To confirm what tony posted.Thanks for that,I couldn't remember for sure.28" is for spine deflection.


I figured I better check my arrows ifI am saying that they are as close as advertised or closer.


Well out of the 9, 3-39's I have and USED for 3 seasons and have shot many targets and a few deer.They ALL checked dead zero runout when spin tested and the spine deflection was within .005,except 1 and it was .007.The spine tester was a crude one and I suspect if I had a good one,they might check even closer,but remember,they have shot deer and logs.[](I don't want to talk about that one)[:-]

They were all checked at 26" centers.

Use what you like,just don't get caught up in the numbers game.Just choose a quality arrow.Anything closer than .003 should be great for hunting.



My arrows were seconds,they were cut shafts and sold at a discounted price from the factory.
