How to get 100% reliability?

[CWOOD]

I just started reloading. I just made up and fired my first 50 rounds.

While all of the rounds fired, 3 of the 50 required a second trigger reset and pull to do so. That is a 6% failure rate which would be unacceptable in factory ammo as I am loading to shoot IDPA (for now). Six misfires per 100 rounds would really mess up ones scores in a match. I have not had a problem with misfires in 1000s' of rounds of factory ammo so I am tending to rule out the pistol

Here is the equipment.

Glock 30

45ACP
1.265" OAL (same as Win. White Box)
Winchester LP primers
Wichester WST powder (4.1gr-4.9gr)
mixed cases all tumbled till shiny,
primer pockets cleaned
Precision Delta 230gr jacketed RN
loaded with Lee Classic Turret w/Lee Factory Crimp die
Primers fed with Lee Safety Prime

I checked by "feel" to make sure all primers were seated flush with or below head of case.

No goo on hands to contaminate and not really much contact with primers...maybe an occasional touch of finger to fully seat primer in primer arm of press...no other handling.

So how does one get 100% reliability?
What do YOU all consider acceptable reliability?

Any suggestions on how to improve this would be greatly appreciated.

Thanks

It sounds like the primers where not seated all the way or something prevented the striker on your gun from giving a full power impact to the primer. What method was used to set the primer? The hand tools work really well and you can feel the primer set.

Thanks for the input.

I was using the Lee Classic Turret.

I think you are correct that the primers were not properly seated. I just had it explained to me why that is so critical.

On to the next 50.

Thanks again.

If this gun has not had this problem with factory ammo it is definately a seating problem with the primer. One issue not already mentioned was whether or not the primer pocket was cleaned out before seating the new primers. Any crud in the pocket can prevent correct seating.

The pockets were cleaned. I tend to agree that I need to take more care to ensure that all primers are fully seated.
Thanks for the input everyone.

I'm assuming the "duds" had a light primer strike on the first attempt. Correct?

Given so, check case length carefully. Crimp amount could also be a factor. Too short a case or too much crimp could leave the round loose in the chamber so that the firing pin just pushes the round forward rather than driving into the primer.

Do you have a dial caliper? They are VERY useful for reloading. Plastic cheapees that go to 2 decimal places are easily found for not much money. I've used one for years.

Keep your chin up. Something is funky w/ these loads, we just have to find out what, fix it, and go forth. I've reloaded since ~1980 and have had ZERO misfires or issues with my loads; so you can make reliable handloads.

Good luck
