Possible issues with Aguila SPP

[TTv2]

Doing the testing yesterday with my .32 revolvers, I was getting significant issues of primer cratering that was locking up the cylinder because the firing pin wasn't returning upon releasing the trigger. By far the worst was with wadcutters in .32 S&W Long (1.8gr of Titegroup, 2.1gr HP38, both with Speer wadcutters), but I did also get some problems with .32 H&R using these primers.

Here's the odd thing: the Taurus snub .327 didn't have any issues with cratering, it was only with the Ruger and Charter.

IDK what's going on. It could have been I didn't have the primers seated deep enough, I'm pretty sure I did tho. It could be these aren't good for revolvers, so I may relegate these to autoloaders. I do have some .38's loaded using these and I'll try them next week, but I've never had this issue before using my reloads in my revolvers. The only times I've had issues with cylinder locking up is when I shot .32 ACP and that's because of the rim being thinner and pressure forcing the case and primer back onto the pin and required my pulling out a knife to wedge the case off the pin, these just required whacked the gun with my palm to fix.

The positive things I can say is these primers went bang every time, they were about $.06 each, and don't waste space like Federal primers do.

What, no pictures?

I’ve never used their primers. Are they Federal soft?

 

[Soonerpesek]

If they all went bang on the first pull, then you could eliminate the possible seating problem.

Is there an option for a slightly stronger trigger return spring available ..?

Could be the loads are too light. Every time the firing pin hits the primer the first thing that happens before the primer ignites is that the round is pushed forward as far as possible. Once the primer goes off the primer actually backs out of the primer pocket due to the primer explosion. At this moment the round is pushed forward against the barrel and the primer is pushed rearward against the recoil shield. Once the powder ignites and the bullet starts moving, the case is slammed rearward with the same amount of pressure that is pushing the bullet forward. This reseats the primer in the case If the pressure is too low (light 32 wadcutter load) the primer does not get reseated. At this point the case and primer are basically wedged in the cylinder.

How tightly wedged the round is depends on many factors. This is why people recommend drilling out primer pockets for primer only loads. The primers will retain the firing pin impression more than normal due to the low pressure.

No issues with .38 in a Taurus, so it might just be that these primers don't like the pressures of full wadcutters seated flush with the case mouth.

My Taurus will only digest 80% of them in double action. In single action they're 100% though.
Federal and Remington 100% in double action so I can run those.
My S&W 14-3 runs only about 30% of them in double action and again 100% in single action.
Taurus M66 100% in double action.

Explain?

Yeah I would like to know about this as well. All the wadcutters I've loaded hated high pressure and are most happy running slow.

My Single Six .32 seems to have either an extra long firing pin or hits primers extra hard, as pierced primers were a regular occurrence for the first shots I fired.

I now use small rifle primers in this gun, 100% ignition and no more primer failures.

I wonder if the revolver firing pins in your Ruger and Charter guns are like the one I have?

Stay safe.

Have to see pictures, I did not check to see if you loads are remotely high pressure.

It is possible that the Taurus has a smaller firing pin hole than either the Ruger or Charter.

I had a S&W M686 no dash and primers flowed around the firing pin. Bound up the cylinder as I recall because the primer cup had flowed into the firing pin hole. Apparently that was systemic, owners complained, and S&W had to fix it. Later dash revisions had a smaller firing pin hole, which supported the primer cup better. Not all primer flow is due to "excessive" chamber pressure. Sometimes the dishing is due to insufficient cup support around the hole. Which is for that primer, is excessive pressure, especially if the firing can't release, or it binds the cylinder. But it is not excessive pressure for the cylinder.

Try a different primer than Aquila with the same loads, and see if that cures the problem.

Explain?

IDK how. .38 loaded to max +P (maybe even hotter) didn't have any of the issues I had using the same primers in .32 wadcutters using starting loads of Titegroup.

I've never had issues with the Ruger or Charter using non-Aguila primers. Federal and CCI never gave me these issues.

I used 5000 of Aguila SP primers a year ago did not have any problems with them. I used them in revolvers, 1911’s and my XD/XDM’s all went bang . They are softer like Federal and do seat slightly harder like other imported primers but I would not hesitate to use them again if the price was right. Calibers I used them in as follows: 9mm, 38 special , 38 Super, 40 S&W and 45 auto.

It sounds like pressure is low enough it's not repeating primers in the case. You may have other firing pin clearance issues. I live their horror with a savage bolt gun... I pondering bushing vs getting a grizzly bolt head... your options may be limited and a primer swap to one with no issues might be the cheaper easier route. Magtec are on sale everywhere right now might give those a try.... I'm running srp and spp right now.
