Breathing New Life Into Old Cartridges

By Bob Campbell published on in Ammunition

We probably have more handgun calibers than we need. Some should be allowed to die a quite death. Just the same, during my career I remember scrambling to locate and actually fire such oddities as the 7.65 French Long, .32 Rimfire, and the .41 Rimfire. Quite a few old numbers might be useful even in modern times. Then there is the family heirloom that we just may want to fire.

Enfield revolver opened with ammunition

The Enfield has been fired extensively and is a fun revolver to use.

Firing an old handgun that once belonged to someone 100 or more years ago is like shaking hands with the past. We just like to get the feel of the implements of the day. However, our overwhelming concern must be safety. There have always been more cheap guns than good guns, and some were none too safe even when they were new.

For example, the .41 Remington Derringer I tested is made of soft iron. It is famous for breaking at the hinge point. however, it sends its bullet along at about 550 fps! On the other hand, the .32 French Long is like owning a .32 Magnum automatic. I have handloaded the Hornady 60-grain XTP to well over 1,150 fps in this well made pistol. In a pinch, some of the older handguns might be pressed into service, if there just isn’t anything else available. But otherwise, their use is for recreational value only.

.38 Short Colt and .38 Long Colt

These cartridges are immediate ancestors of the .38 Special. The groove and land diameter varied in early handguns. The .36 Colt Navy had a respectable reputation due to the fact that it had enough velocity to cause expansion in its .375-inch ball.

.32 Rimfire loads were quite a catch—so anything is possible!

When cartridge conversions were undertaken, the .38 Rimfire was developed. The outside lubricated heel-based bullets picked up a lot of lint and were not as robust as the later inside lubricated bullet.

The centerfire .38 Colt cartridges featured the type of crimp we know today. Firing them in Navy Colt conversions gave problematic accuracy at best. The later purpose designed .38s, such as the Colt Lightning double-action revolver, were more accurate.

I own a rather homely Hopkins and Allen double-action .38 that was minted some time prior to 1900. There were many more cheap guns than expensive guns then—the same as today. The Hopkins and Allen was among the more useful. As a hideout, or for those on a budget, the gun had appeal. I checked mine as thoroughly as possible for safety. It locks up tight and functions.

I do not recommend firing such an old revolver, but it is what I do. I test fired the piece under controlled conditions, using a remote trigger and fixture. I used custom grade ammunition from Jamison Brass and Ammunition. This company loads difficult to find ammunition and offers brass for reloaders. It ended up working quite well.

The Colt Police Positive is a piece of history. Fiocchi loads are clean burning and accurate.

At seven yards, the old .38 would group three shots into 4 inches. This was a good standard for the day. The same load grouped three shots into 1.1 inches at 25 yards with the Colt Python. These loads are well suited to older revolvers, such as the Colt Lightning and the Colt 1892.

.38 Smith and Wesson

The short, fat .38 Smith and Wesson will not chamber in the .38 Special. If you have a .38 Special Military and Police that accepts the .38 Smith and Wesson, it is an ex-British Victory Model. Many of these chambered for the .38 Smith and Wesson, and famously loaded with a 200-grain bullet, were bored out after the war to take the .38 Special. This isn’t rechambering! These butchered guns swell cases when fired with the .38 Special, since the .38 Smith and Wesson has a smaller head diameter. It would be a disaster to fire a .38 Special +P in these revolvers.

There are three classes of .38 Smith and Wesson revolvers. The first are the break top type, usually five shot, double-action revolvers. Examples of the breed were manufactured well into the 1930s. H and R offered a version at least into the early 1970s, with a long barrel and target grips. These revolvers must be fired only with standard loads, which means a 146-grain RNL bullet at 700 fps.

.38 Short Colt and .38 Long Colt loads

.38 Short Colt and .38 Long Colt loads are cutting about 700 fps with 125- and 158-grain bullets, respectively.

At one time, conversion cylinders for the .38 Special wadcutter were offered. They are very rare today. The second class are the large frame revolvers, such as the Colt Police Positive and the Smith and Wesson Military and Police. In these revolvers, the short .38 is a very accurate loading. These revolvers will take .38 Special class pressure. A handload worked up in these revolvers is versatile, but if it found its way into a break top pocket gun, the result would be a disaster.

The next class is the break top Webley and Enfield type. When the British adopted a .38 caliber revolver and replaced the .455, they realized that engineering would only allow a short cartridge. The .38 Smith and Wesson with a 200-grain bullet was adopted. Sometimes called the .380 Revolver or the .38/200, I have handloaded these with the Magnus 2200-grain RNL bullet to 775 fps. These loads demonstrate excellent penetration.

For this test, I selected three representative revolvers. First up was a vintage Iver Johnson top break. I have fired it a little and found it to be safe. Next was an original transitional Colt marked New Police, but it is a Colt Police Positive.

The six-shot double-action-only Enfield is, in my opinion, the best designed combat revolver ever manufactured. The high sights are very fast to pick up, and the revolver offers excellent hit probability. With the difficult to find speedloaders, it is a fast revolver to reload. The problem is the cartridge. It isn’t powerful enough for personal defense. Just the same, the Brits got by with the revolver as a badge of office and taking prisoners at gun point.

Enfield cylinder loaded with Buffalo Bore cylinder

There were no excess pressure signs with the Enfield/Buffalo Bore combination.

I have fired the Iver Johnson with PPU ammunition. It breaks 570 fps and from the Colt Police Positive, 588 fps. The Colt isn’t made for accuracy, but a two-inch 7-yard group was fired. Fiocchi’s 146-grain RNL is more energetic and breaks 717 fps from the Colt, with superior accuracy. Firing from the Enfield DAO with care, I have fired a two-inch 15 yard group.

Buffalo Bore offers a modern loading that is designed to get the many Military and Police and Official Police revolvers up off their knees and into useful personal defense category. This load must NEVER be fired in break top revolvers of the early 20th Century type. The Enfield, however, is rated for this load. Just the same, use caution.

When handloading the .38 S&W in solid frame revolvers, I have coaxed a 158-grain SWC to 850 fps. Buffalo Bore dropped the weight to 125 grains, and using a hard cast SWC achieves 917 fps from the Colt Police Positive and 1,015 fps from the Enfield. This certainly gets the revolvers into the useful range. I keep an Enfield stashed in a hideaway in this 110 year old house, and it is loaded with the Buffalo Bore loading.

At the exact moment of firing, there is no muzzle flip with this combination—a big plus in the view of the British Army that adopted the piece.

.32 H and R Magnum

The .32 H and R Magnum isn’t an older cartridge, but to the best of my knowledge no revolvers are currently chambered for this cartridge. My only .32 is whimsical purchase that I have enjoyed very much. After much good service with the Heritage .22 revolvers, I obtained an example of their 3-inch barrel, Birdshead grip revolver, a piece long out of production. Most factory loads do not impress. Buffalo Bore offers a 100-grain JHP at a strong 1,100 fps. This gets the revolver into field-grade power, and would serve against coyote at moderate range. A hard cast 115-grain bullet from Buffalo Bore achieves about the same velocity. I like these loads. This little gun isn’t that accurate, but it is easy to use well, and it is certainly up to the task of popping pests to 15 yards or more.

With careful searching you will be able to get older revolvers up and running and find them useful for recreational shooting. Back to the wall some will serve for personal defense and give the owner a measure of peace of mind.

    I have a Webley Mk 6 and need all info I can get , also ammo and who still makes .455 rounds . What steps I need to take before I go to the range to make sure it is safe to fire since it is 102 years old and looks in good shape. My thanks DDog


    • Cmac


      First visit a gunsmith and have the gun checked. Check Cheaper Than Dirt, among others about the ammunition. Someone makes ammo for outdated/obscure calibers (although I don’t remember who at the moment) and I have seen different types listed on one or more of those sites.

    I have a m&p model 17 in a 32-20 could use any info on the gun and ammunition, have two boxes of 32-20 rifle ammo , can I use it, the gun in in great shape, thanks big al from Oklahoma.


    • RKC



      The M and P prior to 1957 doesnt have a designation and the .32-20 was the Model Ten after ’57. Which one do you have?
      Ammunition marked RIFLE ONLY is dangerous for the handguns. However there is some collector value for the ammo so you are not stuck.
      .32-20 WCF is fine for the revolver, however, rifle only marked boxes would be dangerous. What ammo do you have?l .


    • D. Brian Casady


      Big Al, you might want to check to see if the .32-20 ammunition will fit in the revolver. Most of the rifle ammunition in that caliber is slightly longer than the pistol ammunition was. It is also loaded to higher pressures most of the time. If it doesn’t fit due to length, avoid trying to make it fit. Most reloading manuals only have the rifle loadings. There is probably a good reason that they are not listed fot pistols. Just my opinion.
