I have one xbow that shoots 400 gn about 375 fps and one that shoots same arrow about 390 fps. The faster one has never seen the woods. Just my backup. Speed ain't everything . Also I am hunting with 452 gn arrows so probably more like 358 fps.

I think heavier arrows are easier on the crossbow if nothing else.
I was recently watching some yt guy (death by bunjee),
he invited crossbow engineers to talk about crossbow limb failure,and from what i can gather crossbows are very inefficient (40 percent,compare this to longbows that are 66 percent efficient),what this means is on a crossbow only about 40 percent of the energy stored goes to the arrow,the rest disipates in the bow.
anyway,the more energy you can get the crossbow to use on the arrow,the less energy is left to go back to the bow.

I don’t know if you’ll understand or even if you want to understand. You are stuck on this aspect so much so it’s a detriment to your crossbow experience and you are spending way too much time overly concerned about it and going about it the wrong way.
So you have a KI bow, they had a lot of limbs that delaminated, they did not break,
Yes some broke but I truly don’t think that “light” arrows were the cause or are the cause. I’m pretty certain it was QC that was lacking and/or simply poor quality materials or finishing procedures. I think even with a small delaminating section on a limb you could safely continue to shoot it.

hey man,this isnt about me, the OP was debating on the pros and cons of heavier bolts,
I chimed in with this relevant link saying all things being equal heavier bolts are easier on your bow.

 

[Omondi]

interestingly if you watch the video, according to the crossbow engineer being interviewed ,the KE gain from using heavier bolts is negligible ,(5 percent)

 

[Tripplebeards]

I watched a couple of his videos as well. There isn't much gain or loss within average hunting arrow weights imo. I'm sure I'll just end up shooting my 407.5 grain carbon express KVs at 351 fps this upcoming season if I don't upgrade my xbow. My guess is the 30 fps I lost with new limb replacement will only drop another 2" or so at 60 yards. I don't shoot that far anyways. Normally just sight in at 25 yards and aim right behind the shoulder center mass out to 40 yards. I don't normally shoot past 40 yards. My average shot is usually 35 yards to 15 yards. Just riles me up to loose 30 fps and am trying to figure out how to get it back without buying a new xbow. Might have to try twisting my cables.

I’m wondering if you were supplied with 350 limbs. The bow is no longer in production and they may be running out of limbs. There were some limb issues with that bow. Still a damn fine bow.

 

[Tripplebeards]

Yeah, without a doubt they replaced it with The standard solution 350 ft./s limbs. Striker only made two solution models that I remember. The solution and solution SL390. The 390 had 155 pound lambs and were stamped 93. I don’t know what the standard solution limbs are stamped, but Bowtech told me mine were stamped 77 Which is a weaker which is a weaker strength limb. They also told me that the solutions with them specific and they were universal solution replacement limbs. I was also told that it was normal to slow down with the factory replacement limbs From Bowtech CS. So that tells me they were the 125 pound limbs that came on the solution. It does pull back a lot easier and smoother. I can tell you that so I know they were a lot weaker. Going from 155 pound limbs to 125 pound them slow down basically 30 ft./s. I’m sure the crossbow limbs will last a long long time now being that they are set up with less stress and less pull weight. I’m looking at buying a different crossbow right now leaning towards an R10 because I can de cock it after hunting and the limbs are super narrow for shooting out of my hunting shack windows. If I do I haven’t decided if I’m gonna sell the stryker off. Everything is basically been replaced on it except for the stock when it was in for service a few weeks ago. I still have five of the six arrows that it came with in only one’s been shot...and that was for testing in my chronograph last week.

Stryker 350 was my first crossbow. With a few tweaks, the Solution bows would be awesome still

The number on the limbs is how the manufacturer knows what deflection they are

Some manufactures ues the actual poundage as the deflection number and some don't

Barnesdale uses the actual number to the tenth of a pound.

Example 200.6 all high end scorpyd bows have barnesdale limbs. The deathstalker bows use limbs that have a 56 mark.

Bowtechs manufacture uses a number system that uses only whole numbers Like the Deathstalker

What this does is let them determine a range and then mark every limb in that range with a number.

Example a 77 could be any limb between 200.1 to 200.5 would be a 77. So one limb could be 200.1 the other could be 200.5

I don't know bowtechs variance requirements.

This system let's them pay less for the limbs because they waste fewer limbs using a variance system

I think scorpyd is the only company using barnesdale limbs so it's very likely the variance system is the industry standard.

Now on to arrow weight

In essence every crossbow is dryfiring everytime its shot. When manufactures began making compound bows their testing determined bows should not drop below 5 grains per pound of draw weight

Example 70# bow should never shoot below 350 grains of arrow weight.

So technically you would need to shoot a 1000 grain arrow on a 200 deflection bow to not be dryfiring it every time you shoot it

The industry knew this would never fly with consumers so they just accept the fact limb breakage is a part of crossbow sales
