arrow question?

[sam barrett]

I have a 48lb and a 52lb r/d longbow and I need some new arrows.  I really don't understand arrow selection very well so I have a question for you more knowledgable folks.  Are those weights close enough to shoot the same arrow shaft.  I don't mind playing around with point weights and what not, but would like to shoot the same shaft if possible.  Gold tip 35/55 shoots great out of the 48lb bow.  Would those arrows be too light or weak spined for the 52lb bow?  Would gold tip 55/75 shafts work with both bows or should I get different shafts for each?  Thanks for the help, Sam

What is your draw length in relation to the AMO. Are you  @28 (draw)with both bows.weights that are marked on the bow may not be actual weight.especially at your draw.Have you shot your 35/55 out of the 52lb bow?and when you do how do they fly? And we need the make and specs of both bows to really get you the advice you need.

Are they the same bow model or from different bowyers?

It'll mostly come down how close to center the bows are cut.  Even if they are the same model, you can build the sideplate out slightly on the 52# bow to compensate for the higher draw weight and shoot the same arrows.

Lots of variables.......miss marked weights, different risers etc. You gotta play with it a bit. Often if the center cut on the bows is the same you can build out the side plate of the more powerful bow to get them shooting the same.

I just asked a question about arrow selection and was directed to the STU calculator

You could stick in your current arrow set up and then both your bows and see how close the suggested spine is. If they are close you could most likely get away with just altering the point.

I must say thanks to that calculator i know which arrows will work with my bow and how to set them up without having to do a bunch of trial and error.
