AMP MKII brass codes and ?

[sveltri]

I know the easiest/right thing to do is Aztec a piece and just be done but my OCD hates seeing that missing brass in the ammo box. Is anyone willing to share codes for different cartridges and lot #’s? How much variation have you seen lot to lot for Lapua 6.5 CM or Lapua brass in general in terms of AMP codes?

Lapua puts 101 in the box so you can burn one.

Peterson posts codes per lot.

 

[waspocrew]

just so it’s out there - alpha gives you the amp codes as well.

They used to, when they switched to the cardboard boxes the qty became 100.

Dang, really? That was always nice to have the extra.

I Aztec’d my first piece of Lapua last week and it hurt to do it lol. But I wanted the best reading from my machine to get it right. Plus I anneal as first step before any cleaning and figure the codes it give may be different then if it’s done say after cleaning possibly.

I just wanted piece of mind knowing the code was perfect for my lots of brass in the condition I’ll always be annealing so I did the sacrifice.

I try to get a sample of three from new virgin brass and then use the average. On 1x fired factory loaded brass I double that . I don't bother "burning" Peterson anymore since it's so consistent and the factory provided AMP code matches my tests as well.
Either way, here are two lots of Lapua, hope it helps.

When I Aztec’ed two once fired Lapua 6.5 PRC’s I got 0194.

I test mine after wet tumbling. Were yours clean or dirty? Not sure if that matters. Also, I use all the correct pilots for each cartridge. There could just be variation in the induction element for each unit.

I got much higher AZTEC codes from Lapua brass fired from Berger ammo vs Lapua brass bought for reloading.

I just Aztec'd a 6.5 Creed Hornady case - 0140

That’s about right. AMP recommends obtaining the AZTEC code from once fired brass. It will differ slightly from virgin brass.

They were wet tumbled/clean. Purchased as reloading brass (not loaded ammo) and using the correct pilot (#20 if memory serves).

What do the numbers mean in the code. Are they an arbitrary number or do they represent time in some manner?

Yes it’s a time factor I believe.
