Outdoor Life magizine

[sniper model 12]

If ya get the chance, Outdoor Life mag in the October issue, has a cool chart and formula to calculate recoil.

First you must calculate the backward velocity of the gun:
[(1.75 x Wp) + Wb] x Vb
____________________ = Vg
7,000 x Wg


Wp= Weight of powder charge in grains
Wb= Weight of bullet in grains
Vb= Velocity of the bullet in fps
Wg= Weight of the gun in lbs.

Then you calculate the Recoil Energy:
Wg x (Vg)squared
_______________
64.4

The Recoil Energy is measured in ft-lbs

My rifle kicks out some nasty recoil around 2.3 ft-lbs

My specs:
Wp=24.5 grains (estimated maybe a little too light)
Wb=40 grain Vmax
Vb=3900 fps (Hornady specs)
Wg=14.4 lbs

Actual specs without the additional gun weight (factory weight with scope):
Wp=28 grains
Wb=40 grain Vmax
Vb=3760 (chronographed at 50 yds)
Wg=9 lbs (with scope)

This gives me 4 ft-lbs of recoil.

I just found a bunch of online calculators to determine this too. This one looks to be pretty good: http://10xshooters.com/calculators/Rifl ... ulator.htm

You can try searching google for "recoil calculator" also.
