Back weighting carbons

[xtrema312]

I want to back weight some Beman 400’s so I can add front weight to get a larger BH plus more overall arrow weight.  I would like to add 50 gr. each end. I want to look at options other than adding wraps and more feathers, or using the GT nock inserts and weights if they fit.  

I am thinking about cutting some brass off of some 100 gr. inserts I have that have bent threads and gluing them in.  What have you used for weights like threaded rod, bullets………… and did they stay in place?  How did you glue them and get the nock insert area cleaned up?

I never got the results I do from back weighing the carbons as I do with the front loading.  I understand it is supposed to be opposite, but all I got was messed up flight, similar to what I saw with weight tubes.

Thanks for the input Steve.  Do you recall your FOC with the back weight you tried? I can sure see if the FOC gets low you would run into issues.

try front loading to your desired weight and then shoot the arrows, I think you will be plesently surprised. this is for carbon only though

All I remember was  29.5 or 30" GT35/55 with std insert and 250g up front out of a 53# Super Shrew.

I have back weighted some axis arrows for my 85lb Widow longbow.

Used the 100 grain insert glued in past where the nock seats into the shaft.  

The weights stayed in place.  But, I really had to add a lot of weight to the front of the arrow to off set the rear weight addition. Plus.  I believe after watching some slow motion photography that adding back weight increases arrow flexation at the moment of impact.

Bottom line is that I won't do it again and i wasted several perfectly good shafts.

Hope that helps,

I think I will take this option off my list.  I may just go to the 3" footing and a little more point weight until I use these shafts used up as stump arrows this year.  Then switch to my GT trad's with more shaft weight as my target arrows and my CE250's for hunting.

I'M with J. Oles on this one. You want your arrow to be pulled through not pushed. TERM
