Cam Device Name?
I know this probably isn’t the best sub for this but I didn’t know where else to post it. Can anyone tell me what this style of camming device is called?

Just recently picked up a clock bag from house of Staunton. It’s fairly snug but I don’t have to jam in into the bag or anything. However when the bag is closed it does somewhat depress the buttons. Not all the way but definitely some. Is there any issue with storing it like this? I wouldn’t think so but I also don’t want to go messing up a nice clock.
Had a little bit of a surprising situation happen and I was curious as to see others opinions as to what’s going on.
Shooting a 40#, Gillo GQ with Delta C3 Long Limbs, 70” overall length.
I had previously been shoot 30” 600s with a 100gr tip but recently realized that I probably need to move to 500s. Switched to shooting 30” 500s also with 100gr tips (though I may move to 125s).
The surprisingly thing is that even though the 500s are ~30gr heavier they are actually impacting higher at all distances (string walking). Not what I would have expected considering they are heavier. They are also all fletched the same. Left helical with 2 deg offset.
Only thing I can think of is that now the spine is better matched so less of the energy is being “soaked” up by the weaker spine arrow. That being said it’s only a guess. Thoughts?
Pic for attention. Marvel at my ability to blow an arrow into 4 pieces (couldn’t find the last inch or nock). First time I’ve managed that.
