AMP settings survey

[SteveOak]

Sometimes I wonder about stuff. Data gives me something to cogitate on so I am asking for data.

What setting are you using or have used in the past for your brass when annealing with an AMP annealer?

Please state cartridge (6 BR and 6mm derivitives of the BR only please), brand of brass (gold or blue box for Lapua) and neck thickness along with the AMP setting you are using, whether or not it was determined by Aztec and if so, the Aztec code you used.

Feel free to include any other specifics of the brass/cartridge you think may be useful and any observation, thoughts, questions, etc. germain to the topic.

Please also share observations about the results such a springback, neck tension, method of neck sizing or expanding, case longevity, basically anything relating to annealing with an AMP annealer using the Aztec program and results thereof.

I will attempt to organize the information into a spreadsheet.

6MM Dasher turned necks .0104, Lapua Blue Box Brass, Aztec code: .0135.
Don't know how long the Brass will last, I have some that have 22 firings on them
and they still feel like knew, primer pockets still tight and neck tensions are very consistent.
Chamber = .267 Nk.
6MM Bra, turned necks to .0104, Lapua Gold Box Brass, Aztec code .0141. 200 rounds fired, 5 times
still like new. Chamber has same neck diameter as the Dasher neck tensions also very consistent.

6BRA fireformed Lapua 6BR Norma brass necks turned to 0.011"
virgin case after turning AMP Aztec case burned....code 144
same batch of brass after five firings code 146*
same batch of brass after twelve firings code 149*

* I do not clean inside my necks/brass....outside only to let the carbon build up inside necks

I would not have expected that much differance.
