Encore Recoil
« on: December 23, 2003, 05:16:38 PM »
I was wondering how the felt recoil is with large calibers on the Encore carbine frame. I have a .17 Rem and a 209x50 (I have only shot the .17 so far). I was interested in getting a .257 Weatherby Mag barrel made.
Any input is appreciated.
Thanks

As posted elsewhere, my new-to-me .300 Winchester certainly has some recoil, but it's not noticeably worse than other medium caliber centerfire rifles. The .257 Weatherby should recoil less, but may be louder!

On my very limited experience, it seems the recoil from the Encore is comparable to or less than a similar caliber in a bolt action rifle.

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: .

YOU ARE MY HERO!!!!!!!!!!!  I am a math idiot and you are the King!!!!!
Thanks for that info-It was very informative and interesting.
I was just worried about the recoil being the Encore is so light.
Thanks again-
I'm not worthy..................... :)

My pleasure.  I had been worried about weight too.  But for the average number of calibers, the Encore compares pretty well to many ultra lightweight/compact hunting rifles that seem to be the rage.  The bigger calibers can thump with a light gun, especially compared to their counterpart gun, as most in those class have a few extra pounds of weight tacked on.  Ive been doing the math, and I figure by adding a 3lb stock weight (that are available in Brownells to slip into the buttstock of competition ARs) into a wooden stcok will bring the recoil of a .300 Win Mag down to about the .30-06 recoil range  :shock: !  This means that one can practice shooting the Win Mag with only a medium shove, then switch back to the lighter stock for hunting (if needed.)  I know this does not really apply to your situation, but it is a good example.  Heck, you could even make a .257 Weatherby recoil close to the .17 Rem by adding enough weight.  Ok, now my head is really begining to hurt  :) .

:oops:   :oops:  :oops:

Encore Im taking my crown off for a second as I am embarassed.  It seems I had a flaw in my math.  Usually I do my calculations on my scientific calculator, but this time I used the basic calculator on the computer and I forgot math rule #1......do all multiplication BEFORE adding.  So the actualy recoil will be higher.  It will now be in the .30-06 class (what I call medium recoil) range.  Im going to re-edit my above post, so you can see the changes up there.  The ratio should still be the same, meaning the difference between the recoil of the .17 Rem compared to the .257.
So SEE ABOVE FOR EDIT
Again, sorry and happy holidays.
