Slivers of metal when crimping

Post by Morne »

Just made another batch of .38 specials using copper plated bullets. I seated these a little further into the cannelure than I showed in my other thread. I also crimped them a bit more, but they still fit fine in my cylinder.

What was odd was that after crimping I found slivers of copper. I presume it is from the plating rather than from the casing. Anybody else experience this? Is it possible to over crimp a little bit and cut plating but not enough to cause fit issues?

Yeah, plated bullets are very very thin. Crimps sometimes slice a bit off. Doesn't seem to affect performance.

The little shavings usuy happen when you crimp and seat in the same step .
It can also shave if you dont flare the case enough an or forget to chamfer the mouth

If you have flared and chamfered here is why it shaves
The seater is still shoving the bullet down when it starts to crimp .
Most times you can fiddle with the die and stop this it usualy only takes a very minor amount of adjusting .

Start by backing the die out about 1/16 of a turn and readjusting tje seat stem .
Just move it in small amounts untill you find the sweet spot where you get the crimp you want
And it doesnt shave .

Or you can do as i do and seat / crimp in seperate operations

If you plan on shooting a whole bunch of the same load it is usualy worth the time
To fiddle with the die .
Or if you are like me .. shoot a bunch of differant loads/bullets
Its usualy faster to just keep seat / crimp in seperate steps

I have enough little slivers that it looks like I'm running the key cutting machine at the hardware store. I was under the impression that my slivers are all from the case mouths rather than my plated bullets, but I suppose it could be either or both. I have no concern for it -- my brass life is fantastic and my loads are BETTER than that! 8)
I like to swap brass... and I'm looking for .32 H&R Mag, .327 Fed Mag, .380 Auto and 10mm. If you have some and would like to swap for something else, send me a note!
