Well it was warm today, so I chronographed the 3 nitrous setups that I said I would.
This is to see the difference between A base with standard 65% modules and the B base with either standard 65% modules or mini 65% modules.
Both bows have the same limbs 5M and with the same specs will provide within a half pound of each other. Also, both sets of limbs have the same limb tip deflection differential, so the tiller of both bows is very close to the same.
With the B base cams, all I did was change the modules, no other changes.
The arrow is 330.9 grains, 30.25", draw length is 30.5" AMO.
Bow A - 51.0# / 18.5# - 30.5"AMO - 63.7% LO - 8 3/16" BH.
- std 65% modules in last hole #4.0.
- 261 fps
Bow B - 50.5# / 17.5# - 30.5"AMO - 65.3% LO - 8 5/8" BH.
- std 65% modules in the second hole #1.5.
- 249 fps
Bow B - 51.0# / 17.5# - 30.5"AMO - 65.7% LO - 8 5/8" BH.
- mini modules 65% in the next to last hole #3.5.
- 255 fps
The B mini is the smoothest but the A std is the more crisp shooter. I like the A because of the slightly higher holding weight.
The difference in brace height accounts for at about 4 fps. This BH difference is built into the cams and at the same limb bend, the A base will always provide about a half inch lower BH.
