Picked up some 500 spine black eagle classics and a rug rest to replace the felt rest that I wore out. Arrows cut at 29" with a 200 grain head with the standard aluminum insert. There is a heavy wear mark on the outside of my rest. And little to no wear anywhere else. I am getting goofy arrow flight up close but it stabilizes at distance. So I do believe I have a weak shaft. With that being said...has anyone else seen this type of wear far out on the rest like this? Thanks!

I think you will find it is actually a shaft too stiff.
If you think they are weak have you tried a lighter point? If the arrow straightens out cut some off and put the heavy one back on.
Fletch scrape?
seems to me that if that was from the shaft you would never get an arrow down range...think its from ur fletching :dunno:
Id say fletching scrape. I have similar going on. Never had it until I switched from 3 to 4 fletch.
Might try rotating your arrow nock a little. Mine are glued on aluminum, so not really an option for me. Don't use that portion of the rug anyways.
Thanks for the input. I initially suspected it was due to fletching contact. But I replaced my rest for a 2nd time and oriented my fletching as such to ensure I wasn't making contact in that spot, and again that same spot wore down. I also know it's the shaft causing this because the length of the shaft is wearing the glue from the rest where it wore down. This is probably 50 shots worth of wear.
Wrong arrow spine I think you are to week . You didn't say what # your bow is. With that arrow with 200 gr. and 29" may be 40#s or a little less . Try a 400 and check your nock pt . start 1/2" above square .
I also should add that I was shooting Beeman Centershots 500 with 145 grain tips previously and they shot pretty decent. I put my new 200 grain tips on the old beemans and they still had great arrow flight....
My apologies. 44# but at my draw it's more like 42
Narrow your rug up beyond the wear point and put a toothpick under the rug, creating a hump across your shelf.
Raise the nock the same amt and see if you still have erratic flight.
I have found that putting too much pressure on the string with my bottom finger(3under) will cause me to have the arrow hit the shelf with some bows.
Try one thing at a time, thats half the fun is getting them tuned to perfection.

I used to use standard 3 fletching for years and always got shelf wear on the outside of the shelf. I switched to 60/120 degree 4 fletch and haven't had a problem since. I read that that it is the fletching pattern that Roger Rothharr uses, I know it works well for me.
That type of wear can be the result of to low of a nocking point. Raise your nock and see if that helps.
Could actually be caused by any of several things (my opinion only), including nock point too low, arrow fletch front surface is rough on one or more of your arrows and rubbing right there or your fingers are causing a torque on the arrow at full draw, causing something similar to low nock point.
A lower than needed brace height could exaggerate the above. Again, my thoughts only.
That set up sounds reasonable for spine. With the arrow flight you mentioned I'd start with your nock point too.
My brace height is set toward the high side for this bow and my nock point is pretty close to 1/2" above center. Still I am having this issue. I will need to buy a new rest to truly verify if things aren't changing cause this one is now wore down to the shelf of the bow. I'll try a lighter point and see if it helps as well.
If you are shooting split I would set my nock at 5/8 high
If three under I would start at 3/4

I would say too stiff and nock point too low.
nock point to low, just had the same thing raised it up and it stopped.
That wear spot is where your 4:00 position feather is passing the shelf as the arrow starts the archers paradox. All my personal bows get that wear pattern and have for 20 years. I minimize this contact by rotating my nock so one feather is at 3:00 (facing into the side plate). Some people call it cock feather in.
This is normal on a properly spined arrow. The arrow flexes on release and the tail end of the arrow passes 1/4"-3/8" from the side plate. Search for slow motion videos of the archer's paradox and you will see this.
I will also add that your shelf is wider then it needs to be. As mentioned earlier you can put a piece of a match stick or leather under the rest that is shorter then the width of the shelf, thus is a sense making your shelf more narrow. Hope that makes sense.
Thank you
