Annealing made perfect

[jimmymac]

Truth be known, I don't shoot matches. If I did it would be easy peasy to have 100 pieces of brass annealed and ready to be loaded at the match

I understand how simple the procedure is. That's not why I asked the question. I asked because at a match, guys reload on the spot. They may use the same 20 or 25 pieces of brass over the course of a two gun competition. That brass will get reloaded several times during the course of the competition, so I just don't see annealing in this instance as being practical.

So what say the SR group guys that compete. Do you ever anneal either at the range, at home or in the evening when the event takes more than a day to complete?

Come on Lou. You started this thread. I know you shoot short range group. I'm trying to figure out if you anneal for that discipline as well as the other disciplines that you shoot.

Thanks

I have seen more brass ruined ,along with scores, than improved by misunderstood annealing process.

SR group?

DT was discussing thickness of the RIM, Not the shoulder, and He's correct.

Well, sort of. If I were designing it (and those guys are probably way smarter than me), I would have taken readings from the thousands of various cases I have on rim thickness and take into account the average variation when defining the limits of my sorting algorithm. In this case, I've accounted for natural variation - backing the pilot out .001" would cause the case to fall outside that natural distribution and therefore, register outside the acceptable range.

Just a guess on my part, given the advent of the AMP annealer and it's ease of use and speed, if annealing does make a difference for the SR group, they will use it at matches.

Long YOUTUBE video but might be worth watching if you are interested in the AMP

Jimmy there are guys that do anneal after each yardage and rotate 50 pcs of brass so it amounts to after every firing. Most do not because as you are saying they are on a fold up portable bench under the loading shed
Some of the guys in the motor homes and campers are annealing
I started testing an AMP a week ago I have to say it looks promising. I annealed an old set of PPC cases primer pockets are a little loose probably 75x fired practice brass. They shot some really nice groups. What I don't know is if they will hold up 1x 2x or more before the groups open back up
Most that travel to competitions start with a new set of cases 2x fired or so because they give more consistent neck tension than after 25x or so firing
I'll report more next week.
Still if you Miss a flag it doesn't matter if they are annealed or not

Thank you Tim.

I believe what the new Aztec software does is measure the mass of actual brass inside the inductive flux region. They know the energy going into the test piece and the current flowing in the effective single turn of a shorted secondary winding (the actual case neck and part of shoulder). By now they have accumulated thousands of data points on case dimensions and styles vs energy vs time data points so they can now empirically calculate the power level (by adjusting the flux gap dimensions) and anneal time needed for a given case. Check their patent, they have an adjustable flux concentrator and adjustable power as well as adjustable time. Of course, predicated on using the appropriate case holder to insure the neck and shoulder are positioned correctly. Not really rocket science, just good knowledge of the technology and common sense!

FINALLY!!! Since Emmett Brown came up with the idea in 1955, and again since it's (very brief) usage in 1985 once the technology became available to actually BUILD the thing....... this is the next best usage for the vaunted flux capacitor.

A great step forward indeed!

Rich, thanks' for the video...can't wait for the Aztec!

Talked to Alex and he says Aztec should available mid-March.

I was cruising the board and saw this thread. I was at SHOT and shot this video on the AMP Aztec feature. It's quick and to the point. Not a long video at all.
