I am selling a Stevens Model 47 Action. It is a single trigger action. It has an incorrect trigger spring and it is missing the hammer spring but other than that the action is in great condition. I am selling the action for $650 plus shipping.

It is a centerfire. It does have a 7 O'clock extractor.

It is lugged

Is this 47 a 44 or 44 1/2 action? I still learning about single shots so please be patient with me.

I have a decent original 7 o'clock Stevens barrel in 32-40, with an excellent bore I'd sell to the person who buys this action, if they're interested. It most likely would need to be fitted, as it won't likely index.

Very nice looking Stevens 44 action and that should make a nice rifle.  Nice that it is  alugged action.

Without the hammer lug, up to .32-20.  Not .25-20 WCF if there's any chance that factory ammo might get into it.  .44-40 and .38-40 with blackpowder pressures.  .38 Special low pressure target loads only.   .32 S&W long good, not .32 Magnum.  All 3 of the Stevens .25 caliber centerfires.  .28-30-120, .32 Ideal 

With the lug, .32-40 target loads, not smokeless hunting loads.    Maybe .22 Hornet.  .38 Special but still not +P.

The lugged hammer was supplied only for .32-40 and .38-55 chamberings, so this action was one or the other when new.  Rational smokeless loads for plain base cast bullets will be fine.

Yes.  Recent .38-55 pressure test gave about 12,500 psi with modern black powder.  The real limitation is not pressure but breech thrust.  Pressure x internal base area.  12.5kpsi gives about 1550 pounds force (lbf) which the lugged hammer action can handle. 

The weak point in the 44 action is the link in the toggle mechanism.  The geometry subjects it to about 70% of the direct breech thrust, which an awful lot for those tiny pins and a link which is just mild steel, case hardened.  The battering causes the holes to open up, and the lockup (not to mention headspace) goes to pot.  The lug on the hammer is there to transfer that force to the hammer axle, which is a little more able to take the load.  Without the lug, about 1000 lbf. is the limit, if you want a reasonable service life from the action.  More won't blow anything up, it just loosens up the linkage, and the looser it gets, the faster it gets loose.

uscra112, You have provided very knowledgable comments.   

In the late 1970s or early 80s, there was a gunsmith that was producing heavier duty/stronger link pins.  I beliebe they were slightly larger diameter and high strength steel and not a 2 piece pin.   

At that time, I had a Stevens 44 and thought about sending it to him to upgrade.  However, I traded that rifle before sending.
