2216 shaft epoxied and/or knurled to the outside helps them when you hit a rock face, or something like it! An inch of 2216, chamfered on the back end, weighs about 12 grains.

they are super shaft,very consistent in spine and weight,durable and tough.I am been using them for 3 years now and i prefere them much more than the GT.I would like to fid them in size 450.Most of the one I have destroyed were with Robin Hoods,or some missing against a 2"hard steel wall that I use to stop the bullets of my 300 Whaterby Mag.I had a couple browen by some 100# plus boars as well.They are still the arrow I like the most.

I got 2 dozen shafts coming as we speak.  Looking forward to using these.  I have the 250's coming.  Hope they work for me spine wise.  It was tough to decide 150 or 250 as I was splitting the diff.

Randy i don't know what is your poundage but for sure the 250 will help you in the elk woods.

Better than Beman MFX??? Who has used both shafts that can compare the two?  I love the MFX but have been contemplating trying a new shaft out.

I have what is left of a dozen- and agree they are tough. My only issue is they are prone to loss as I launch them into the woods past the 3D targets !!!

They work for me! I re-fletched a few, and still have 11 left from the first dozen. Lost one to a poor shot.

I have a 150 and 250 test shaft for a month now.  Don't know where to start...  Want to shoot 20+% FOC.  Many concerns... fractures, taking the insert out/in adding subtracting weight to get them to fly, crown dipping, broadhead alignment once insert is glued for good ect. 55lb BW 2018's w 145's currently. Anyone from Scguylkill County PA?  I'll be right over.  Matt

Been shooting 30" 250's with brass inserts and 125 gr tips.  Fly great out of my bows from 50-60#

I'm fletching a brand new doz. 250's rt now.  My 150's have been thru hell and back over the last year.  Great arras fosho!

I had awesome luck w/ my 150's, super tough but my Axis 400's are giving them a run for the money.....DB

I've done pretty mean things to those cheap CX arrows. They sure can take a beating...
