Re: New Brass, .243 Cracked neck
and on the flip side of the coin how do you learn a new skill if you never try.. Even if the cases fail the first few times, the firearm is designed to contain the failure provided you use safe loads.
Heres my method of cartridge case annealing, and Ive never had a case fail in about a half dozen years of case annealing..
3/8" high speed hand drill
Lee trimmer stud and lock nut for your cartridge
Propane or map gas torch
Small bucket of water
Chuck the Lee trimmer stud into your drill.
Take your cleaned rifle cases, and chuck them into the trimmer stud via the lock nut that comes with the LEE trim length gauge for that cartridge.
Set the torch on the floor in a propane bottle stand or similar secure method so it wont fall over.
Turn on the torch.
Spin the casemouth in the torch flame at the hottest point of the flame (google hottest part of a torch flame).
Watch the casemouth closely as it spins, the flame will begin to turn orange and a second or so later the casemouth will begin to turn dull red.
PULL IT as soon as you see the mouth begin to turn red and unchuck it from the lock stud and drop it into the bucket of water.
On to the next case..
The whole process takes about 4 seconds per case and the results are cases that are perfectly annealed at the neck.
This is an Art more than an Science, much like old time blacksmithing. I do not bother with tempilaq or fancy thermometers to see how hot im getting my brass. I can take .308 cases out of the lock stud with my fingers afterward.. Yes they are hot and will burn your fingers but not if you handle them quickly. Best to just loosen the lock stud and just shake them loose into the bucket. And for longer cartridges like .25-06 or .30-06 I dont use the water bucket. I just set them into the wooden load blocks to cool.
Best to dry the wet cases in the oven at 175 degrees for a couple hours.
It takes 43 muscles to frown, 17 to smile, and 3 for proper trigger squeeze.
The latest caliber or gear is no substitute for experience and skill. Rifles and cartridges don't make hits -- shooters do.
Fact of life:
After Monday and Tuesday, even the calendar says WTF!
