I was wondering if anyone knew what size Aluminum shaft you would us to foot  a goldtip Warrior 500 spine

2117's should work for them

Watching this as I also shoot some warriors....have had good luck w them despite them being a more economical shaft.

This site is a pdf with all common aluminum inside diameters.

Thank you very much for all the help

Looks like the gold tips are .290 and 2117s are .2941.  they should work well.  I use a reloaders chamfer tool to bevel inside and outside of the alum footing.

Not a bad idea I was try to think of a way to taper
