Don't know why it reads like some one is upset, if not my bag.
There are formulas for free recoil. I have a couple but i am to lazy to type it out.
Here are trhe numbers I ran with my loads and a good guess. Of course powder charge wt will be a variable. I am not checking ME but PF (130).
115gr @1130 w/5gr of powder = 4.98 FR
124gr @1040 w/5.5 gr of powder = 5.07 FR
147gr @ 884 w/ 3.2 gr of powder = 4.44 FR
My 124 gr loads @ 1180 w/ 6.2 gr of powder = 6.51 FR
Again the powder charge wt has an affect on the FR.
Doubt FR is the symbol for free recoil, but this is my work.
I don't know how to use a calculator, but can use excel for the simple stuff.
Just go and pull up the formula for free recoil and do the numbers yourself in the same wt of the firearm.
Then we go back to personnel preference.
Of course the free recoil formula does not take into account things like backstraps, bbl length, bore axis, or even sharp edges. It assumes all variables are the same with the exception of powder ch, bullet wt, and vel.
Again the powder itself can give a different feel to the recoil impulse as can ., well just re-read my first post.
Hope you figure it out it cause it sure aint rocket science
