I have yet buy a bullet puller... gonna have to now.

I reloaded cast bullet for the .30-.30. Plain based 170 grain fn bullet. Cast out of wheelweights. Used 9.5 grains of unique over CCI Large Rifle Primer. Primed on the press using Lee Priming Unit. Most did not fire. Those that did showed great accuracy.

Primers are from the same batch. They appear to be seated deep (can't get any deeper and they are below flush with the case head). Tried to reload the same cartridges multiple times without any luck. Normal indention on the primer when compared with the ones that did fire.

The rifle is a Marlin 336c .30-.30.

Only thing I can think of is to use my Lee Hand Primer to load them to see if priming on the press is my problem, but it hasn't been a problem in the past.

What could be causing the problem? (hoping RC answers since he has a plethora of expertise).
 
I just had my first CCI 200 not go off on me the other day.
Ive already used over 800 from the same lot without a hitch.
I had loaded up 21 rounds to do some velocity testing with my chronograph.
This was the first time in 1365 rounds fired in my 10BA that it went click when it should have gone bang. I really didnt like that sound.

Normally I use CCI BR-2 primers in that rifle but I wanted to compare the 2 primers.
 
If you squashed the primer in the pockets to much and damaged the pellets in the primers, they won't go off. Also if you are handling them with sweaty hands they can be contaminated to the point they won't go off either.

They should only be .004"-.006" below flush. If they are seated deaper than that then you stand a chance of damaging them.

I also know that when the last primer shortage hit there was a lot of complaining about quality control of primers due to a lot of duds. CCI was hit pretty hard by it but they were one of the only ones still supplying them. But I never heard of much more then just a dud here and there.

I would be leaning towards contamination or being damaged by seating them to deep.

Put up some pictures of them.

Just for curiousity you should try factory loads to make sure your firing pin isn't all gunked up inside or something.

Try putting a primer in at as close to flush but bit under and see if it goes off.

Don't put powder or bullets in the case, just the primer and shoot it in your rifle.

You can experiment with it that way to figure your problem out instead of having to pull bullets out of duds.
 
You got me, other then what tightgroup tiger already said.

Perhaps you just got a bad batch of primers.
Although I have used CCO primers almost since they have been in business, and never had a bad one yet.

I'd try using the hand primer, as squashing them with a press primer arm has caused me grief in the past, but only over-sensitivity in AR-15's, not misfires.

The other thing I might check is the rifle.

Your marlin uses two firing pins.
One long one in the bolt, (#25) and one short one in the locking bolt.(#26)

If one or the other is broken, it could dent the primer, but not actually hit it hard & fast enough to set it off.

And if you are setting the shoulders back too much on the 30-30, the issue could be headspace.
 
I appreciate all the help. I think I'll use the hand primer to prime 10 cases and load as usual and load 10 on the press with the same primers. I'll also load 10 with a new lot of primers on the press and 10 with a new lot of primers with the hand prime tool. Then I'll get a bullet puller and get busy.
 
I find a collet type bullet puller to be much preferrable to the inertial (hammer) type unless there isn't enough cylindrical portion of the bullet to grab.

Most of my bullets are cast and I would wonder if the collets would cause bullet deformity. of course, I could just remelt them down, but if I can save time on that step, I have time for more shooting :)
 
Homemade lube: beeswax, parrafin, petroleum jelly, and crayons for coloring. Ratio started out 1/3 of beeswax, 1/3 parrafin, 1/3 petroleum jelly, and a couple blue crayons. I didn't like the consistency and changed it here and there, but it' close to the same. Received the recipe off the castbullet forum.

Not hot at all. Loaded them up last night and shot them this morning when it was in the 70's.

I looked at the primers I'm currently using and they seem to be the one's I bought about 4 years ago. I will try my steps above to rule out a bad batch and/or bad seating technique.

I've never tried to pull cast bullets with a collet. They leave no marks on all of the jacketed bullets I've pulled. They are caliber specific (obviously) so they are more spendy than a bludgeon-them-out puller. A lot quieter also.

I do a lot of load development on my four 30 caliber rifles and the collet puller is essential for disassembling loads that don't work like I want them to without damaging the bullets.

That right there could be your problem.

The Vaseline may be migrating to the primers and killing them or the small charge of Unique if they set unfired in hot weather.

You need to pull some that didn't fire, and see if it was the primer or the powder that didn't light off.

I'll do that. Any advice for a good substitute for the petroleum jelly? I like making my own versus buying so that I can be self reliant.
 
The NRA recipe is 50/50 Beeswax/Alox.
It don't get no better then that.
You could add some crayon for color if that trips your trigger I suppose.

But I'd leave the Vaseline for chapped nether regions if I was you.
It melts in hot weather and can kill powder & primers if it seeps into them.

I had a recent failure to fire with a handload. One edge of the primer cup folded up inside the primer when I seated it. This powdered the pellet. loaded round looked just like all the rest of the fired and unfired cases. I was able to pull the bullet and punch out the primer to inspect the dud.

I would definately waste 20 primers in unloaded shells to prove or disprove the primers concerns first.

$0.60 of primers may speak volumes about this.

If they all fire then you elliminated primer, and press issues, and can move on to the lube.

Unless your bullet lube is half liquid I wouldn't think it could creep from the bullet to the primer, just over night. Unless you had it on your fingers and handled the primers at the same time.
That seems unlikely also since you really don't have to handle primers with the Lee hand primer I'm thinking of.

I would definately change your lube recipe like RC said.
 
If the primers would have gone off, chances are the bullets would have come out,crimped cases may stop it, but I find it hard to believe that it would be lube. I use it also, many recipes use ingredients(olive oil, stp,trans fluid,parafin,red grease,on and on) that can stop powder from igniting but there isn't enough lube in the grooves to contaminate ALL the powder, so some would likely ignite.My guess anyways
 
I had some cci primers that would no go bang and guys said it was because of the encore not having a strong enough hammer strike and cci are hard they recommended federal and haven't had a problem since my guide gun shoots cci fine but may wanna try a softer primer just incase
 
has any one worked the trigger on you 336?

cutting a loop off of each end of the main spring is a common "trigger job" mod on these rifles.

It can leave you with a week hammer strike, however... and dented, but not ignited primers.
 
Not that I know of, but it was purchased used from my LGS. If these cheaper ideas don't work, I might take it to someone of more knowledge than me to rule that out.

Note: Works great with factory ammo, so that leaves me thinking that I am the problem.
