Thread: Annealing

Not that this is a big help, look at cases that have been proffessionaly annealed and then look at your results when they cool down, does the colour band look the same?

Picture of cases overheated

The low temp Omegalaq (tempilaq alterative) was applied 2/3 the way up from the base to the start of the shoulder, the high temp was applied up the rest. No laq was applied inside the neck.

Spot on. Here is a photo of 308 ADI brass cooked to perfection. I changed my flame distance a tad so had to increase the time. They look like factory Lapua

Zimmer where do you get hold of your "templaque" form overseas? local engineering companies here just look at me weird here ....but thats usually the case with anything I ask

Got mine here Temperature Indicating Lacquers
They were good to deal with and no issues with exporting or receiving at this end that included the bottle of thinners (have yet to use) I ordered at the same time.
Their product is exactly the same as Tempilaq right down to almost matching bottle colour schemes. The devils.

Initially couldn't find anyone who would send Tempilaq from USA to NZ so went with Omega. Sincethen have seen Tempilaq on Brownells site IIRC and had heard of others sourcing from Amazon or Ebay cannot remember which.

As far a local sourcing the closest I got to something was from a plastics extrusion outfit in Auckland - totally the wrong temp and hugely expensive. Apparently their are crayons as well but other forums opinions don't recommend these.

Sorry about the thread hijack WillB

Heres some of my 308 cases done with the socket / drill bit count method, probably a bit on the low side for temp, as Zimmer says it can be a hit miss affair, so long as the flame / time is constant it is repeatable
I have turned them into 260 rem, havent found out how they shoot yet. Its been a bit of a muck around over christmas.
