Annealing plated brass?

I suspect that annealing nickel plated brass is not something that people do? - Likely due to the fact you wouldn't be able to see the colour change indicating when the appropriate temperature is reached? I am shooting a 7mm WSM and have issues with a significant percentage (Probably 15-20%) of necks splitting on the second firing. This is using once fired factory ammo, and below max powder loads. Mostly Federal, but I have some plated Win Brass as well. Have just started annealing the Federal brass so we'll see how that goes.

I dont do it but once read that when nickel is heated the plating starts to chip. And nickel is hard and abbrassive and the flecks of nickel are pushed down the barrel. I really dont know if this is true but i have seen it written on a few form online.
One other thing are you sure they are not steel i believe there are some nickel plated steel cases out there. I found some browning marked brass once that looked nickel but with a magnet it proved to be steel.

People can and do anneal nickel plated brass, and no one who knows what they are doing uses colour as a reference, so that is not a factor.
 
I've annealed F-C nickel plated brass for 7wsm using my AMP induction annealer. Also have done W-W nickel 308win & 300wm
 
Once had a batch of new Remington 30-06 nickle plated brass that I wanted to neck up to .35 whelen. The first couple i tried split the necks. so I stood them in water in a cake pan nearly as deep as the shoulder and heated them red hot with a propane torch, then tipped them in. All sized properly, trimmed OK, all shot OK, and I am still using that brass 3-4 loads and some years later. This doesn't mean I know what I was doing, but it worked once!
 
Thanks for the input.
For the record, I admit I dont know what I’m doing, so it really doesn’t need to be pointed out directly. That’s why I joined the forum; to learn more. So constructive input would be preferred.
Thanks TB, I will do some research on the AMP induction annealer.
