This is not a questions about fobs vs blazers, or Xpedition vs XXXXX. I am only concerned with the numbers.
I am trying to decide whether the current setup I have is worth keeping and always wondering if I have an bow that is capable of ethically killing game or if I should trade for a faster setup.
I have a 2015 Xpedition Perfexion in a 28.5" DL, 60 lbs, D loop, peep, shooting a 400 spine Kinetic Kaos arrow with 100 grain heads with Fobs weighing 431.7 grains, OR with 2" blazers weighting 425.1. The average speed of this setup is 257 with fobs and 259 with blazers.
Doing the math the following is what I find true:
KE= 63.2 foot pounds
Momentum= .492 slugs
FPS= 257
Grains= 431
KE= 63.78 foot pounds
Momentum= .491 slugs
FPS= 259
Grains= 425
Since I have a 28.5 Dl the cams on the perfexion are the smaller ones, and the IBO is 325 ish. I understand this is IBO and not what my set up should be close to but for information purposes I state the facts.
I am not a fanboy and I am not stuck with Xpedition but they manufacture another bow with a shorter ATA and Brace height called the Xcentric 6. Again this is not a just get a brand XXX bow.
The IBO for the Xcentric 6 is 354. The X6 only comes with one type of cam.
Given my set up is approximately 68 FPS lower due to my DL, draw weight, and arrow selection. I present the following scenario and question...
If I were to get the Xcentric 6 and use the same arrows and take off the 68 from the 354 leaving me shooting the same arrow at 286 fps the following is what I calculate...
KE= 78.27 foot pounds
Momentum= .547 slugs
FPS= 286
Grains 431
KE= 78.26 foot pounds
Momentum= .543 slugs
FPS= 288
Grains 425
If the shorter ATA and Brace height lends to a less forgiving bow, is it worth it to switch for the greater KE and momentum?
I don't feel comfortable shooting an animal at 60-70 yards not because of my ability but because of the energy the arrow has at this distance. With the faster bow the numbers don't lie, the arrow has more energy, momentum, more penetration.
Should I trade my setup for a new set up, or is my current setup an ethical rig to kill at these longer distances?
