use caution priming 10mm brass

[Cliff6]

I was priming some range pickup brass this morning and came across a Blazer 10mm case with a SMALL primer. I've never heard of this before. 45ACP yes, but not 10mm.

Maybe I've just missed it before, but I thought I'd mention it....just in case.

I did not know that any 10mm used spp thanks for the heads up.

10mm Short & Wimpy uses SPP

I found a bag of once fired 10mm brass at a gun show a few years and found out the hard way they had small primers.

 

[AK Hunter]

Was that a brass or nickel case?

 

[WestKentucky]

If I remember correctly the spp 10mm was pretty early and they changed to lpp for reliable and consistent ignition.

This was a Blazer brass case. I've loaded lots of 10mm, and they were always lpp, this spp threw me off.

 

[JO JO]

Yep they have both just like 45acp

 

[AK Hunter]

I ran into the same problem with reloading 7.62x39 cases.

 

[wankerjake]

Yes I’ve heard they are doing it but have yet to come across any yet

Probably NT loads (lead free non toxic)

 

[blarby]

They are from the blazer NT line.

I don't have a 10mm but I'll hold on to 10mm range pickup brass for a buddy who does. Never seen small primer 10, I'll pass it along.

Apparently lead free non-toxic pistol primers were intro'd in small pistol size.
So .45 ACP and .40 S&W for indoor range are made with small pistol NT primers.
I am not happy about it but I need to be aware.

Both the CCI/Federal lines standarized to SPP "nt" to prevent inadvertent placement of heavy metal primers in NT loads

Its a mechanical failsafe for the humes running the stacks.

Can you tell an NT primer from a toxic one?


Neither can the chutes. But this prevents that problem.

Believe it or not, primers are fed in huge assemblies in ammunition manufacturing at production levels, and even a few heavy metal primers in an NT production run can invalidate a testing run for federally procured ammo in the vent test.

Given that the vent test involves gauging all combustion gasses through a calibrated cartrtidge over 2,000 rds, its easy for a simple failure to invalidate an entire production run.

Its a neat system.

Small pistol primers are more than sufficient for all pistol loads, and the NT variant is plenty hot for all loads if you get em in trays.

You can prime these cases with standatd SPP, its just a manufacturing workaround for specialty rounds.

I haven’t run into any yet but will keep an eye out
