Spitpatch --  I would/could only suggest you have a hand made tang of necessary length/width X 1/8" thick 4140 steel welded to the rear of the action. This would require inletting into the stock wrist and a bit of shaping the radius to match the rad. of the tang sight base for a good fit. Of course, this would also require drilling and taping for base and the action be reblued. FWIW,   Ken

Spitpatch,
The method that Ken suggests is a very good one and is the way Browning put tangs on the first 1885's.
However there is another way to skin this cat.
Take a piece of brass 3/8" wide and 3/16" thick and 2-1/2" long and inlet it into the wrist of the stock. It should stand a little proud of the wood so you can file it flush. It should then be drilled and tapped for the sight mounting screws and be epoxied into the wood. This will give a solid, metal base for the sight. There may be some slight movement of the sight from summer to winter as the wood expands and contracts with moisture but if the stock bolt is kept tight this should be minimal.
When the next issue of the Journal comes out my series on the "Modest Schuetzen" will pick up again and I'll be covering installing a tang like this on the H&R.

Spitpatch,

There is one more way.  I'm shooting a rebarreled B78 in BPCR silhouette competition right now.  I attached my MVA tang sights by drilling/tapping a 10x32 hole in the rear of the action, right behind the cartridge deflector, for the front screw.  The rear of the tang is fastened with a brass insert that is threaded 10x32 machine threads on the inside, and wood screw threads on the outside.  This insert is screwed into a pre-drilled hole in the stock wrist.  You can usually find these inserts at larger hardware stores (but might have to re-drill/tap to get the size you want)

I haven't had any problems with mine so far (going on 2 years of twice-monthly matches), but will have a tang welded on as soon as I can con my favorite metalsmith into the job.

Even if you get the sights a little off you can shim them to plum.  Put your rifle in a vice an level it. Both front to back and side to side. If you have a a sprit level in your front sight level it, Once you are true then put a level along the side of your rear sight(vertical).  If you are off shim till it becomes plum  with the bore. If you dont  have a  spirit level in your front sight and  you have a octagnal barrel you can lay your level  across it and adjust you rifle in the vice to get it level.  You can also put you level across the action and level this way also. Once you determin the shims needed  cut them to fit under the sight out of sight and you are there.  You should plum in your sight front to back also.  Most sights have an adjustment for the  vertical notch(front to back)  and this needs to be adjusted  and plumed in as well.

Hope that helps.
