Miss Fires in a 45-70

I'm still thinking cotaminated powder.

Is that spray lube the one from Lyman? If it is the Lyman stuff you must use extra care to make sure all of the lube is off and OUT of the case. It WILL ruin the powder charge.
Not Just pickin on Lyman. There are other lubes tha behave the same way.
I have had a similar experiance when loadind 223 and using Lyman spray lube. new powder good taper crimp and fizzle. turned out to be case lube in the case.

Bushmaster. His mother is the 22 issue. Though she use to go bow hunting with me. We were on a stand south of Tallahassee, when I grabbed her head and twisted it just as a mother and her cub stood. So I don't know what her issue is. Besides Dillion are pretty easy to use once set up.

1895Ss The bullet is a 305 grain jacketed. And no did not use any crimp at all.
Will try to crimp some and see what happens tomorrow.

The best crimp I have found is with the Lee Factory Crimp Die. You can adjust the amount of crimp and it crimps the same even if your cartridges are not all exactly the same length. Smile

OK Badshot, that's a little better. I'm glad to know you have loading experience. That makes it easier to address as you know most of the lingo. I'm still puzzeled though as I don't crimp my 45-70 loads much. I've used CCI 200 primers with IMR4198 @ 38 grns for a 350 grn Jacketed flat point or 55 grns of Varget pushing a 300 grn cast lead flat point.
Keep it coming...

Gidday Badshot.

I'm not familiar with the Lyman Spray Lube so I won't comment on it. I use Pacific lube. Its a honey coloured very thick sticky liquid. Had a little bottle (about 2 - 3 oz) for the last 20 + years and still have nearly half left. This stuff is pretty good. Whichever lube you use I believe you must clean your cases thoroughly after sizing to remove any traces of the lube. I use CRC Brakleen, very volatile, but cleans oil etc off really well and dries within minutes without using water. This avoids any contamination problems and also stops crap and corruption sticking to your loaded rounds which can mark your chamber.

Reference your grandson.....I know how you feel. I have two grandsons who live in a great pig hunting region over here in Australia and they are always asking me to bring a rifle with me when I visit. My daughter (their Mum) refuses point blank to allow them to have any contact with guns because she does not like them. In fact a pig hunt I was planning on next month may now not go ahead because she won't let me have a gun in her house so I am not allowed to take one with me! @*%^# Mad

Keep us tabbed on how your problem is resolving....its very interesting.

Cheers, Vince

If you are having problems with the 3031 try another powder. There are many good powders out there that may be very well more suited toward your low pressure loads. I would try some Accurate 5744, they have a 300gr Cowboy load with a max of 31gr and 18,500 psi. check link.

5744 does need a good firm crimp to be consistant. Cool

Something that comes to mind.......as they sat, where they exposed to high humidity? When you say sat, I assume you mean the primed cases sat for 2 weeks. The primers could have soaked up enough humidity to dampen the spark? Just a thought.

Blaine I'm just asking & no argument intended.
I know it was just a thought and I'm wondering why you are thinking this but what would be the diff if the primers where in the paper carton or the brass at the same reloading bench as far as soaking up humidity? Smile

I have had primed cases sitting there for months and never had a problem but then again I may not have as much humidity as some of you folks south of here. I am wondering if anyone has had this problem before........? Smile

It was just a thought on my part. The primers sitting in their containers are surrounded by at least 2 layers of absorbent cardboard material, whereas the primers in the cases facing up to the air....I don't know. As I say, it was just a thought. Whenever I prime cases, I always finish the load immediately so that the primers won't be left out in the open air. I load in my basement, and I'm always worried about humidity. I store my primers in a 50mm can sealed to the air. You might be right....it may not be a problem.

I have some pictures now.

I'm thinking now crimping will resolve the problem.

I should have mentioned the damaged bullet is from knocking the bullet out of the barrel.

Good answer. Almost thought you might be trying to shoot a rifle chambered for .45-70 but the barrel had not been changed to .45 L O L.

That looks very odd. Shocked

After viewing your picture I'll bet you are having a powder problem! If your primers have enough oomphhh to push your bullets into the rifling and you have to hit them out you are definately not having a problem with your primers!! The way that your powder is formed into a column and not falling apart leads me to believe that your powder has been greatly contaminated. Take the remainder of that powder and sprinkle it on your lawn, it appears that the only thing that it is good for at this point is fertlizer. Get some new powder and try er again, I highly recommend the AA5744 for low pressure loads in a Trapdoor. Best Wishes and Happy Shootin. Cool
