Annealing test

[muleman69]

Shooting buddy came over the other night and I was showing him what I don't no about annealing so we decided to do our own little test. We took once fired .30-06 RP and hornady .270 brass ,three pieces each. Fired up the butane burner on max and heated the RP trying to hold each piece at exact spot in the flame chucked in a drill at same speed. Held first piece 8 secs. second 9 secs. and third 10. Then proceeded to do the Hornady the same. After letting the brass cool completely off we took pliers and compared the spring back and softness of each piece and compared that to the spring back and softness of new Lapua Brass. After we each did the test we compared our notes and found the 8 second brass to be almost identical to the new Lapua.The 9sec. was a bit softer with less spring Back and the 10sec was quit soft no spring back. We tried one at 12sec for fun of it and it was toast soft and caved in with no spring. So the overall results of our backyard crued testing the 8 second won out and actually had a decent color as well. ( Been a Loooooong winter .......lol)

Good to know. Kind of funny but I use a metronome app. when I anneal. Most always find that times vary depending on brass and caliber. For my BR-based cases it's most always 8 seconds.

Cases like 30-30 can be as low as 4 sec. Depends on the brass.

I'm with you, I also tried some BR and got the same results. I'm planning on doing this caliber/brass specific to give me an Idea were to start

muleman69, many years ago the question came up about how a reloader would determine if a case needed to be annealed, and there was another question about the likelihood the case was getting to the point of splitting when fired.

It was about this time I found it is impossible to move the shoulder back with a die that has case body support.

Broken record!

I,m staying conpletly out of this one

I use a $15 PWM speed controller with a digital readout on my Anealeeze. It gives me a precise annealing time from annealing session to session. Once you determine the timing with Templaq for a case you can go back week after week and as long as the flame is adjusted the same you will get the same anneal. I don't claim it is the perfect anneal but it is consistent

Interesting idea,and cheap . Thanks for the link and idea,I will have to check into it.

I may catch hell for this, but here goes: In my opinion, the 8 second rule is out the door. I use the smallish propane bottles usually found at local hardware stores. My experience over several years showed some propane bottles produce different heat than others,thus varied times required to get the possitive results . I have used the same tip for all. Please don't F. Guffey me. Thank you.

I can't imagine the window being that tight with propane. Maybe MAP or other gas, but propane is just not that hot.

I always set my shoulder back a little when resizing. This is best done after annealing.

Reloaders in the old days did not require counseling and for the most part when asked they could give good rational for doing each task. I like the one I gave; I suggested the case requires annealing to reduce the cases ability to resist sizing. Today; reloaders grind the top of the shell holder or bottom of the die to increase the presses ability to overcome the cases ability to resist sizing.

Back in the old days I would use a feeler gage to raise the deck height of the shell holder, raising the shell holders' deck height increases the presses ability to overcome the cases ability to resist sizing.

Please tell us how you can squeeze a neck a .0005 with pliers, to check for a .0005 spring back?....... Jim

And the annealers march headlong into the Atlantic.

Strange, I have FL resized about 20,000 cases without even thinking about where the shoulder was. Never had a problem closing the bolt. Never annealed. It seems obvious that any off the shelf FL die will push the shoulder back and custom dies should also push the shoulder back. I got a shoulder gauge a year ago and it's possible to get way over 2 thou shoulder bump. I don't care what you think you can measure the facts prove otherwise!

I don't think the post mentions any 0.0005" movement or any measurement, just visual appearance of the amount of closure.

 

[johara1]

But what I stated is how you check them for proper annealing, you need to see .0005 spring back....... jim
