Ill post here the formula for calculating free recoil of your gun in a certain caliber. It will give you a number which may not mean too much, unless you compare it it other calibers you have shot. For example your free recoil of a .30-06 may be on the order of say 15 ft/lbs and a .450 Marlin using handloads designed for the Encore and you will get say 45 ft/lbs. Now, if you have shot a .30-06 Encore you can guess the recoil will be 3 times greater.
Here is the formula:
(W1xV+4700xW2)^2
__________________
(64.348xW3)
W1= Weight of bullet in pounds
W2= Weight of powder charge in Pounds
W3= Weight of gun in pounds
V= Velocity of round
(to convert grains to pounds divide by 7000)
So for an example:
.257 Weatherby Magnum, Nosler 115 SP, 86gr of AA 8700 for a vel of 3330 fps.
so: W1= (115/7000)=0.01643
W2= (86/7000)=0.01229
W3= 6.8 (this is what I use as a general weight for a wood stocked standard barrel Encore.)
V= 3330 fps.
*EDIT*
now: .01643x3330=54.7119 & 4700x.01229=57.763
Thus (54.7119+57.763)^2=12650.1
12650.1/(64.348x6.8 )= 28.9, But to compare to the .17 Rem?
.17 Rem, Hornady 25 gr HP, 27 grains of AA 2700 @ 4083 fps.
instead of redoing all the math mumbo jumbo Ill just give you the answer: 2.49
So the .257 Weatherby will be quite a bit more recoil, but will be nowheres what the 209x50 will be. The 209x50 you can pretty much bet on shotgun type recoil (Id do the math, but its early and my head still hurts from all this previous math :lol: )
I hope this lets you get some Idea of what your dealing with.

*EDIT* So you can see I was wrong in the actual recoil. It is a fair bit higher. Im still betting it will be lway ess than the 209x50. Now this does not reflect on percieved recoil. Things can change how recoil is felt like muzzel breaks and different recoil pads. The same formula can be used for handguns too, but their precived recoil is different because more of the energy is transferred upwards as the barrel goes up in recoil. I again add my apologies for screwing up the math :oops: .
