ok I reload 9mm ive reloaded thousands Ive got 800+ rnds loaded right now...I HAD 1 pack of 100 small rifle primers winchester I cannot find that package are they the same size as small pistol? IE would they fit?


I think i may have loaded the small rifle primers instead of small pistol in my 9mm loads

how big of a problem is this? I have NO idea which batch what kind of problems could i have?
 
A friend of mine did just the opposite this year Large Pistol into .308 cases.
He thought it shot just as good or better. Good thing it was just a practice day.
This of course is never recommended. :mrgreen:

I will agree with Gatehouse about increased pressure.
 
As an experiment I loaded a few .357 cases with small rifle primers and a few with small pistol primers.
These were light loads but speed was slightly less with the rifle primers.
I wondered if the rifle primer forced the bullet out of the case more than the pistol primers while the powder was starting burning, lowering the pressure.
Since I'm using them in a lever action, I'm going to do accuracy testing and probably use rifle primers from now on.

As long as your firing pin will fire them, you should be OK.
I gather revolvers are known for weaker firing pins than semi's.
 
With the exception of .38 Special, I don't bother buying small pistol primers. I use small rifle for everything. Of course that also means my loads have been worked up using them, not as an inadvertant substitution like you may have done here.

Have a look at the loading manuals (several) and try and figure out where your load stands. If it's at or near the top of the recommended powder charge, I'd pull the lot and start over. If you've got a reasonable safety margin (5,000CUP or better) then I wouldn't sweat it.

While not a suggestion to load without discretion, most posted loads in North American manuals are still a little lighter than the European specs, and there is a bit of wiggle room. Just don't wiggle too much :shock:
 
Small rifle primer have a harder cup and are much hotter than small pistol primer.
Using small rifle primer in a pistol or revolver can get you more wear and tear or the firing pin ( firing pin breakage in the long run) If loaded close to a max charge - you take the risk of overpressure and gun damage. This can also be detrimental to accuracy. The primer manufacturer know better - use the proper primer for the application.

Contact148, if your 9mm are not close to max load, you should not worry. Go ahead shoot them.

It is foolish to use small rifle primer on anything other than the purpose that they are made for. We call that looking for trouble...

We've been doing it in IPSC for 20 years or more to combat pierced primers and metal shaving in the firing pin hole. I'm calling BS on firing pin breakage. The cups are thicker to resist pressure, but they don't offer a much harder surface for the firing pin to hit. Since they are thicker, it takes a greater impact force to cause enough deformation to ignite them, but that doesn't translate to harder metal.
 
Canuck223,

Common read what you write... the cup is harder and not much ticker - mesure it up for tickness to judge by yourself !! The cup material is harder. The rifle primer are also hotter and not to be used in published reload data for handgun. The rifle primer will increase pressure.

Shooting IPSC for 20 years doesnt mean you have a wide experience. I know shooter that shoot IPSC for 20 years + and do not reload. I also know shooter that still shoot IPSC with their original CZ75 and the same 9 MM load. After experimenting they settle on one load and stayed with it. Since you started it..


I shoot IPSC since it started in the Province. I used a 9X21 wich mandate a small rifle primer to avoid primer flow and pierced primer. The use of small rifle primer cured that but after one reload - sometime two - the primer pocket gave away and the case were scrapped. Firing pin ? always a back up and we changed one or twice a year for a new one. This was hard on the gun and inspection and maintenance was extensive. The 9X21 was punching a 124 grains to 1450 FPS. I reload 25000 rounds a year . I reload all I shoot and have been at it for more than 30 years. That was the time of the 9X25 development. Remember those ?? I can follow you on this also ..I owned one.


The bottom line is this : manufacturer and powder manufacturer know more than you and me.
Do not use rifle primer when a pistol primer is needed : period
They write it in all their published manual and documentation. They also state that using rifle primer in handgun can be detrimental to accuracy. Follow the rules made by people in the know.
You can play all you want with your safety but do not use your experimentation as a basis to give public advice that can lead to broken gun and injury.

What need to be promoted is safe reloading and shooting. Not foolishness.
 
I guess I'm bad too. I use Small rifle primers for everything except 38spl.

I have not seen any pressure increase either, but again, these loads have been worked up using the rifle primers from the start!
I have not tried the large pistol/large rifle swap.

As far as IPSC, I've been shooting major 38 super, some at 180+PF,with small rifle primers for 12-13 years and have never had a firing pin break. And I always get many reloadings from the brass before it is scrapped.

I am going to check my supply, but, I'm sure I have Fed 200 primers that are marked F200 small rifle and F200 small pistol magnum. Need proof? Page 26 in the 4th edition Hornady manual.

So when the manufacturers, who know more about powder and primers than you and me :wink: , seem to use the same primer for magnum small pistol and small rifle, how different can they really be?
 
I have Federal small rifle primers that are marked "small rifle primers and high velocity pistol"and I have used them in 357 magnum pistol loads and never had any problems with them being too hard or breaking anything. As for experience I have only been reloading and shooting handguns for 25 years. :wink:

Most likely because the 9x21 loaded to a standard 9mm x 19 OAL to a 175+ PF is pushing the upper limits of the brass. Im just guessing that you were using a P9 or EAA? They were wonderful guns, particularly as modified by Irvine or Barrette, but extractors and firing pins rarely seems to last a season. If you had the flexability of loading longer, like in the early Caspian hi-cap frames or Paras, the brass would tend to last longer. Then of course it begged the question, why 9x21 when .38 super worked just as well. (OK, the semi rim was a ##### in wide body mags :roll: )

I have not tried the large pistol/large rifle swap.


Please don't :shock: The large rifle primer is physically taller than it's pistol version. On top of the added pressure, you risk lighting them off on the press, or creating a slam fire on loading. If you swap pistol for rifle in the large size, you risk pierced primers, hangfires, gonorea, athletes ######, and worse.

Have no intention of doing so. Just following up on maynards post. Besides, I wouldn't want to get athlete's ######. :shock: :lol:
 
Canuck223,

Barette was using the P9 at that time. Mines were build on a EAA Witness competition frame with 5 3/4 inches barrel.
Why the 9X21 ?? A lot more reliable than the .38 Super. The 9 mm bullet were perfect for the 9X21 - .355.356 - the Super bore were often .356/.357. Some Super were shooting good with 9MM bullet , the other had to stay with .357 bullet..

The 9X21 OAL was longer than 9 MM Luger. Case are stronger - the best brass was Tanfoglio. That 2 MM longer did make a difference.

Today, the integral ramped -38 Super barrel are .355/356. , but if I get another open gun build, it will be in 9X23 on a STI slide-frame platform. :)

If the mags would accomodate the longer OAL, it was a great idea. If the mags limited you to plain old 9mm OAL, it wasn't much better.

I thought the 9x23 was a great idea at the time. Now I think I'd just go with the rimless .38 supercomp. It serves the same purpose and the chamber is the same as .38 super.
 
No problem with the OAL with CZ 9MM mags. This set up worked good enough to get me a Provincial championship.

Those are called racegun not for nothing. They have to be tuned, feed and maintained propertly to perform. The lowering of the power factor to 160 in the Open, make the 9X21 MM a safer alternative than 9 MM major. The 9X21 MM can make 160 with room to spare, and enough gases to make the comp effective.

9x23 is factory loaded by Winchester : mean brass for years to come..
 
i've tried small rifle primers (cci) in 9mm and a good portion of them didn't go off- just like duds- beretta 92 - trouble is you can't tell the differences just by looking- both priming mixes are yellow
 
rifle primers for pistol

If you take the 45 Long Colt example, you'll use the same loaded factory ammo for revolvere as you would for a rifle of this caliber. Primers recommended in reload manuals are large pistol primers for both revolvers and rifles.
