I bought this rifle off Ron Heilman many years ago. Last century in fact. Was 45-70 and the bore was rough at the breech end. It shot okay but not good enough for BPCRS. Took the barrel to a reputable gunsmith in Puyallup and had him install a .40 liner and chamber to 40-50 SS. I wanted to mess around with that cartridge. My instructions were to chamber it so the head of the cartridge would be flush with the barrel shank face. When I get the rifle assembled find out the chamber was .040 to deep. Case head was .040 lower than the shank face. Gunsmith said bring it back to me and I'll fix it. I had had enough of that so I sold the barrel and installed a GM cut rifled .40 barrel in it and chambered to 40-65. Never finished the project as I was real busy working back then. Years go by and I found an original Hepburn barrel marked 40-1 7/8. Pulled the GM barrel out and sold it. Now the Hepburn had an original barrel in it and it sat around for many years because I was busy. Continued.

Years go by and I then move to Idaho. I lose track of the parts and more years go by. Occasionally I'd look for the parts but never could find them. Finally about three years ago I found a small box with all the parts for the Hepburn.
What a relief! Yesterday I finally started putting it back together. I had it all together except for one screw. The screw on the left side that holds the breech block in place. Just got done making the screw and the rifle is, well, almost complete. I need some front sight inserts. So here it is. Oh, wait, I forgot. Turns out the original barrel in it is not 40 1 7/8 but 45-70. An old rebore. I figure the rifle has been in pieces for about 27 years. And I only lost one screw. A miracle.

That's a great story Joe! What make is the front sight you need inserts for?
You have too many old single shots if you're losing them, or misplacing them!

Reproduction Remington Hepburn sight. May have to make inserts. Can be a bugger getting the correct size.

well, I'm sure glad to learn that you got it together, lacking but a single screw. Lost screws are bad enough, but it's all those loose screws that've caused the trouble.
Happy St. Patrick's Day!

Wes,
Sounds like the Hepburn has gone full circle. Give us a range report when you get a chance. Hope it shoots as good as it looks.

This is the same Hepburn that tried to separate my collar bone from my shoulder bone. I made up a hundred rounds of ammo loaded as such. 10 gr Reloader 7, 60 gr Swiss 1 1/2, Saeco 530 gr bullet. Still have most of that ammo. I often wonder what the hell I was thinking... No, I won't be repeating that trick. The old ammo will be disassembled.

I bought a Hepburn in .45-90 in the for sale section here last year. Got 250 cases made up by BACO from .348 brass and I made up some loads with 4198, but still haven't test fired them at the range. A little intimidated by the .45-90, and those skinny little Hepburn buttplates.

Nice thing about the 45-90 is, it can be loaded just like the 45-70 with extra case length to cover lube grooves. Eliminates the need for special two diameter bullets when shooting very long ranges.
I have considered rechambering the Hepburn to 45-90 since I have a lot of brass. Thinking now that it's all put back together why take the chance it may be scattered and lost in parts for years again.

Thanks Bob. Not so bad if I'd had a button die. Thread was .208 X 28 TPI. My slitting saw was just a bit thin but it worked out okay. Had to dig deep in my pile of stuff to find a sight insert. With the help of a chunk of rubber band it works.
Took it out last evening for test firing. Everything is good. I even fired some of the old duplex loads in it and it did not hurt me. Will be a piece of cake with some padding. So I plan to use it in the upcoming BPCRS match.

Nice old Hepburn. Glad you got it repaired. I have shot rollers, Sharps, and Win. Hi Wall but I find the Hepburn the easiest to shoot. The side lever is so convenient especially in prone.

I've heard that before but I've never had a problem with any under lever rifles in the prone position.
Have had lever/palmrest interference issues however. I have a Pope levered Ballard rifle that can be a bit of a loading puzzle.

I totally agree. I for some reason always had a bit of trouble at times with my lever guns but it could have been my overall setup. I have just become enamored with the Hepburn over the last couple three years.

Lever guns. New fangled repeating rifles. Nothing but trouble and they'll never catch on. Better to stay away from the bloody contraptions.

Range report. Not good. Here is my sight setting at 100 yards. Now I know why I got a killer deal on that barrel. 3 inch groups at 100 yards.

Looks like youll need a windgauge front. Are you going to try something different with ammo to see if you can improve it?

What? The rifle has a windgauge front sight already. Ammonia?
I don't understand your post. Good idea to read the thread before posting.

Started out on Pigs this weekend. Once I got dialed in my cheek was not touching the stock. Got the first six but missed the last four. Hits were all over the place. Just left a message at Krieger Barrels. Thought I had a blank but it is .403-.401 16 twist. Have a .45 Badger blank but is to small. Always somethin.

Jose', you have me plenty confounded here. A few days back you posted that it was gonna work for ya after you range tested and even shot some of those old loads. Now it's sights are that far off?
The three-inch pattern is one thing, but it too might be tied to a sight problem or two. If it gets to be too frustrating, box it up and send here for a trial separation. Oh, crate up the brass and some bullets too, would ya?

Sorry rifleman. I was bamboozled. You would think by now I'd be able to figure these PCs out a little better.
Pat, my test firing was a ten minute drive to my firearms testing place where I stuck the barrel out the window of the Jeep and went bang at the side of the mountain. That was before I even had the sight insert in it. A safety check only.
I have no idea why POI is 10 feet to the right at 300 meters. Everything on the exterior including the sights are in line and normal. The bore looks normal when looking from the breech. When the original barrel was in place the rifles POI was normal. When looking at the rifling at the muzzle with a strong light it appears one side has very light rifling and the opposite side has strong rifling. 3 inch groups at 100 yards is not acceptable accuracy nor the grouping on the pigs at 300 meters. So far I've tried three different types of ammo and three different bullets. It likes the 545 gr Darrel Smithson bullets best. But best is not good enough in this case.
Krieger is not answering the phone or answering calls. Not today anyway. When I called Buffalo Arms they told me all they had was machine gun barrels.

OK, I gotcha now. I was confounded to say the least- assuming that your earlier post said more than it did. Yes, three inches at a hundred isn't good enough- unless you subscribe to the seemingly agreed upon standard of the black gun heroes that we all see at ranges.
So, seems like that thing is going to go back into the bottom of the pile for another long spell. Grab another one instead and make up for the lousy outing you just had.

Difficult finding a barrel blank in 40 or 45. I don't mind lousy outings. Didn't expect to do well at the match. Had fun experimenting with old rifles and being around friends.
Used duplex ammo which was so fun.
I need a new barrel for my Hepburn, Pat. Where can I get one?

I never replaced a barrel on an old rifle. The modern-type I had were done by the 'smith upon me choosing Douglas. Joe, I ain't much on help here. If I had a Hepburn that needed a new tube, I'd be in poorer shape than you are my friend.

Was thinking I might put a liner in it. The rifle is old but nice with matching patina, AKA rust. But I get to wondering about barrel shank runout, or maybe the barrel is bent or some other calamitous defect. If the barrel is bent maybe I could make up a similar jig to straighten it. Worked perfect on this drop axle. Or use the mill as a press. Nah, a new barrel is the best solution.

More barrels are bowed than we probably know.
I used vee blocks as far apart as I could get them in my hydraulic press to straighten a barrel from a Stevens 44 that looked like a jump rope swinging between centers in my lathe. It had .060 runout. It took a considerable over center push to make any difference. I got it to .005 and called it good. I sold the rifle to a friend who has sent over 2000 rounds through it the last 3 years at silhouette matches, load development and practice.

I'm gun shy about taking the old Hepburn apart. I might not get it back together. Think I just bought a .40 barrel.
I've seen a few barrels that were bent bad. Green Mountain sent one to me that had a bowed bore but straight on the outside. Easy to see when it's spinning in the lathe. I had a barrel with shank runout. Not sure what I did with that barrel. Can't remember.
