Cleaning new brass

[Bob3700]

Have had this happen to me twice now. First time, took new brass, sized it and loaded. At the range, experienced numerous misfires n hang fires. Disassembled the FF rounds n found the primers fired but powder was clumped together n did not light.
So, I washed the brass in soap n water to clean the internal case surfaces. No issues after that.

Now, second lot of brass, I wash it first before loading. Now same result, FF and hang fires. Powder clumped in the case. Guess I need to extend the washing cycle. Both situations were with new 223 brass.

Huh? What are you putting inside your new brass to make the powder clump?

I did not put anything into the new brass except powder. There is some contamination in the brass from the manufacturer. U need to wash the brass thoroughly to remove this “ oily” substance that effects the powder.

Who's the manufacturer?

I have Never heard of this???
If your powder is Clumped? Your brass is still wet, miss firing or Hang fire usually cause by weak primers for the charge weight. Or Wet Clumpy powder? And possibly flash holes not cleaned.

Initially, I did not wash the brass before loading. Just ran them thru my FL die n then loaded the brass as I normally would.
Now,all I have done is extensively tumbled the brass in dish soap n water. Takes a couple of hours in the wash n they now come out free of internal residue. Now they load n fire fine.
From the manufacturer, there is some contamination inside the brass that affects the powder. Primers fired but as they should, but powder clumped n didn’t burn.

Doesn't Starline put a note in their brass about cleaning it before loading? I've wet tumbled with pins their brass before loading and never had an issue. Both rifle and pistol.

I’ve mandreled and resized the necks and chamfered new brass, never cleaned any.

You could experience clumps of powder if the case is loaded to capacity or compressed for a while. As far as the misfires, never experienced them personally in new brass, not to say thing don't change with time.

Hang fires. I’d like a bit of clarification.
You heard the firing pin drop ( pulled the trigger) and what time period elapsed before the cartridge fired? A moment later? 2-3 seconds? Or it cooked off many seconds later?
FTF is one thing and happens for a whole variety of reasons. ( no powder, no primer, primer did not ignite, etc)
Hang fires are another world , of course it depends on your definition of a ‘hang fire'
Clarification needed.

My hang fires were Click —Boom. A delay of a couple microseconds. U could hear the click n then boom.

I also don't clean new brass and never had this happen.

Who's the manufacturer?

Yeah. . . it'd sure be nice to know what brand of brass does that. I guess he doesn't want to tell???

The only brass I've ever found with powder "sticking" was some Sig 277 Fury hybrid cases I recently got where some of the ball powder was sticking to the interior walls and necks of the case after power had been removed.

 

[Bob3700]

Had one lot of 223 and another of 6XC small primer Peterson brass.

I recently purchased a bunch of 6BR Peterson brass. They are tumbling in the soapy water as we speak. I did take a new cotton swab and run it thru the interior of the new 6 BR brass and really didn’t see any sort of oil or other contaminate.

Go figure.

No such note, at least in the bag of 223 Rem I purchased about a years ago,

I was thinking the note said to run a mandrel or expander ball through the neck to even up whatever they used on the forming process.

I have always F/L size new brass (no bump) using an expander ball.

In many cases, in many different brands of cases, I have observed necks that are dented from processing. In one brand of one lot I found the necks slightly off center. Another brand, the edge of the necks were not level, another brand, the new case would not fit a SAMMI case gauge.

Thus, I trim, chamfer, and F/L size all new cases to uniform them.

However, I have never experienced the condition the OP describes in 50+ years of reloading using various brands of new cases, i.e. Remington, Winchester, Hornady, Starline, Federal.
