If a Bear aluminum arrow reads "50-65#", what number Easton shaft would match it if you mixed the Bears and Eastons in your quiver and shot them together?

Best way to know is to measure them.
The Easton code is broken down this way. 2018
20 = 20/64's outside diameter (OD)
18 = 18/1000's wall thickness. .018"
Measure your Bear arrows and see what they come out as. OR try some assorted shaft inserts and see what fits properly.

Somewhere on the Bear arrows ought say something like .320 for the older magnums or for the newer metric magnums 8.6, 8.7 ,etc. You can find conversion charts to easton numbers. I shot 8.7's which were 2219. The metrics were x7 alloy.

50 to 65 only means that you can likely use it for a 65# bow at 28", or 50# at full length..whatever that arrow length is...32" usually. They also base their numbers on a 125 grain tip. It's really a confusing thing and the carbons were noted for that early on before they started using deflection numbers. In other words, the 50-65 is mostly a worthless designation. Put them on a spine meter and check them versus a 28" span and 1.94 pound weight. By the way, the 1.94 was meant to be 2#, but Easton found that their weight was only 1.94...with skazillions of arrow shafts already out there, so they changed the weight from 2 to 1.94. Funny how that works.
With aluminum you shouldn't have any issues since they are already shown at the diameter and wall thickness spine. Any aluminum arrow chart from 1968 to present will be accurate for static spine requirement.
