Hornet Barrel on Pardner?
« on: December 05, 2006, 04:15:13 PM »
I got a .22 Hornet barrel today that fits my 20 gauge Pardner bug out gun perfectly.  I know you aren't supposed to put rifle barrels on the SB1 frame but I think I'm gonna try a few shots.  I can't see the Hornet being too much for it.

be sure to let use know how it works out. It would be a nice package as a 20 gauge "bug out gun" with the .22 Hornet barrel in or lashed to the pack and some extra ammo in the pack....<><.... :)

I would think the back thrust of the Hornet would be very minimal.

The back thrust of the Hornet at 41k is 2011lbs asuming the the inside diameter of the case is  .250 at the the pressure ring.

The hinge pin in double shear is about 13246 lbs  asuming a tensile strength of  80 kpsi.

Whether the frame (cast iron) can stand the stress is the question. Frame section = .656sq/in. Cast iron ultimate tensile strength is 18ksi. Asume 1/2 that as static safe loading and 1/2 that as impact loading. Total safe load 2952lbs. Loads could easy exceed this this safe load using higher pressure loads.

The frame under some unknown coditions is not safe to use from what I can tell.
This is why H&R does not recommend the use of  SB1 frames for rifle loads.

Besides I dont know the strenght of the cast alloy used by H&R. I could easy be less since it is only used for shotguns which operate a 12Kpsi.

Final note cast iron does not stretch like steel. It simply breaks. Don't be a hero.
Besides if you do unsafe stunts, don't broadcast them to the public.

So far at least a dozen filks have stated they have been doing it for sometime.  H&R did it for quite some time.  The worst that can happen is the reciever will shoot loose.  It's not going to come apart.  I believe the back thrust of a 12 gauge 3 1/2" turkey load is greater than that of a factory loaded .22 Hornet.  If I die, I'll let everyone know.

Dropped off my frames to my buddy tonight.

SB2
SB1

H&R Buck frame.

Hopefully will have the results of the Rockwell test tomorrow.

I don't know about the strength like Fred has shown, but it doesn't really bother me too much.  I use the criteria H&R has used since the very early 1950s on their various Topper models.  The .22 Jet, .22 Hornet, .30-30, .357 Mag and .45-70 have been used on their cast iron frame (maybe the .44 Mag too?).  The Hornet used to be a 47,000 cup loading and as such, was the highest pressure round out of the bunch.

I have a .357 Mag barrel on an H&R "AU" frame and a .45-70 on another SB1 frame.

It isn't a recommendation, it's just what I choose to do.   ;)

The Rockwell hardness test is performed only on heat treated steel. Never heard of being used on cast iron. As a matter of fact how do you heat treat cast iron. I think if you quenched red hot cast iron it would crack. Besides hardness would tell you nothing, cast iron is quite hard but has very low tensile strength and used only in low stress applications.

It is your choice of doing what you do. My self I have never designed and overloaded  any structural component.  I my line of work it was and still is against the law to knowingly do so.

Sorry you guys that I stuck my nose into that one.

Here's the thread I have been looking for and finally found it, after a lot of searching:

http://www.graybeardoutdoors.com/smf/index.php?topic=94528.msg1098249434#msg1098249434

The larger firing pin is my main concern here with these cartridges. There are many chamberings that were offered that seemed to hold up in the older/weaker receiver, that they advise not to shoot in the SB-1's today.
I have done it...but I won't advise it.

Fred,

That wasn't an attack on you.  I was just saying I don't know about the strength of metals.  ;)
