer. I had it in my head you were using 225gr up front. I would try trading the 400's for some 500's in the classifieds. They should tune alot better for you.

Waaay too stiff an arrow for your poundage & draw. If you short draw even 1" you're down to pulling 47-48# you will need 500s still with a min of 200 grains up front for tunable arrow flight for your mentioned setup! You can achieve a much more balanced setup by staying with a total arrow weight of 475 grains to 550 grains at your poundage.

Not to complicate matters, BUT I have a 53 lb Morisson Shawnee lb that shoots .600 with 250 upfront better than what I think Rollin should be shooting - 0.500.

Take you silencers off and replace them with half of what you had....it'll probably be enough to make what you have work....

Guru,took your suggestion and gave it a try today and it worked great thanks! Bare shaft hitting with feathers out to 20. I also think I will try out some 500's like you all suggested and do some comparing thanks to all.

Awesome another good tip I will remember.  I had never heard that one.  I imagine with that much weight the bow would be really quiet anyway

I would just like to add after shooting some more this morning to double check my results (which were the same), that there is definately more noise and vibration than before. I was using both brush bottons and string silencers. Also I am currently at the lowest recommended brace height with no arrow plate. The bareshafts are indeed hitting with the fletched but from what I have been reading the bareshafts should  show slightly week which brings me back to my original problem of needing to add more point weight or a drop in spine also I would like use  a arrow plate and sliencers which will further stiffen the shaft. The good news is after using the search button and reading up on efoc (which if I did my calculation right i'm sitting at 31.35%) I found something called Woodyweights that are used for wooden shafts, they from what I have read on there site can be used with a broadhead adapter too. They basically sandwich in between the broadhead adapter and the broadhead or field point and come In many diffrent weights! Im guessing I will need another 50 or so grains to set everything back up as before and I think these are just the ticket. I know that this is going to make for a heavy arrow with alot of weight foc but they do really fly great and what is the big deal if I lose a few feet per second? A .223 round moves super fast, but as I was told in boot camp by the DI/range instructor "this round can hit the nee and come out the top of someons head" ie.low weight high speed. On the other hand the heavy speer is the exact opposite ie. high weight low speed. Both will get the job done as they both have both been proven over time.I think im still going to try some 500's and compare them to the heaver/slower 400's and test them head to head for penertration.I just got a fealing the 400's are going to come out on top.Sorry for being so long winded any thoughts, comments, concerns?

Raise your brace hight to the highest recommend. this will weeken the arrow. I know i sounds backwards but its not. Raising brace will make arrow show week.
