#3 remington hepburn
|
well i've been wanting to build a big bore rifle for a while now with no real luck when my dad called he found his remington hepburn action that he had lost for 20 years. not wanting it he gave it to me so whats a good big bore caliber for that type of action .i beleive it was orginally 38-55 i thought of 450-358,400 jeffery or maybe a 450 nitro express if the action would hold it

Remington Hepburn's are black powder actions,sell it to a collector and get something made for nitro.

Lucky!
I'd love a remington Hepburn someday. In my opinion these are the nicest American single shot actions (that I've come across) so far.

The problem with Remington Hepburns is stocking them.
Fitting a stock with minimal drop is a real problem because of the way the tangs are angled.

The Hepburn has its firing pin at a steep angle. This requires precise bushing and fitting to prevent the firing pin being stuck in the primer. That may be the biggest impediment to greater than black powder pressures. Otherwise, the action is strong.
Believe it or not, my varmint shooting partner from the early 80's had a Hepburn built up in the .22/30-30 Ackley Improved. The action held this cartridge fine, but he experienced problems with firing pin hangup early in the rifle's career. A little tweaking did correct this problem. Personally, I would not be so bold with a Hepburn unless the breech block had a major re-build on the lines of a Neidner-Mann treatment. I don't know if this is possible with the Hepburn block.
As said, stocking this action presents very limited possibilities. An all-out schuetzen style will be your best choice if you want to be true to the action's history. I once saw a beautiful schuetzen rendition of a Hepburn in fabulous flame colored fiddleback maple done by Hal Hartley. Something like that in a traditional caliber from 32-40 to 45-70 would be a lot of fun.
The only Hepburn in my past ownership was chambered in .22K Hornet. It retained its original wood from Remington. For some reason I could never get acceptable accuracy from it (the Hornet and K Hornet are notoriously difficult). I let it go for other horizons.
My very favorite vintage American action is the 1878 Sharps Borchardt. My next favorite is the 1885 Winchester High Wall. Sadly, all are gone to my demanding double rifle habit.

Curl- THAT is lovely. The midrange sight fits nicley in front of the comb. A long range staff might hinder cleaning.
TKs for posting that picture.
They do made nice BP ctg. rifles.
The angled firing pins also hinder Sharps 68 and 74 actions.
If stuck and the block is dropped, oft times, the end of the pin gets broken.

I have one of those GM tapered octagonal barrels in a Winchester heavy #3 or #3 1/2 taper - 35" long, 1" at the muzzle. Mine is chambered for the 1.9" case as I used my .458 2" reamer "held back". I had it threaded for my modified 1868 Sharps action.
With it's fairly long leade, smokeless loaded bullets can be seated out considerably and with it's bl. length, it gets approximately 250fps higher velocity than what is noted in Hodgdon's data - ie: for their listed 400gr. jacketed at 1,640fps, I get 1,850fps a pressures well under 24,000CUP. My loaded length is the same with those bullets as if loaded for a Marlin. Of course, my rifle cannot take the pressure the lever guns do, so I hold them to loads listed below 28,000CUP.
1,850fps is not shabby for a Sharps with 400gr. bullets.
Incidently, this barrel and load made a witnessed 7/8", 10 shot group at 100meters, off bags. Very accurate barrels. Got mine from trackofthewolf. This was when using a cheap $300.00 tang mounted aperture sight and #110.00 hooded front globe (Sharps design) with aperture.
With an original Sharps Carbine open rear sight and silver blade front, I've made a number of 1 1/2" 3 shot groups at 100 meters, witnessed by my brother, using 42.0gr. Benchmark and 506gr. cast RN w/GC @ 1,500fps.
Note the action is a modern Italian action in 4140 steel. The design is from 1868 - so low pressure only.

Mine was .4565 as well. Bit tight - OK with jacketed .458" bullets as well.
I managed to pick up the 495gr. Schmitzer(spitzer) Lyman mould was well as the #457125 525gr.RN, both for $20.00, due to both being slightly undersized. They cast .4575" in my alloy and my rifle loves them, smokeless or black powder.
Those 18" twist GM barrels shoot!

Re: #3 remington hepburn

The fist day benching my new GM barrel, the 18" twist, I was shooting 400gr. RP FN's & had worked up to 48.0gr. Benchmark in the 1.9", .45/60 case.
Chrono'd speed was 1,850fps in the 35" bl.
Using an Italian copy of a Soule Tang Sight and globed Sharps front with aperture, I managed a 7/8", 10 shot group off the bags at 100 meters. It was absolutely amazing. Most loads with REAL black powder run from 1" to 2" at 100 meters, 5-shot groups using same sights using the afor mentioned bullets. My rifle seems to prefer the 525gr. #457125. A blow-tube is used between shots and is shot 'dirty'. I have only just started working on the BP loads.
42gr. Benchmark and 506gr. RN GasChecked Lyman bullet (478gr.?) managed several 1 1/2" groups using open Sharps Sights, V and silver blade.
These loads were safe in my Sharps with the huge, BP firing pin.
The rifle with the Carbine Rear Sight. An 1868 Italian action that I finished from the rough milled state, filed on the hammer a bit to make it look like a 74 hammer, then had the action metaloyed after polishing. Thus, the colour.
