Black Mag3 is still difficult to find in stores. I ordered mine from Midsouth Shooters Supply. I also have heard that Cabelas has it too. Problem is that they charge a $20 hazmat fee so you need to get with someone and order a lot at once. I only ordered four pounds and now I wish I had ordered a lot more as I love the stuff. It works pretty much like their web site says. I killed an elk with 80gr. behind a 295 Powerbelt shot completely through rib cage but did not hit heavy bone.

I don’t know of a way to calculate a muzzleloader’s recoil, but I’m sure somewhere on the internet there’s a gun honk that’ll tell you all about recoil. Might want to check out Chuck Hawks website, there’s a ton of general gun and hunting info. there.

I shoot 80 grains of T7 under a 260 grain Nosler-Partition HG and the felt recoil for me is on par with 12 gauge shooting a 2 ¾ inch 1 oz. slug. I bought a slip on Sims pad and the felt recoil dropped dramatically.

I also shoot 90 grains of FF black-powder under a .50 177 grain round-ball out of Lymans GPR. The felt recoil of that combination is a lot less than the Omega. And the GPR has curved steel butt plate that will give you a nice bruise if you don’t have the gun shouldered properly. The GPR is a pleasure to shoot compared to the non-Sims Omega.

The computation for a blackpowder gun is the same as for any other gun. The difference lies within the fact that 100 grains of blackpowder is measured by volume, not weight like smokeless powder. So if you want to compute your MLs recoil then youll have to weigh a 100gr volume charge (or whatever you shoot) and you will also need to know the velocity of the bullet. Also, if shooting a saboted bullet, be sure to weigh the sabot too. Everything that leads the barrel is considered to be ejecta and is used in the computation. There is a calculator on beartooth bullet's website.

A quick analogy:
My 30.06 kicks like having a buddy punch you with a closed fist. My ML is like the same buddy pushing you with an open fist with half strength. Not the most technical definition, but clear to me on the difference.

id have to say its what you load with.....i can shoot 90grs of 2fg goex and a patch and ball out of my tc 50 cal hawken flinter all day long....but i loaded it with 100gr of 2fg and a 350gr maxi hunter....and it hits me pretty good...actually hurt pretty good a few time.....when i was kinda prone.....leaning over a hay bail.....if it had a scope id have scope eye...the way it comes back and up....but i agree it is a slower recoil....kind of like a hard push..and my gun is a traditional one and its rather heavy....but you load it up with a heavy bullet and a heavy powder load it will let you feel it.......never shot an inline or sabots........

I found a website that has a "recoil calculator". Most info that you need to plug in can be easily obtained from ballistics charts, etc.
