Hello SSS,

Thought I'd post several archived posts that pretty much dealt with loads for the Romano Spencer.  Maybe some of the presented information will be of value to some of you.  Two Flints

Romano Spencer Load Information

Posted by E.W. Johnson on N-SSA on Tuesday, January 3, 2006

As many have said before, using the right bullet, bullet length and making sure your follower and upper breechblock are right makes all the difference in getting your spencers to work properly. In my two origonal Burnside M1865's, I've had good results with both the Rapine spencer .520375 sized to .517 and the smith .515365 also run through the .517 sizer. The spencer bullet is seated and crimped at 1.650" and the smith bullet at 1.598. The oal are different due to the different shapes of the bullet ogives. The upper breechblock must rotate between the cartridges in the magazine. It must push the 1st out onto the breechblock and push the 2nd back into the magazine allowing the breechblock to rotate, chamber the round and close. If your bullet profile and oal is correct, check to see if the front top edge of the breechblock is too sharp. If it does not have a slight raduis to the edge, It has a tendency to catch (grab or cut into). the soft bullet and cause a jam. The top front edge of the breechblock must pass between the two cartridges, picking up the 1st and pushing the 2nd back into the magazine. My carbines do work best if the muzzle is inclined towards the ground. Most of the time, they can be cycled from the shoulder but it is not as reliable as with the muzzle pointed down because the extracted case falls out of the action instead of sometimes laying in the cartridge guide (follower). These guns are alot of fun but you must remember they were very different from the Henry repeater, more like a repeating singleshot (kind of like a singleshot with a magazine). Still a lot quicker to load than the rifled musket. Have fun with your spencers!

...
A few month back on the SASS wire, someone posted smokeless powder load data for the 56-50, I believe with either 5744 or Some hodgdon's powder. I thought I printed it out, but can't find it. SASS wire has purged it. Anyone have it or any 56-50 smokeless data. BP and Triple Seven are no-brainers (fill the case), but I have no smokeless data. Ken at Ten-x says his smokeless loads go 1300 FPS and BP substitute go 1100 FPS, but the ingredients are a secret!

These loads are safe only in my original Spencer 56-50 carbine:

All with BELL 50-70 brass cut & trimmed to size & annealled.

350gr Rapine bullet#520350, over 16gr of 2400 powder, tuft of poly fiber fill to keep the powder over the primer. Chrono. is 1000fps.

Unique powder also is good for easy reloads, 9gr.

I had no luck with 5744. It would need a filler.

I was on my own when I started and used 45LC Colt SAA loads to give me a starting point, these loads have worked good for me for 10 years or so.

Check the post on best groups with a Spencer. I have been able to wring out 3-1/2" at 100 yards. But ArizonaTrooper has a B.P. load there that cuts that by more then half.

Anything much over 1050 FPS with a 56-50 Spencer is to much. There is such a thing as rearward bolt thrust, the wider and heavier the bullet the more the rearward bolt thrust. A Spencer 56-50 with it's .520" caliber bullet probably has more rearward bolt thrust then most other calibers we shoot. An example is the 1873 Winchester copies, a 357mag that operates at 37,000 psi is available but not a 44mag. ( But EuroArms use to import a 44mag 1873 Win.). The Spencer design only has so much breech locking surface.

You CAN duplicate black powder pressure & accuracy with smokeless powder but you can also fast exceed it.

Like I said at top, these loads are only proved safe in my Spencer.

........................................................................................

This is the answer I got when I e-mailed the makers of 5744.

Caliber: 56-50 Spencer.
Barrel length: 22”
Powder: AA 5744.

Bullet weight: 300 grains.
Start load: 19.0 grains (1100-1200t/p/sec)
Maximum load: 22.0grains (1200-1300 ft/p/sec)

Bullet weight: 350/360 grains.
Start load: 18.0grains (1000 -1100 ft/p/sec)
Maximum load: 21.0 grains (1150 -1250ft/p/sec).

Bullet weight: 400 grains.
Start load: 17.0grains (900 -1000 ft/p/sec)
Maximum load: 20.0 grains (1100 -1200ft/p/sec).


Here is what I have experienced so far with smokeless loads in the 56-50. Since there was (is) no load data available, I started out with low end and reduced 50-70 loads and tested them in my 50-70 carbine. Since the 50-70 is basically an elongated 56-50 I figgured that this was a good place to start. XMP-5744, IMR 4198 and SR 4759, while providing reasonable accuracy, are all very dirty, leaving so much residue in the chamber that it had to be wiped between shots in order to chamber the next cartridge. My best results have been with Unique and IMR 4227. While both burn fairly clean, the IMR 4227 has given better results than the Unique and in the loads that I use it nearly fills the case to the base of the bullet. In addition, it meters through a powder measure with great accuracy from charge to charge. The best load so far has been 23.5 grains of IMR 4227 with a 335 grain bullet, cast out of 20:1 alloy. This has given 2", 5 shot groups at 50 yards and I'm still trying to refine it some. The bullet is from a Lee, 500 grain mould that I modified by turning off 2 grooves and two bands from the base. This provides a bullet with a large flat nose. I didn't want too pointed a bullet in a magazine right next to my face. I'm using a homemade lube on them, sized 0.512", with Winchester WLR, large rifle primers in Starline brass. I hope that this helps and at least gives you a starting point for your smokless loads.

Romano Spencer Load Information

Posted by J. Wimbish on N-SSA on Tuesday,  January 18, 2005

I purchased a set of 4D Spencer dies from Larry Romano. These dies work very nicely. I also purchased a bullet mould from Romano. The bullets should be sized to .512 inches. I use lead that has only been slightly hardened. The Romano Spencer has about a 1 in 36 twist so using soft lead is pretty much out of the question.

The overall length of the cartridge should be no more than 1.565 inches. It can be a little less without causing problems. Use a medium to firm crimp. I use only 33 grains of Goex 2f in my Spencer and get excellent accuracy. Go with a magnum primer. I use Federal 215's. If you choose to shoot a hotter load, like 40 grains of 3f you will want to go with harder lead. However, from an accuracy standpoint there is no need to do this. The lighter load delivers excellent accuracy and is comparable to extremely accurate loads that I shoot in the Maynard, Smith, and (relined) Gallager.

I have also had good luck shooting the 365 grain Rapine Smith bullet in the Spencer. Use hard lead and size to .512 inches. This bullet sizes down very easily.

I have shot Accurate 5744 in my Spencer as well as black powder. The Spencer is a relatively easy gun to clean, so I saw no reason not to shoot black powder in it.

I have one of Larry's guns, and it's a work of art. Getting it to shoot took some work, but once you find the magic formula, it's right on. Here's what I use (on Larry's recommendation):
Brass: reformed BELL .50-70 cartridges from Buffalo Arms Primer: magnum large pistol primer Use the hottest you can get.
Powder: 40 gr. FFFg GOEX. Rumor is that Swiss will shoot even better.
Lube: pan lube with SPG or use lubricizer
Bullet: Romano Spencer mould cast in 9 parts linotype/1 part pure lead.

No filler or wad, so be sure to wipe any lube off the base of your bullet before you assemble the round. And like Ken says, use a heavy crimp.

That bullet alloy gives you a Brinell hardness in the 19 range, which is harder than you can get with wheel weights or tin alloy, even quenching them. I got a pack of 100 from (now defunct) Liberty Shooting Supply, and I was amazed at how well they shot. It was like night and day compared to "hard" lead bullets I'd made, and that's what I've been casting myself ever since. That was really the key to getting my gun to shoot. With wheel weights, I was shooting "minute of barn door" groups. With the really hard bullets, it became a pigeon killer.

Favorite Bullets for  ArmiSport Spencers 

Posted  by Hoot- 3rd GA on N-SSA, on Friday, December 23, 2005

My Armisport Spencer prefers the the Romano Rifle Company .50 cal. bullet sized to .516. It has one large grease groove between two long driving bands. It is long enough to produce the AOL of 1.5" to 1.6" necessary to feed through the magazine.

Ammo for Taylor Spencer

Posted by Hoot - 3rd GA on N-SSA, on Wednesday, October 12, 2005

I have put over 2000 rounds through my Armisport Spencer and have found the following to be true for my carbine. The overall cartridge length must fall between 1.6" and 1.7". You can use the 50 cal "Smith" bullet or the 50 cal. Romano bullet seated and lightly crimped into Starline brass. The nose of the lead bullet should be flat to prevent ignition in a tubular magazine, but it's shape doesn't seem to affect feeding into the chamber. Production Starline brass is too small in diameter to seal in in the chamber so it must be expanded by fire forming with a heavy charge or by using an oversize expander ball in the 56.50 die set. Enlarge just the upper end of the case because Starline tapered the inside toward the base so expanding too far down inside the brass would ruin it. I never resize the brass during reloading ... just use the depriming pin to knock out the primers. The lead bullet must be at least .516. If everything is right, the cartridges feed perfectly and there is no fouling of the brass or block. One other quirk... if you leave the chamber damp after cleaning the bore......the cases seize up and refuse to eject smoothly. Every time I shoot it, I learn something new. During the BLR match at this last nationals, one of the screws holding the firing pin cover backed out locking up the block so it wouldn't cycle. Keep both those screws tight. There is alot more but I have to go for now.
