Arrow ?
 

Here's the low down . I'm shooting carbon express out of a Barnett Rhino . The arrow track is grinding or scraping the rear of the arrows . There are two grooves begining at the nock and extend forward about an 1" to 1.5" . Thus making the wall of the arrow thinner . Is this normal for a carbon arrow ? I think I'm going to switch to aluminum , even tho I prefer carbon for every other application . So - is it the arrow , the bow or the operator ? Thanks .

All of my nocks show wear, buy not the actual carbon. Is there something exerting force down on the arrow as it is released? Maybe the rail is rougher than it should be?
Carbon should not be wearing noticeably, not with normal use.

RE: Arrow ?
 

Sometimes the helical or the offset, cant remember which can cause it. The curve of the vane can push the arrow to the one side causing it. But this usually only makes a mark on one side, and never really a deep scratch.

I just had a thought - what if it's the nocks ? These are the half moon type . I've seen some flat ones - what are those for ,, and can I use them ?

RE: Arrow ?
 

Where did your arrows come from? I wouldn't switch to flat nocks until we figure out what the problem is.
Are your nocks sitting parallel to the rail? I mean, when the string rests in the nocks does it sit flat? I still can't see that wearing out carbon though..
Someone will come by soon that actually knows whats happening, I am guessing it will be GrumpyTom with the answer. Don't give up on the carbon just yet.

Only wear i have had with my Phoenix was from 11 degree helical 5" feathers. They would wear on arrow slot channel. I cut them back to 4" and no wear. OK Barnett users step up and answer please.

"Here's the low down . I'm shooting carbon express out of a Barnett Rhino."

The Barnett Rhino was my first crossbow and i fired it many hundreds of times with no problems. Killed some deer and hogs with it. Something is probably wrong with the track.

RE: Arrow ?
 

Do not use flatnocks in a Barnett! You may get away w/ it but eventually the string will jump over the arrow and it will result in a partial/full dry fire. Check your tiller [string square to rail] Minor rub marks are normal, but like said you may have a rough spot in track. Good luck, hope you figure it out.

RE: Arrow ?
 

It could be that your retension spring is pushing down too hard and only causing wear on the back part of the arrow. I agree, do NOT switch to flat nocks.

It could be that your retension spring is pushing down on the arrow too much.
I agree, do not switch to flat nocks.

Make sure that the bolt that holds the limbs on is tight also, I used to
check mine about every 25 shots when I was shooting my quad 400
Just a thought.

RE: Arrow ?
 

Well , my knocks are parallel to the string . The arrows have the facory fletching - It's probably a couple of degrees offset . The arrow channel shows wear - How ever the aluminum was coated/colored has worn off . So the arrow rides against raw aluminum (it feels pretty smooth but maybe the friction is too much ). Just a couple of questions -1- The arrow retension spring , ths is the small spring that holds the arrow down against the rail , right ? How much pressure should be on this? 2-Should your string should have a significant amount of downward pressure on the rail ? Thanks .

RE: Arrow ?
 

Are you using lube on the track?

RE: Arrow ?
 

How much pressure should be on this?

Excal calls for 1/4" between spring and rail. Should work for your bow, you can check by loading an arrow and kinda tapping on stock while you have it pointed down. Arrow shouldn't move forward any at all.

RE: Arrow ?
 

I'm begining to think that maybe it's operator error . I hadn't thought too much about rail lube . I have been waxing the rail , then buffing it out . And maybe not frequently enough . How am I supposed to be lubing the rail ? And how often ? Thanks .

RE: Arrow ?
 

Depends on the amount you shoot,I check mine about every ten shots.:)

RE: Arrow ?
 

Just wax the rail and leave the wax on. Do not buff it out.i wax the rail on my Barnetts about every 5-10 shots.
