I have yet to hear what is too hot, and how is brass ruined, and what are the symptoms.
For those guys that say some temperature is too hot, how do you measure it since the templaq is not at the neck, but further down on the body.
How do you know it is ruined - do you use a hardness gauge and measure it... just exactly WHAT is too soft - and for what purpose - the benchrest guy doesn't need hardly any grip on the bullet, and many set their guns up so the neck barely holds the bullet, and the chamber/throat is used for the final seating... but the guy that loads a bunch of cartridges and throws them in his coat pocket for a season, needs much more "grip"...
.. so exactly WHAT are you talking about... in real numbers.
I have ~300 Remington 22-250 cases that have been through 5 barrels, and are now being prep'ed for the sixth - they have been annealed (until the neck was dark red hot) every 5 or 6 loads... and they have been loaded and fired about 45 times EACH.
So, since I have heated them to red hot, they must be ruined by some accounts - so when can I expect them to fail and go south???
I DO own a hardness gauge and I do own an infrared long distance thermometer - what are you guys using to make your decisions, since templaq is crude at best, and doesn't even read the site you are interested in.
It's unfortunate when the less knowledgeable new kids can't learn from old guys that have done this stuff for years and have already learned the pitfalls from doing it, instead of thinking they know it by reading about it.
