I haven't had any problems with my Mag 340. I'm shooting 575gr arrows.

 

Hello, I saw you are shooting a 575g arrow from a micro. I have just bought my first micro and am curious if you had the arrows built, built them yourself and what components you are using.

Wyvern recommended his dragon claws. But, they only come in at 400g with a 100g broadhead. Even going heavier on the broadhead seems to limit my options.

Thanks for your time

No limb issues with my Assassin 360.

 

How many shots more or less? How long do you have the bow? I'm probably over 250shots already.

I really don't keep count,but can give you a honest round about of over 100.I shoot this more than my Scorpyds, and have been shooting a 431 grain arrow(total) Gives me an extra kick in the Speed dept,without going to light. I really don't worry about the limb's,as I can pick up a new pair,if needed with a Phone Call Unlike Scorpyd,that wont sell you diddley.

 

I've had my 360TD Micro for a year and no limb problems for me

 

Arrow weight?

No problems what so ever with my micro 335. But I shoot arrows over 425 + grains.
Easier on the bow.

 

Think you have nailed the secret to minimizing limb failure on a narrow bow - arrow weight. Obviously a manufacturing defect can cause any length limb to fail. With shorter limbs there is less limb area to store, transfer, and then absorb unused energy during the shot. Light weight arrows leave more of that unused energy. Arrows in the 430gr range or heavier will leave less waste energy for the smaller limb area to dissipate. Noise and vibration are forms of energy dissipation and both are reduced as narrow weight increases.

 

I keep a shot log. I've had my Assassin 400TD for 11 months, and shot a little over 800 shots with no limb troubles (knock-on-wood).
I have shot nothing but 450-500 grain arrows out of her.
I have had to replace her internal cocking rope once'
Replaced 1 R.E.D.S. string stop.
Replaced 2 XSHOX string stabilizer / silencers.
One complaint is the serving life, I'm only getting about 250 shots per serving. I have been reserving with Nylon but, I will be reserving with Angel Majesty 0.036 in the future. Yes, I lube my rail and yes, I have touched up all the "Usual suspects" Trigger jaws, arrow track, etc.
So far I still love the Assassin400TD.

 

Four limb issues with my Micro 355 . Ive bought it 2016 and had an issue every year. Usually i have used ~425grain. Sold it 2020.

Two times i have had tiny splinters at my Short 308.
If it "must be" a Micro, go with the Mag 340 ( newer limbs) and a heavy arrow (and a set of spare limbs).
And if you ask for issues, ask for the "arrow-output" too! An owner of a five years old bow with ~300 arrows on it is no reference for me.

Sorry for your bad luck. Heavier arrow did not work for you. You had the gen 1 rizer? I've got the 340TD and suspect Excalibur changed something. They changed the rizer limb pockets.

So far 7 guys have had no limb issues and only one had limb problems but it was pre-2016 Micro. It is beginning to look like the limb problems were much more on pre2016 bows.

I hope so… I have a mag 340 (new this past winter) less than 100 shots on it and am following along looking for reassurance. Lol.

 

Shoot heavier arrows than 400gr and I'm sure the Mag will kill for many seasons. Very good bow.

I honestly believe a longer "working" limb has more area to dissipate excess energy ( in the case of shooting lighter arrows) The shorter stouter limbs don't flex as much and so the energy has more time to damage the limb?

 

Agree. My old Exocet 200 is still going strong. I've changed the limbs because the camo finish started coming off due to old age. Still have the old limbs and it's in 100% working order.

Maybe the question I must ask is, who has got a new post-2019 Micro with limb problems? And that can honestly say they never shot a 350gr arrow out of it.

Yes there have been, but you'll have to wait for the results to trickle in on an individual basis. When the Axe 340 first came out there were a few on this forum that had limb splinters, you can go back and find them for yourself. The Axe/Mag 340 has been a huge success and seller for Excal though, so the ones with failed limbs seem to be an incredibly low %-age. I picked up an Axe 340 for my uncle that was on its 2nd set of limbs. And the Micro 360TD had quite a few reports of folded limbs And I have seen a few 400TD's with the High Output Express Limbs on here and fb groups with folded limbs. But very few. All 3 of those models are post 2019.

Just what I have seen. We have quite a few micros in the family now, have backup limbs on-hand, but have yet to need to use any of the backup limbs.

 

There are so many posts on the Micro series and limb failure. Is there anyone besides me that had only had good results with the Micro series so far? I don't know if Excalibur fixed the limbs, or is it the limb pockets on the new Micros that's helping, or maybe the fact that I shoot arrows that weigh more than 400gr. Use a flemish string? but I've had zero issues, except the mounting bolts coming loose once and no problem after applying the blue Loctite. I just love this narrow crossbow.

Every Trad guy/gal has known (forever?) a Flemish string allows less stress on limbs of the bow. This is beyond dispute, as there have been books (parts of / the bowyers bible series) written over the subject. The fractional loss of speed for the Flemish is more than made up for by the integrity gains of both the string and the limbs that it is attached to, in reference to the recurve. While only guru's (by todays standards) know this fact, it is none the less a fact.
So this is the added benefit that you are gaining over the endless loop, as you have modified your bow.

Every Guru also knows that the AMO standard is the gold standard for any recurve, of any design.
The crossbow is no different than the longbow. Limbs are limbs.
When looking at the Micro series bows, we are looking at 2.5 to 2.0 dependent on draw length, to meet the adjusted AMO standard.
By adjusting upward of the factory arrow weight (ridiculous and only there to make FPS ratings) you agian have added life to your limbs.
This is why (IMO) you have had a better experience, maybe.
Also, we must look at shots fired, as even a dry fired bow can last a good length of time.
Lifetime? ... Not going to happen at 1.5 or lower unless you shoot very little.

I have the micro 400 TD have around 150-200 shots and zero issues. Shooting a 425 grain arrow.

 

Hope you have many many more.
I shot that many times a day. As I said...
If you shoot very little, even dry fire condition can make it.

 

I had a sliver on a 405 and that’s all. I’ve owned countless Excals so that’s very bullet proof to me

 

I bought an Axe when they first came out. After a couple hundred shots with 400grn arrows and factory string I had a limb sliver. After warranty replacement and hundreds of shots I haven't had another problem. I bought a second one and it's been trouble free to date. I use Flemish strings and 400grn Dragon Claws from Wyvern Creations. Never shot a 350grn arrow from either of these bows. Even though I've had pretty good luck with limbs I always keep a backup set in my case.
Take care

The way I see it is that Excalibur needs to see, the people that buy an Excalibur recurve crossbow aren't looking for speed. Simplicity, durablilaty, and accuracy are higher on our list. They need to change the arrows that come with the bow and increase the min weight to at least 400gr. This will drastically reduce the limb issues and will restore the bulletproof name that came with Excalibur crossbows. We don't care for 400fps second ratings on a recurve crossbow. The Micro 340 that I'm using is getting full penetration on all animals I've shot so far, and that is with a 425gr arrow at 305fps. The buldog 440 will be a 390 the 340s will be 310 and so on using a min arrow of 400gr.

I bought a Micro 335 the first year they came out. I've shot many animals with it. No issues whatsoever. My arrow weight is 410 gr zombie slayers. Love my 335!

There were/ are 2 kinds of limb failures. The issue of slowly folding in slow motion is gone by getting rid of their camo vendor and a limb geometry redesign. Splinters can be reduced by heavier arrows but so can the elimination of semi dry-fires which is far more common than most can admit. Semi dry-fires are extremely common and difficult to recognize. Semi dry-fires and light arrows have a whole lot in common as to how they effect the limbs.

 

Boo,
What are you calling semi dry-fires? Is it when someone doesn't have the arrow all the way against the string or when they forget to put an arrow in and it hits the anti dry-fire string catch?

 

2019 Assassin 360 had 2 of them broke 3 sets of limbs with 450-500 grain arrows. Loved the bow, but got to know Peter at Excalibur better then my own brother. They always took good care of me, I am sure folks at customs know my name and address by heart. I loved the simplicity of the bow, I loved the easy of grace adjustments, re stringing it, etc. I sold both bows to 2 different friends after Excalibur send me entirely new head units with limbs. They are still shooting them today not one single hiccup. There was something with the preload of these heads, machining, etc. causing the breaks, they are not splinters they were internal delaminating where limbs would fold back. I missed a nice deer because once broke on a shot sending arrow way off course. I just lost confidence and haven’t went back to Excalibur. I am seriously thinking about a 400 TD I loved the blue trigger on my 360 and the cocking and de cocking with the adjustable stock. Heck I liked the tact zone scope. I never shot the super light weight quill tooth picks that came with them. I would love to try another but I am a bit gun shy.

 

You might as well be addressing a Rage fan. LOL
Like anything that is marketed to raise the esteem of the user, the user will fight to the death, their absolute superiority for having the good sense to follow the other lemmings off the cliff.

Seems like not having ones DNA modified by some unstudied injection might not be the mistake some believe it to be.

If arrow seating and or flat nocks are the problem , why not fix that issue rather than to keep shipping out new limbs? Seems like the engineers at Excalibur could come up with a pretty simple answer for that.

 

Thats not the problem. It could be a problem and likely happens but it's not the problem.
The biggest problem is (IMO) that the AMO standards have been abandoned. Every older Excal followed that standard and had basically zip for issues related to limb breakages/delaminations.
It wasn't till the G.P.P. standard was dropped (by introducing 100# added weight) that things started happening. Of course, there were also the issues aside from that which were built into the destruction process but all the same, as those things were addressed (and breakages dropped in percentage terms) breakages continued.

Some people will claim that the G.P.P. standard doesnt apply to crossbows (never have heard that one explained) but the vast majority who have followed the adjusted A.M.O. standard, report breakages ceased to occur after doing so.
This isn't rocket science to any bowyer I have ever met or known but it sure is a head scratcher for those who simply buy parts and assemble them.

With the responses I see, I'll take the high road. Life is way too short. Have a nice day everyone!

 

Who took the first poke?
Dont act like you were just walking down the road and were suddenly assaulted! LOL
Pretty sure you are the one who threw the first punch
Besides...
We all have our opinions and that should be irrelevant to the discussion.
Just ignore the responses to your jabs, move on and leave the snide remarks in your head.
All will be well and we will all be better off for it.

 

Boo I guess that's why My Micro 355 is still going strong 3 years later. I constantly check my arrows are seated against the string. Well that and I have from day one shot 400+ gr arrows. I have told this story before but I literally backed over my 355 with a F150. I was distracted by a phone call while changing out of my camo. I lean the Bow against the back tire and except for this one time I put away my camo then put my bow in the truck. I got in my truck threw it in reverse and backed up. I felt my front tire roll over something and I thought there wasn't anything there when I pulled in. As I backed up I look over and instantly new what it was. It was one of those OH CRAP moments. I got out expecting to find a mangled mess but to my surprise the only thing broken was the Quiver, Quiver mount and 3 Spynal Tapp arrows. When I got home I put one of the un-broken Tapps in the bow and it was dead on. Before that moment I always thought the destruction challenge was fake but not any more. Either way I shoot the crap out of my little micro and she sends a arrow exactly where I am aiming every time can't ask for more then that.

 

The Rhino nock set up one would assume will eventually make it to the entire line up. Once those babies are locked in the hold tight. Excalibur is not the company to experience partial dry fires. Any nock that isn't a snap on is subject to this
