.38 Special squibs

Why are people using mag primers that are more expensive when non mags do not require, some mag primers will have pressure spikes with some powders?

maybe things have changed but mag primers were always the same price as regular ones where i shopped. When lebaron was closing and there wasn't much left there was still a decent supply of mag primers so i grabbed a case.

Either things have changed or you live in a special place:

About 12% more expensive. A lot of retailers don't have any in stock.
 
FWIW, an interesting Shooting Times article on primers by a fellow who worked for CCI.

This bit corresponds with bigedp51's comments in Post #7:



And further to RocketSurgery's posta above (#36), I found this in an article on GunsAmerica.com:



OK- insomnia over for the night. Need to get some sleep :)

You realize by posting this, you also kept me up last night, lol

I've read a lot about people having issues with the Lee priming system on Pro1000/Loadmaster. I think the issue is that a lot of people take the instructions literally when they say you can be loading ammo in minutes. I think what Lee fails to mention is that it's a lot of minutes, like 180 of them, for you to completely tear down the press and reassemble everything. The main culprit is the primer feeding system which detects if a case is present on its way to station #2. When the press comes out of the box, you have to adjust the timing as well as the case indicator. You also have to tighten the shell holder to the ram.

You can't just order a progressive press and start pulling the handle, you need to learn how it works first. The guy I sold the Dillon press to was fully warned about the issues and said he's not worried because of the warranty. Well they won't send him a 4th press now, saying his gun is the problem lol.
 
My recollection of BULLSEYE SHOOTING with a .38 Spl wadcutter was - before firing each round, the shooter raised up the revolver about 60 degrees from level to assure the powder was banked up against the primer to assure proper ignition AND to prevent NASTY FLASHOVER explosion rather than "controled burning"...?
 
What primers? Powder? Use lube? Cleaning method?

I only use federal primers in my revolvers, Bullseye, no lube (Montana Gold jacketed bullet).
Heavy charge, light charge no matter within ten rounds I can garrantee a stuck bullet in the bore.
Gun always goes bang and factory ammo always works perfectly.
To be honest I have not tried a different projectile and the powder is fairly old (I have not used it elsewhere).
Not a gun I really use so I’ve relegated the problem to another day but if the OP finds a solve here you know I’ll try it out.
 
Ok I'm not new to reloading but I'm stumped.
I have a dillon sqdeal set up just for .38 special.Last month I reloaded 200 158 grn .38 semi wad cutters in tumbled 38 special brass using 4.4 grns of unique weighed on a Lyman digital scale for my S&W mod 14-3.
The first round fired fine then a squib,cleared that and fired 3 more rnds and a squib then 3 more squibs.
I tried 2 more cylinders of loads and had 4 more squibs.
SO I QUIT.went home and pulled the bullets checking the powder charges,they were all fine maybe a 10th of a grain either way.
The shots sounded like a pop and sizzle.
So last night I loaded up 100 rnds using 3.1 grains of bullseye
Shot today and the same results.
I'm using Winchester small magnum primers.
The powder is dry and new.
I just pulled 15 bullets and the charge is perfect
I also loaded 200 9mm rnds with another sqdeal and they worked perfect.
Any one else had similar issues

By elimination:
1-In the first batch, you had 7 squibs out of 18 rounds (3 cylinders), and all the rounds you pulled (that's a count of 182) had 4.4 +/-0.1 grn of powders. It means it's statistically impossible that you had 7 squibs out of 200 and got them all at random in the first 18 shots;
2-You tried another powder and had the same results, so it's near impossible that both bottles of powders were bad, especially if it's the powder you then used for the 9mm;
3-You don't talk about powder residues, so I'll suppose that all or most of the powder has burned. When it's not the case, the gun gets dirty AF, so you would probably have mentioned it;
4-A bad primer usually just doesn't go bang. Sometimes it's a slow fire instead of a no fire, but not for 7/18 rounds and then primers from the same batch working fine in the 9mm;

So what's left? I would tend to blame a combination of magnum primers with not enough crimp. The magnum primer is probably pushing the bullet out of the case before the powder is completely burned, so there never really is that much pressure being built in the case. The pop you hear is the primer and the sizzle is the gaz escaping between the cylinder and the forcing cone.

The reason revolvers do this but pistols mostly don't is that in a pistol barrel, the bullet hits the rifling and stops there, and the pressure can build behind it. Depending on the gun and bullet, sometimes the bullet will hit the rifling while still being in the case, but even if it's completely left, the pressure doesn't really have anywhere to go, so it keeps pushing the bullet. In a revolver, it can escape in the cylinder gap. So the same phenomenon will make for a crappy shot in a pistol and a stuck bullet in a revolver.

I would really switch to normal primers. I would tell you to crimp more but with lead bullets you can only crimp so much. You might wanna try new or 1Fired cases if your brass is old.

Excellent analysis, VinnyQC :)

I had neglected to re-read the OP's post and therefore that he had tried a different powder. And in my peregrinations around the internet in the wee hours last night I now remember reading that a (magnum) primer could dislodge the bullet, which could seriously reduce the power of the propellant charge to the equivalent of a "mouse fart" load, esp. with fairly light loads to begin with. Looking back, it was in the Shooting Times article I linked to. It didn't seem to apply exactly to the OP's situation so I omitted mentioning it, but it does appear to be a valid possibility in this case:

Too Much Primer

You can have too much primer. When the output gas volume of the primer approaches that of the cartridge case, sometimes special handling is required. I remember when CCI was working with some experimental primers for 9mm Luger, and we started seeing odd time-pressure curves on the computer. Instead of the normal single peak, we saw two. One QA tech commented that it looked like the dual humps of a Bactrian camel.

It was a classic case of high gas volume but too little temperature. The primer’s extra gas unseated the bullet while still trying to light off the main charge, producing one peak. Then the bullet retarded as it engaged the rifling, creating the second peak. Although a shooter would never notice this in a production firearm, that double hump was worrisome, and we abandoned that mix.

To mis-quote an old proverb, "Many brains make revolver work."
 
When you are loading your revolver, I'll bet you have the muzzle pointed down.
When the cartridges are loaded in the firearm, the powder moves to the front of the case behind the bullet. When the gun is brought up to shoot, there is a gap from the primer to powder. The primer is igniting reliably. Most likely the primer ignition is starting the bullet to travel and at the same time trying to ignite the powder that is also being pushed out the cylinder/barrel.
Try loading the firearm with the cartridges level and the powder at the primer.
I have had this problem in my .45 Colt; I had squibs on some shots and others I was finding unburnt Unique being blown out the barrel.

Absolutely. I load my 38spl with 5.75gr Unique. it's almost enough to spill over on a double charge, so it's easy to detect on the press if you've done it. I don't use the chain pull auto-disk system, I use the push-to-charge auto-disk set at 7.1 and the rounds show no signs at all of pressure, the primers are round and the casings are easy to extract. It's a nice combination with the light crimp I put in the cannelure.

In a revolver I would do not do this, the charge is too hot, and the Pro1000 cannot crimp well enough. I would try to find a 'bigger' powder than unique, I think it's called Trail Boss, not sure if it works in 38. I was taught that when you load your revolver, while it's aimed down, give it a wiggle once it's pointed horizontally. The thing I worry about most is the primer pushing the bullet into the forcing cone, and the powder just blowing out the side of the gun.

my pro1k crimps 38 or 357 plenty for max loads or heavy bullets, just need to adjust the die properly. trailboss works good in 38spl and everything else i've tried it in.
 
I'm going to try standard primers (which are hard to find here)
Loading and pointing the revolver up to shake the powder back to the primer is tough during a timed competion when speed is of the essence.
I just cleaned up all the standard primers the Cabalas had (a total of 300) and none on the horizon

Speed is less important than reliability

Well, at least you have some to try. Budget Shooter Supply has lots of CCI on hand but I'm not sure if they require special shipping.
 
It's a competition.I am trying to use my revolver rather than my semis.Speed is important and the reliability sucks.Im trying to figure this out with your guys help.

There will be a solution. I just re-read your initial post and realize that I have the very same model (14-3 is 1967 vintage.) I've not done nearly enough shooting with it but I don't recall any squibs. (I usually load 140 gr. HBWC over 231.) If the weather improves according to predictions I may get to the range next week. If so, I'll load up some 158 gr. SWC over 4.4 Unique with my usual Winchester SPP and see what happens.

Do you load with mixed brass? I find that if I get the crimp 'just perfect' for federal brass, it'll start crunching the thicker walled brass. This is why I just do a light crimp when I'm cranking out mixed range findings.

mixed ya, don't recall ever crushing a case in 38 but 95% of the time i load 148gr hbwc's.
 
Have you thought of phoning Dillion Tech Customer service and explaining to there tech representatives? They know their machines better than anyone on this site? They have darn good aftermarket service from my past experience.

x-reload, western metal and tenda have thousands of them available. Multiple brands too.
