Source for Tempilaq?

The only shooting seller I can see is spud, who has a £9.50 flat rate postage, which is frankly absurd for smaller items.

All other welding places I can see it online do not have online stores.

Anyone know where I can get, at a decent price, 750F tempilaq, for a fair price?

cheers

Forgot to add, look for Tempil on the Brands drop down.

I got mine from Omega, though with a bundle of other temperature stuff (barrel thermocouples etc) so I can't vouch for single item shipping prices.

Do you need the 750 version? I got both it and the white 475 (??) types from Walters & Walters when I started case-annealing (assume that's what you're wanting it for?), but found the green 750 one very hard to use inside the neck - ie judging when it was just melting and going back a fraction on the heating time. After a lot of searching online, I came across a very useful Youtube video from one of these pairs of Americans who spend their spare time putting these 10-minute video articles together and found a way of using the white one alone.

As well as a vertical stripe up from the extractor groove on the test case to ensure the case-head isn't being overheated, paint a horizontal ring on the top end of the case body around a quarter-inch below the body to shoulder junction and increase the heating period until it just melts. Using the green version inside the neck too confirms this is a correct setting ... or at least near correct as I think you can be.

The now withdrawn Hornady annealer with case-holding cups for use in an electric drill with a hand-held propane torch used the same timing-measurement system.

I do a similar thing, I use a band of 650f 1/4" below the case shoulder, this ensures the neck reaches 750f but the case head remains below 450f.

Thanks for the info.

I think the 450 should be good to go.

Presumably this method works on both .223 and .308 cases. is there any risk of overheating the neck to make it too soft with this method before the tempilaq below the shoulder melts?
