Has anyone ever seen this before?

X2 on the B's comment. I have used mag primers on 303 british, but worked up my load with those primers from the start. In some loading books I have seen other loads with the note to use mag primers for certain powders. I never tried mag primers with the BL(c)2 in my 7.62x54R as I was working with other powders at the same time and found H4350 was just way better and so have stuck with that.
 
I've had the same thing happen in 303 Brit with h335.

My cases were dry, no lube, and mag primers were used. Out of five round three went bang, one had hangfired, and the last was a primer pop and the powder ended up in the same state.

The powder was good as I used it for my 7.62 x 39 that day and at later dates.
 
Yeah, I know what that is... it's a "Licorice Allsort"... my grandad used to buy them by the bag when I was small. They're tasty, but give you gut-rot if you have too many in one sitting.
 
ya ok i had something similar happen with my .303 brit there were a few pieces of powder ledt in the cases after firing and they had gone yellow. So if i use magnum primers do i have to use less powder then im useing H4831
 
As someone new to reloading I would appreciate a definitive answer:

Is this a primer problem, powder contamination or just a picture of bird seed as one poster contributed.

If it is bird seed would a magnum primer work?
 
A magnum primer burns longer. It is handy for igniting slow powders. They have a heavy coating of deterrent. The ball powders are also harder to ignite.

If you use ball powder in ordinary sized cases, the Winchester Standard primer is an excellent choice. It is also a hotter primer.

I once loaded ball powder in 8 x 57 with a light bullet. Almost all of them were half second hang fires.
 
primer issue. NC propellant is actually very hard to ignite.

What primer are you using?

PS smell the powder, does it smell sweet or acidic?
 
Where did you read that? Certainly not in the reloading manual that you must have read..........

Nope, learnt that at a reloading workshop at my range... The guy was an expirenced 1000yd competition shooter so I respected his opinion....

What primer are you using?

CCI Large Rifle.

I'm not to sure if I want to fiddle around with Mag primers and what not so I'm just going to buy different powder. What's a good genaric pwder for 303 and most rifle cartridges?

I think you must have misunderstood what he said. Some people feel they get better accuracy with standard primers because with less flash they create a more uniform burn but that statement only applies if the powder is easy to ignite. If the powder is hard to ignite, you need more flash.

The colour of the powder is very similar to the unburnt powder granules I see left behind in shotgun barrels when I have used very low pressure loads. Your standard primers have enough oomph to push the bullet out and to compact the powder but not enough to ignite the powder

Clearly, you misunderstood what he said. It is not dangerous at all to use magnum primers in standard cases. It is done all the time, with standard load development techniques.

As well, there are many loads in loading manuals that show loads for standard cartridges using magnum primers.

D w A, here's what I found, about a year ago, when I dumped the powder from a 223 Ackley case that was a dud. If you look closely, you can see many yellow granules, as well as the clumped ones.

Same colour, but not all the powder was affected. Definitely an ignition problem. Powder was H335.

Don't give up! :) I would encourage you to try magnum primers in your loads. Either that or change to a stick-type powder such as 4895, 4320, 4350, etc.

But opinion it is. Not fact.
When I started reloading, I could only get magnum primers locally, so I used them in everything.
The only concern is that you need to back off from a max load about ten percent, and work up that load again.
You MAY find that it's ok for you to use the same max load. Then again, you may get pressure sign near the max end of the load. Magnum primers do make a difference.
It is only dangerous if you just substitute them for standard primers without working up.
 
I bought it from Elwood Epps so if it's bad powder I'm sure they'll take it back.

Unfortunately, due to federal regulations under the Explosives Act, Epps cannot accept returns on any powder or primers, regardless of condition or fault in the product.

There are signs clearly posted at the front cash check-out advising this.

If there is a problem with powder or primers, you must contact the manufacturer and request directions for product replacement.

I would say that it is an ignition problem. Primers can make very little noise when they fire in a dud shell. Possible you had a primer that was partially fouled and only put out part of its flame. Those yellowish or golden grains are typical of powder that has not completely burned.
