winchester 1876 40 60


Registered Users do not see the above ad.


Hi. Does anybody have loading data for 40-60 Winchester centrefire. I have an 1876 made around 1883. I can buy Accurate. Hodgdens and Vhitavouri powder and I have Reloader 7 & 3031. The bullet is 240 gn round nose with gas check. Any info would be helpful.
Regards Brian.

Hi
Thanks for the suggestion. The problem is that in England we have to have a licence for BP and special storage conditions and I would rather avoid that if I can.
Regards Brian

Well Brian,

Nothing indicated that. In that case try IMR SR-4759 and Accurate 5744. Both of these are relatively bulky, and while not direct replacements for BP they are, either one, good substitutes which will deliver BP range velocities while staying well within acceptable pressure levels for BP cartridge guns in good mechanical condition. If you have a chronograph or access to one you can begin at the starting load and work up with either 5744 or 4759 until you get to listed velocities for the .40-60, 1560 fps per "Cartridges of the World". Bullet weight shown as 210 gr. The only load listed is 21.0 gr. IMR 4198, but the same of 4759 or 5744 should be a good place to start working up.

If you don't ave any dimensional data the COW shows case length as 1.87" and COL as 2.10". Base and rim diameters look like you can use .45-70 brass as a basic case to trim and size.

Winchester 1876

Hi Alk8944
Thankyou for the information, I have used 5744 in my 73 & 86 but I was a little dubious in the 76 as I have only data for IMR 4198. Thankyou once again, I will post when I have test fired a few rounds
Regards Brian.

Wolfe Publishing printed a special titled "The Legacy of Leverguns" about 8 years ago. Both Mike Venturino and Ken Waters had articles on reloading the oldtimers. I did an OCR scan on the Venturino article.

.40-60 WCF

Case length: 1.88 inches
Cast bullet diameter: .406 to .408 inch

The .40-60 WCF should be awarded a prize for the weakest cartridge to be chambered in the largest rifle. Standard Model 1876 rifles weigh at least 10 pounds, but this round won't beat the ballistics of a hot loaded .41 Magnum revolver! Original factory loads carried 62 grains of powder, but my cut-down Winchester .45-70 cases would only hold 55 to 57 grains.

No company makes a bullet mould specifically for .40-60 caliber. I first tried Lyman's 403169 for a 240-grain flatnose (FN), but since Model 1876s in this caliber were cut with a one-in-40-inch rifling twist for 210-grain bullets, the longer bullets only keyholed. Therefore, I did my next loading with cast .41 Magnum bullets from Lyman mould 410660, a 215-grain gas check semiwadcutter. They were sized .408 inch, and loaded cartridge length was 2.158 inches. This combination aver*aged about 4 inches at 100 yards for five-shot groups.

A friend loaned me a beautiful, old deluxe Model 1876 of 1884 vintage for this shooting. Its bore measured right at .406 inch and was still in fine condition. The barrel is 28 inches; the original Winchester factory load was fired in a 30-inch barrel.

Code:
				                  extreme
bullet       powder	   charge    velocity     spread
(grains)                  (grains)     (fps)      (fps)
 210 Winchester factory                1,475        -
	(1/20 alloy)
	GOEX FFg	    55.0       1,480        67
	GOEX Cartridge      57.0       1,467        62
The Waters article is in the attached jpg.

Bye
Jack

I noticed you plan on using a 240 gr round nose bullet.

Never use a round nose bullet in a tube fed rifle!

The recoil has been known to slam one cartridge back against the one behind it. A round nosed bullet can, and often enough does, detonate the primer of the cartridge in front of it.

That would be bad.

Merry Christmas to all.

Exclamation Winchester 1876 (Original)

I acquired a nice 1876 in caliber 40-60 WCF back in 1985. For years I've been shooting it with my own customized handloads. I've been using 45-70 Government brass that I trimmed and re-sized, though one can now buy that brass (with correct headstamp) from Jamison Unprimed Cases.

I'm using Lyman mold 41028, which is 212 grains, sized to .408.

9.5 grains of Unique drives the bullet at about 1350-1385 fps and I can get a consistent 2.5" group at 100 yards with the factory iron sights.

My 3rd Edition of Cartridges Of The World (1972) shows a loading of 21 grains of 4198 behind a 210 grain bullet with a muzzle velocity of 1520. I prefer a little less stress on my favorite antique shooter.
