As to your 5000 shot bow...
You actually counted those shots huh? Really?

I'll accept that you threw a number out there and the fact that you shot it a lot. Hows that?
Thats a Matrix, correct? Yeah.... That limb size eats up a lot of returned energy, like a shock absorber. Like longbows, the longer the ATA the longer they last. I have a 380 myself. Bullet proof they say. That said... I have seen/heard of them giving up the ghost to factory loads. Never heard of it with heavy arrow though. I wonder why that would be?
Well we can agree on this. That said.... You grossly over represented the AMO standard, as you did not convert it to relate to the crossbows in question.
As a matter of fact NO!I quit keeping track at around 3000 when I realized how many times I didn't record my shots,,, that was over 3 years ago!
I will say in that Time I've owned 3 Parker's a Cyclone and 2 Gale Force, great bows. no less than 3 Scorpyds I think 4 but lost count, one extensively customized with three sets of limbs. 3 Tenpoints, probably the best compounds I've owned, a Native, a Dalton, one Mission, but since it was introduced the Mad Max and it's Mad Maxine barrel have never left, and are still shot almost daily mostly in the Max configuration. But absoluetly well over the stated 5000 shot count!
Please understand, that I also owned well over a dozen different Excaliburs in them six years and shot everything from 350 grains to over 520 grains in some. The only one ever to have a failed limb was a Micro 335 nightmare I had bought used, and have no idea what was shot in it before I got it. But I always shot 415 grain and heavier. The limbs broke early and after being replaced and converted to a predator 3D deception camo'd bow I shot it a lot and never had an issue, and believe the man who bought it has had the same luck.
Now after my resume, I have for over 8 years on these forums claimed less than 400 grain is not only ridiculous, but not near as efficient as 425 and above in any bow from 315 fps on up. I usually shoot 425 to 480 grains, but do use 529 grains in thicker coverage like swamps and thickets I hunt in, on the ground.
But one thing I never do is single out any one company as having trouble because the use to light a limbs to get their rated speed. I don't do that because most realize you had have to single out every one of them,, they all do it. That's because "Speed Sell's", Sadly few understand much else when considering which bow they buy!
As for breaking limbs,,, I have had my best luck with Parker! and only Scorpyd and Excalibur have ever failed me, and the Excaliber had a few test shots with their 355 grain bolt just to see if it would meets its rated speed, as I do with every Excalibur I have owned, as well as Tenpoint and their 370 grain claims, but they do rate for 400 and 425 as well, and some over 445 in their advertising.
But that scorpyd never seen less than 425 grains, and it failed sooner that any. But that was one bow and one set of limbs, they were re[laced and never another problem. I test continually, build my own test patterns, change my bows like a little girl with a doll and clothing sets. But trust me I build and test 100's of sets of arrows, and not just for bags, I build and test plenty of different configurations for hunting, and test them in all weights, always with fixed blades, but please, don't insinuate that I would inflate numbers!! As I will assure you my numbers will never be over inflated,, or my coments!!
These are just a few, mostly Executioners, and no Zombies or Tapps, My main go to arrows!
So My question to you is, how many have you experimented with, and how in depth have your arrow assortments for these test that verify your remarks have you went through???? Again, fan boys usually have no experience with most of the thoughts they have and show their authority on what they read,,, hope your not one of those??
