primer powder help ?

[clintsfolly]

I loaded some 45 colts to shoot in my 454casull SRH a load of 2400 with a cast 255swc . i used WLP primers same as my 44mag (never a problem)but am having a problem now 2 out of 30 the primer fired but the powder never burnt. this has me baffled. what is your take on this? Clint [smilie=b:

clintsfolly:
Although I do use the WLP primers in my .41 mag loads, and have read that the WLP primers are good to go with the magnum loaded handgun loads, I would say that it is the primer, or the lack of. Meaning, that the load you used needed a bit more spark to set them off. The 44 mag and the 45 Colt use a lot more powder than the .41 does.
It could have been that there were a couple of bad primers, but there is not any real way of knowing that. All that being said, I would maybe test some more of the same primers.
If the same thing happens, switch to a hotter primer, CCI 350 mag or the Federal 155 mag. If they do the job, then you will know that the WLP primers were the culprit.

I'd be more suspicious of powder contamination, if you had a primer ignite but not the powder, given WLP. Those are set up to ignite ball powder so there is no reason it would not ignite 2400.

If you got neither a primer ignition nor powder burn ( did the bullet not leave the case? ), I would suspect poor seating of the primer.

2 boolits stuck in the barrel out of 30rds! Primer fired but failed to burn the powder. will get some mag primer and try again. Clint

sounds like there was no powder to burn
seems odd for a primer to light and not ignite the powder charge

Something is sure wrong, I use 2400 and WLP and they always fire fine and give good results over the chronograph and at the target. Your powder or primers may be contaminated somehow.Try new componets from a different sorce.

Years ago, I mean like 35 years ago, I was reloading my .41 magnum with CCI 350 primers.
For some reason, it escapes me now, I had loaded up some rounds with H110 and used the 300 primers. Well, guess what happened. Times up.
The boolits fell out the end of the barrel. The powder made the neatest little cylinder about the lenght of the powder charge. Imagine that.
From then on, I made sure I was setting things off with the correct primer.

the powder was there i had to clean it out of the gun !Clint

Classic lack of case tension on the boolit. The boolit is being blown out into the long throats before powder ignition, from the primer pressure.
OK, I am free to be hammered again! YOU DON'T need such a hot primer.

Clint, How much 2400 were you using?

[clintsfolly]

19.5 gr of 2400

[clintsfolly]

44man i think you may have hit the nail on the head!! both of the Duds have been in some used brass and the buddy that loaded them has had the same thing happen with h110 in his gun. Clint

19.5 gr of 2400

Seems to be generous plenty of 2400.

The only time I ever had the problem you describe is when I dropped some loads beyond 3% with some H-110 in a 32-20 with some condom bullets. Thin walled brass and no way to heavily crimp plus below recommended start caution. Yikes. Young and dumb. I solved the problem by switching to small rifle primers and VVN-110. Very accurate load in my Contender for hunters pistol taco hold.
