Remington Hepburn Match B

Hello from across the pond. It really amazes me what surfaces out here in Oz....expect the unexpected!
I recently located a Hepburn Match B Hi-Power rifle in .30/40 Krag that's been here since the 1920-30's. It has all the bells & whistles including sling eyes and a 34" barrel. The only things missing were the sights. A late production rifle with serial number 90XX.
I ran this rifle past Tom Rowe and he came back saying that it was extremely rare to find a Match B in .30/40 with such a long barrel. Also the keen sighted among you Hepburn fans will notice an extra screw in the action (LH side, just above the hammer screw). This looks like it was installed at the factory and is a grub screw with a concave  dimple on the end. I have no idea what it's purpose was and nor did Tom. I thought it might impact on the hammer (why?) but there is no corresponding wear marks on the left side of the hammer. Any suggestions as to its role?
It's a wonderful rifle and something I never expected to find here let alone own Smiley.

Nice rifle!  No idea what the screw is for unless for some unusual sight, but that is a wild guess.  maybe Richard 0331 will chime in.   Good find

Do serial #'s match (?), since the fore arm has a metal tip which are found on earlier serial # Hepburns.

Could the screw be a plug screw for a breechseating stud?

Does the end of the set screw rub against the side of the hammer?  Do you see any rub marks there?

It looks aftermarket to me.  Since the .30-40 was a higher intensity cartridge than most chambered in the Hepburn, perhaps the owner found that although the action would hold up to any reasonable loadings, the rebound feature would allow the primer to flow back into the firing pin hole, making the action hard to flick open with the side lever.

This situation happens sometimes with my 40-90-3-1/4 Hepburn, requiring a second snap to drive the primer back so I can open the action.

Frank deHaas recommended grinding the rebound feature off the Hepburn main spring and manually setting it to half cock if the action was to be used in a varmint rifle.  This would keep the full force of the spring and hammer pressing the firing pin forward, keeping the primer flow to a minimum.  This always seemed to me to be kind of a shame, since the rebound works so nicely.  Maybe a previous owner figured that a judicious amount of drag on the side of the hammer would retard the rebound until the chamber pressure dropped.  He would then have the best of both worlds.

Just a guess, but if you shoot the rifle with factory loads and tweak the screw a little as you shoot, you may be able to see a difference in the primer dents.

That is a fantastic specimen.

Looking at the hole with that setscrew removed makes me think it's not factory. I don't think it's for a breech seating tool, as most would use a larger diameter screw to avoid possible breakage. Maybe a weird sight as someone mentioned, or maybe a previous screw was longer and designed as a safety to lock down against the side of the hammer to stop the hammer from moving?

A Hepburn Match B in .30-40 Krag is pretty rare, but any Hepburn in this caliber is not that common. But a Match B in this caliber, and a 34" Creedmoor length barrel is extremely rare! 34" barreled non Creedmoor Hepburns are unheard of! I thought I owned the only Match B with a 34" barrel, so it's pretty neat to see another!
My 34" barreled Match B is a .32-40 B&M. A more common caliber for a Match B than your rare .30-40!

Beautiful Rifle and Congratulations on it now being yours. Breech seating lugs are / should be installed at the center line of the bore. Does that grub screw go all the through or does it bottom out prior too. If it were trying to be used for a seating lug it would be replaced with a longer one that the lug itself would then be screwed onto. But it would also tend to leave a circular mark from the lug touching the action when being tightened up and if not present it could then be ruled out.

Color casehardening will tell you if screw holes are factory or not. If the colors are in good shape you can see the patterns that swirl around existing screw holes. If there's no pattern around a hole, it was likely not there when the action was quenched, and the colors developed.
Notice how all the other holes have the pattern around them?

Good tip on the CC signature around screw holes, thanks Vall. Do you want me to send this one over to keep yours company Wink. I'm still slowly cleaning dried grease off the action so will have a good look. The function of that grub screw really is a puzzle, appreciate all the input/suggestions. That hole goes all the way through the side of the action but there is no corresponding wear marks on the side of the hammer.
Also nice to see another  one in .30/40 Kurt (have you ever shot it?...I'd be interested to hear how that Swiss butt plate handles the .30/40). I have an Axtell Remington mid range tang sight stashed away that will not look out of place on this one until I can find an original.

Does yours have that big old wide front dovetail? I think they're around .450" or so? Mine is missing it's windage front globe, and has a later non windage globe on it. I keep threatening to just order an MVA to put there, so it at least has a windage globe.

Yes, especially when they're oddball dovetail sizes like Remington and Stevens used! If they were the more common .375" size there'd be a chance of finding them, and not paying more than a good gun costs!
I've seen a lot of windage adjustable globe sights with .375" dovetail, but almost none loose from guns with the wide dovetail.

I went looking for that mid-range tang sight and discovered this with it, an Axtell Rem wind gauge sight with spirit level. I'd completely forgotten I had it. Memory is going Cheesy. I really need to do an inventory of my sights/parts/odds & sods cupboard! Lord knows what else I'll find.
Anyway the sights for the Hepburn are sorted for the time being.
