The Kid Posted November 15, 2007 Report Share Posted November 15, 2007 hey guy i just wondered if anyone new if you could order other limbs from the mathews dealership so i could pull more lbs back. i was thinking on maybe trying to pull 80 to 85 lbs. i just didn't know if mathews has other limbs that you could order. thans for all the help.

Guest bigalt78 Posted November 15, 2007 Report Share Posted November 15, 2007 I shoot a pse firestorm x and i have the 70 pound version and i maxed it out all the way and i got 84 pounds out of it. if you're shooting 70 pounds right now its probably actually 75. when they say 70 usually most of the time its really 75. but i dont think mathews makes 80 pound versions in most of there bows.

Huntin4ever Posted November 15, 2007 Report Share Posted November 15, 2007 I have a PSE Mach 7 and I got the 70-80 lb limbs put on it a few years ago..... I target shot and hunted one year at 82# and the difference for me was just under 10 fps..... I decided it wasn't worth it and now have it set at 69# which is about as low as I can go with it now with the heavier limbs..... my theory behind backin it down was that, yeah when warm and practicing, etc it wasn't that big of a deal to pull, but go sit in 20 degree weather for a few hours not moving and it gets a lot harder..... anyways yes you can get heavier limbs.....

Southerngirl Posted November 15, 2007 Report Share Posted November 15, 2007 I'm sure you can, but why would you want too? Quote Link to comment Share on other sites More sharing options...
The Kid Posted November 15, 2007 Author Report Share Posted November 15, 2007 i want my arrow to hit harder so should i just get a heavy arrow? Quote Link to comment Share on other sites More sharing options...
Southerngirl Posted November 15, 2007 Report Share Posted November 15, 2007 My only concern is the more pounds you pull the higher the chance of you injuring your shoulder. If you are pulling 70+ pounds you shouldn't need anymore knockdown power Quote Link to comment Share on other sites More sharing options...
Huntin4ever Posted November 16, 2007 Report Share Posted November 16, 2007 If you are wanting the arrow to hit harder it is a matter of physics..... what you are talking about is the kinetic energy of the arrow.... which is 1/2*mass*velocity..... so let's say that by going to a heavier draw weight for example you go from 265 to 275 fps with a 400 grain arrow (shaft, knock, fletchings, and broadhead) then you are increasing the kinetic energy of the arrow by 3.77 %..... however, if you were to go from a 400 grain arrow setup to a 425 grain arrow setup (switch from 100 grain broadhead to a 125 grain broadhead) and stay at 265 fps then the kinetic energy of the arrow increases by 6.25 %......... So what all that means is that if you're wanting your arrow to "hit harder" (better penetration) then go with a heavier arrow setup and keep your bow at the same "weight" (really velocity, fps)..... hope this helps....
