can any one tell me what would be the tightest gap of these two set ups..keep in mind both bows are shooting 285fps....if i use cxl 250s 85 grain tip,2.3 vanes for a protec..then if i use 2312 with a 70 grain tip 2.3 vanes with my ultatec.both bows are shooting 285 the protec is about 4.5 grains per pound..ultratec is about 5.5 grains per pound..both bows are 28 inch draw....any info would be great i have tried this my self and did nothing but confuse my self with what i should shoot..really both bows shoots very well with there set ups..pluS both bows have the cam&half 75 %let off..

Speed alone does not indicate what your pin gap will be. A FAR more important measurement is the sightline distance, or the measurement from your peep or eye to your sight pin. This distance has more effect on your pin gap than changing speed.

Here's an exampleusing a common cabon arrow and 3" vanes on both)
Arrow speed: 280 f/s Peep to pin measurement 30"
The gap from 20-50 yards is 13.14mm (.52 inches)

Arrow speed: 270 f/s Peep to pin measurement 28"
The Gap from 20-50 yards is ALSO 13.14mm!

Now lets keep the speed the same and only change sight length:
280 f/s 30 inch sight length
Gap from 20-50 yards 13.14mm

280 f/s 28 inch sight length
Gap from 20-50 yards 12.33mm

To make a long story short............
If you want close pin gap, shorten your sightline distance!

Happy Shooting!
