Excessive Down Pressure

Got my 380 fixed a few weeks ago and have had some arrow drag/burning smell. Rail is properly lubed. I know it's easy to install the limbs, so is there a way to adjust them to correct this?

Chris, I just had a thought. My arrow hold down spring had excessive downward pressure when I bought the bow new, I mean it was way too much, so I would check that, and also try to determine if the smell is coming from the arrow rubbing or the string. I know aluminum nocks can cause a gross smell. On my matrix 350 LE I had to pull up on the hold down spring quite aggressively till I felt the tension was correct.
Thanks kip it does seem like the arrow retention spring is a bit tight on some of the arrows. Ill try that.

The drag marks are parallel around the cock vane. I think youre right about that smell...i smelled the serving and it didnt have a lingering odor so it had to be the arrows.
Yeah chris, that spring on the excaliburs is very stout a lot more so than other bows out there . I had so much downward tension on mine it was crazy, I think I pulled up on it a bunch of times until I got the underside tip of it up off the rail just a touch. you don't want to get it too loosened up because then that could let the string jump the nock I'm thinking. happy thanksgiving!
Happy Thanksgiving to you too. That seemed to help a lot. But I just noticed my rail has a chip in it right under the tip of the retention spring. Also the finish has been dragged off on the left side edge of the channel. Both limb tips on my brand new limbs have cracks in the laminate. So I guess as soon as my Swat is fixed ill be sending this guy back to his friends at Excalibur.

Yup spring retainer is too stiff, it should only keep arrows from falling out while held downward. The deck issue tells me that its higher on that side the the other when they formed it at the Factory. I had to send one of mine back for a new one

That makes sense...I guess either way itll be getting swapped. But actually the whole xbow will with the limbs cracking as well.
Hate youre having all this trouble but atleast it's an Excalibur so no problems getting things replaced.
Chris, are you saying the limb tips that are glued on there have cracks? what kind of string material was the string made of? Just curious about the different string materials that we use and wondering which one I should be using. right now I have a force-10 string material, string on there and I love it but I did get a cracked limb a few weeks ago.
I am sure i made him a Force 10 string. Force 10 is a recommended material from BCY for crossbows
I do like the force-10, Blacktail, what is the difference between the force 10 and the rhino material?

I would have to go to Brownell's Site n read what they used to make the material. I will do that in abit
I guess I hijacked this thread, sorry, I found info that stated force 10 and rhino were very similar and made from the same grade sk78 material and both had a soft shot feel.

I don't think so, reason is some good info on string material was posted for members to read n learn
I have had my force 10 flemish from Mike and it has performed awesome. Just now needs a new serving around 300 shots.

@wolfer posted this image about the 380 explaining where he thought the problem might lie. I checked my flemish and it fits right according to it. I have a brand new string from Excalibur that lasted 60 shots on the serving. When I had it on my bow to mark the center of the new serving, the 2 loops were different sizes and one was obviously way too large. I had this string on after the repair, lasted about a third of the shots Ive taken. So just guessing it could have been an issue.

Also most assuredly investing into a silencing kit to help absorb some lim energy and ill steadily try to up the weight in my arrows too.

The Excal string was on more like 1/5 of my shots not 1/3

I have one of Blacktails force 10 strings on my Matrix 350 LE and I love it and took two bucks with it this season. One thing I'm curious about is possibly getting my next one with more strands in it to help curb some vibration. My bow isn't bad now but I read an older thread somewhere where wildcatter was using a 36 strand force 10 string that really quieted his 30 down, I have a 350 and am currently using a 28 strand force 10 string, I wonder if 36 strands would be too much for the 350.
I meant 380 excel for wildcatters bow not 30, lol where has he been lately anyways?
