i was decocking and.......WTF !!!

[Onetimeonly x-->]

its not like I am new to this.........
always used to grab and pull the string back on my 3 other excals.

but this beast m380 has to be let down with the rope...
I never trusted it anyway

this is the bonified Excalibur cocking rope bought new with the matrix 380
last year.

it happened the second I pulled the trigger.

anyone experienced this ?

i'm inspecting my 380 for any damage.

all I know is my hunt was done

check out the chunk of roller missing on the complete hook.

and yes !!! hooks up, so I could see the string placement in the hooks



you can bet, i'll never do it again !!!! i'll shoot a junk arra in the ground

gendoc, which hook is the damaged one? Would it be on the same side you pulled on to decock? Just curious.

[strum]

I wonder ?..how old was the cocker?
not saying yours is old but they do need to be checked out regularly. from use they get tossed around quiet a bit and we don't think much of it but that heavy hook on the end of a rope can smack the table /shooting bench or whatever pretty hard.
also John you may not know your strength and just pulled em in two

the broken one came from the right side...I hold the t-handle in my left hand.

hey strum, I got it with the 380 last year.
maybe 50-75 shots.

I check it regulary, and i do the 16oz curl quite frequently, so maybe
my strength is the reason........... I kinda doubt it

No good hope bow is ok

I'm wondering if maybe the string came out of the groove and possibly rubbed on the scope mount causing it to break? I have seen that happen before when cocking, and if it would happen when uncocking the string could very easily break.

Just a thought

That is very odd. We get very few issues with rope cocking aids and I have been uncocking 405's with no issues. If you could send us the rope and hook I will send you a new unit. I want to take a look at the hook and the rope to see why they failed.

Something cut that rope, clean ends dictate that. A rope that snaps due to overload/stree does not look like this. The hook broke when rope let loose and clip hit riser is my guess. Now, what cut rope is another whole question that begs an answer but may never be known. It could have been nicked in process of manufacturing rope. It could have been nicked during manufacturing of the cocking device, could have got nicked by broadhead.....

Will do,
Your email to me did not include your mailing address
You sure i should not send my complete bow in ??
waiting your reply........

well, all i know is that I run the rope thru my fingers everytime I use it to cock,
and also did when I decocked.....if I had experienced any flaws...it would not be
used.
always its been 1st class condition and never around a broadhead or anything sharp.
and it did not come in contact with the metal systems above the groove.

and as nyexhunter said,

"You may be on to something with your theory.
My matrix had a ridge in the middle of the groove where the rope cocker goes. It looks like that is where two sides of the stock were put together. The ridge looked like it would be sharp against the rope so I sanded it down to make it smooth. It took the camo paint off as well, however, having a small bit of white in this spot is no big deal to me.nyexhunter"

I looked at that area and I do have a protrusion in the groove
located in the center.

maybe that's the culprit....

I can remove it easily. and I'm not concerned about the rope cocker,
its nickel and dime.....

what i'm worried about is my riser and limbs !!!

I guess I need to post a pic of my riser so yall can see where the hooks
impacted both sides.



if you can't see them, then you know nothing about these crossbows.


and what about my limbs ?

the reds do have a pretty good indention and the string now is pressuring them.
where they were between 1/8 and 1/4" away.

I just don't want my $1k matrix 380 to go tits up on me.
sorry if you don't understand.

John, any signs of fraying (or more precisely, chafing) on the rope near where it broke? Uncocking is a lot harder on the rope than cocking because it slides along the groove in the stock and the friction accelerates wear on the rope. A rough spot on the stock as has been mentioned adds to the wear. Chafing = broken filaments = reduced tensile strength. That rope started with X amount of individual filaments in it, break enough and it's seriously weakened. Just a thought... Sorry to hear of this happening, man.

the marks on your riser look (to me) to be cosmetic only..and I think youll just have to follow the same protocol as a dry fire on your limbs..
if they pass the cotton ball test and have no chips and such then twist that string up and shoot..

yes, that appears to be a good assumption. back in 1993 my exomag ( I think it was an exomag) had a problem, and I was told it would be ok to continue normal operation.
2nd time I cocked it... it cocked me on the right side of my head between the eye and ear....temple area !!! it put me to my knee's.
the right limb broke at the riser connection.

i'm gun-shy, and at my age...its not an adventure

but I do appreciate your input !!!! thanks strum

[Hunt it]

So that's why you wear the helmut good idea. The marks on riser are cosmetic you have nothing to worry about there. If the limbs have no slivers you should also be fine. Twist up string to get it away from reds and get shooting. If there is indeed a ridge or edge on rear of stock in rope groove get some wet and dry sandpaper and sand it till smooth.

My post above re rope cut was not a it's your fault comment. That rope could have gotten nicked anywhere from birth of rope to packaging process. Pretty hard to determine where,when,why or how as far as I'm concerned. Go kill something you'll forget all about this soon.
