I was a little surprised when I began visiting these Internet forums and saw so many questions regarding +P .38 Special ammo. It seems each new day brings yet another post asking about the safety of using factory +P ammo in one gun or another. I always assumed the short answer was that if you had a Star, or Ruby, or some other gun that might be questionable as far as strength is concerned, then stay away from +Ps. But many shooters seem concerned about using this ammo in quality guns of recent manufacture* and I didn’t expect that. I saw many inquiries about K frame S&Ws using +P and I found it odd that anyone would worry about using factory +P ammo in such a gun. Then I started seeing postings from owners of .357 Magnum revolvers asking if +P .38 Special ammo would harm their guns. One forum member was concerned that +Ps would damage his Model 28 S&W.
Come again? I don’t know what caused such a mystique to surround +P ammo to make people with N frame Magnums think it’s too much for their guns, but it strikes me as overblown all out of proportion. The fact is that +P isn’t “all that” anyway. Winchester, Federal and Remington list the velocity of the 125 grain +P at 925-975 FPS. These velocities are actually fairly mild. I have shot many rounds of Remington 125 grain +Ps in a 1942 S&W Military & Police revolver and I can literally shake the fired cases from the gun without using the extractor. In my opinion these loads are actually pretty mild and show no sign of even moderate pressure in any of my guns.
Why is everyone so terrified of +P? I believe that +P is a marketing ploy used to sell ammo and any perception that this ammo is powerful is a myth.
The factory ammo made back in the 1960s and 1970s was hotter than that made today. I have seen the specifications for standard .38 Special ammunitions from a 1940 catalog listing the velocity as 960 FPS with a 158 grain bullet. This load would clearly develop higher chamber pressure than the current +P load and yet it was used for decades in all models from Colt and S&W without incident. The current +P is really about what the .38 Special should be in standard form. But note that the standard load is no longer what it once was, either. In 1940 it was the 158/960 that was considered standard. During most of my youth the load was advertised as 158/870. Current specifications are pretty wimpy at 158/750. Again, we see the ammo companies reducing the loads over the years. The current +P (which means +Pressure if you didn’t know) is really only +P when compared to current standard loads. Stacked up against past standard loads the +P looks pretty anemic and the current standard load is truly pathetic.
The fact is that +P is only called +P in comparison to the standard .38 Special loading, not because it exceeds the pressure limits set for the caliber. The SAAMI pressure limit for the .38 Special is 21,000 PSI (the .357 Magnum is 35,000 for comparison). The standard load for the .38 Special as offered by Winchester, et al, generates 16,500 PSI. This is so far below the maximum allowable as to be ridiculous but the ammo makers fear lawsuits from people using the ammo in cheap guns. The +Ps from these manufacturers run about 18,000 PSI. This is more than the standard loadings (hence the +P designation) but is still far below the maximum allowable pressure. Those "really hot +P loads" from the specialty manufacturers like Cor-Bon, etc., are simply loaded to the caliber's full potential of 21,000 PSI and should be perfectly safe in any quality arm in good condition.
So why are we seeing these less powerful loadings? Because there are some guns out there that are not well made. Because of liability concerns the ammo makers must load their products to pressures that are safe in these lower quality guns. They mark the "high pressure" loads as +P (even though as I noted they really aren't high pressure) to give them legal cover should someone hurt himself shooting this ammo in a cheap Spanish S&W knock-off of dubious quality.
S&W ran advertisements in the 1930s and 1940s specifically stating that the .38/44 load, which pushed a 158 grain bullet at an advertised 1125 FPS making it far more powerful than the current +P load, could be used in the K frame revolver. Colt ran similar ads for using this ammo in the Detective Special. If these 1930s-era medium frame revolvers could handle the 158/1125 Heavy Duty loads, why should anyone worry about the same guns shooting the current 125/975 loads labeled as +P?
Lee Jurras started Super Vel in the 1960s. This was maybe the first of the specialty ammo companies and he offered truly high performance .38 Special loads. I have some of the 110 grain loads and they clock around 1300 FPS. Based on this I would guess his 125 loads would go around 1200 or so. This would be a true +P load but it’s still lighter than the old .38/44 load. I don’t recall seeing or hearing of guns being damaged by this ammo.
Check out a reloading manual from the early '70s. The Speer #8 from 1970 has one listed for the .38 Special pushing a 158 JHP to 1,250 FPS, one for the 125 grain bullet at 1426 FPS and one for the 110 grain bullet at 1536 FPS! A 1971 Sierra manual shows a load for the 125 grain .38 Special at 1250 FPS. Sort of makes that factory +P at 975 seem less intimidating, doesn't it? Now, of course, new manuals don't include listings that are this hot. Now they stop at about the same levels as the factory +P. Why? Lawyers and lawsuits are the reasons why. The reloading manual publishers are just as scared as the gun and ammo makers about being sued. Fear of lawsuits is the same reason the gun makers caution against the use of +P ammo. They also say don’t use reloads. They have to say this on advice of counsel to protect themselves.
I load 125s at 1,100 FPS in my .38 Special carry guns. This load came from the 1970 Speer manual and is not the top load listed. I have shot many rounds of it through both K and J frame guns and they seem to work just fine. Recoil is slightly more pronounced than with standard ammo, but the cases fall from the cylinder with no sticking and I see no signs of excessive pressure. Just for fun I once put 6 rounds of this ammo through an old small-frame Rossi revolver. Nothing bad happened although I wouldn’t advise using this ammo in such a pistol.
Ask yourself this question: Would any ammo maker in today's litigious environment sell any ammunition that would be unsafe or harmful to use in the typical gun that a consumer may own? If factory +P were really hazardous would Winchester, or Federal, or Cor-Bon sell it to the general public?
With all the many, many questions regarding the safety of +P ammo, there must be many reports of blown-up guns, right? How many guns blown-up by factory +P ammo have you seen? How many guns blown-up by factory +P ammo have you heard about? I have been participating in the shooting sports and studying firearms since 1967 and I know of absolutely NONE.
Certainly, using a gun causes wear. A gun is a machine and using any machine will cause it to wear. Using hotter ammo will likely accelerate the process to some degree. But a quality gun from S&W or Colt or Ruger will not blow up with +Ps. Nor will it excessively stretch the frame or split the barrel in my opinion. It will possibly wear a little faster, and I doubt if anyone could predict how much, but I think the added wear on a good gun will not be all that much. The gun would probably still last longer than the man who owns it.
I admit to paranoia about warm loads in an alloy-framed gun. I do not have any alloy revolvers but if I did I would stick to standard ammo even though it seems obvious from my research that current factory +P is hardly any warmer than the original standard .38 Special load. In a steel gun of good quality I have no concerns at all about +P on a regular basis since I consider factory +P to be nothing more than standard pressure, anyway.
This is just my opinion based on personal experience and research. There are differing points of view. Some replies to the +P question are quite adamant about avoiding regular use of this ammo. Others advise occasional use. Some say only carry +P for defense but don’t use it for practice at all. The fact that there are so many answers to this question tells me that there is great confusion on this matter. I’m a simple man and I take a simple course to the truth. I do basic research and try to find the facts. I have presented the facts as I see them. All one must do to find the truth about current factory +P ammo is look at the specifications. I submit that a 125/975 load is hardly high performance, and certainly nothing to cause concern for owners of quality revolvers. All are free to disagree.
Some forum members have accused me of being irresponsible in recommending the loads I mentioned. Of course, I am not recommending anything, only stating what I do. Also, all of the loads I use came from reputable reloading manuals. If the loads were safe in 1970 I don’t see why they aren’t safe now, but I don’t recommend anything to anyone. Each of us has to make our own choice. If you think any of the loads I mentioned are too hot then avoid them. If you are in any way uncomfortable with +Ps then stick with standard loads.
* The manufacture and tempering of steel was imprecise before around 1930 or so. Any of my guns made before this date get reduced loads just to be on the safe side. Note that early S&Ws, those made before around 1918, had cylinders that were not tempered at all. A similar situation likely is true with Colt revolvers but I have no specific knowledge of when Colt began tempering their cylinders.
PS:
This same situation that has affected the .38 Special occurs with the .38 Super. The original loading for the Super was a 130 FMJ at nearly 1,300 FPS. But the Super cartridge is the same physical size as the old .38 ACP, just loaded to higher pressures so the ammo makers started fretting over some yahoo stuffing Supers into his 1905 Colt in .38 ACP and spreading parts all over the range. That’s why Super cases were nickel and the .38 ACP were brass until a few years ago, so shooters could instantly recognize which ammo they had. I was curious a few years ago when I noticed that they stopped doing this and I saw Super ammo in regular brass cases. I guess there’s no need any longer since factory Super ammo now clocks about the same as .38 ACP. The last box I checked ran 1,120 FPS, only 40 more than the ACP. They have down-loaded the Super to nearly the same level as the ACP. No lawsuits. Of course, the Super isn’t so… super… any longer, is it?
