earlyriser,
Most of the people I know that have annealing equipment are BPS shooters that only load for themselves, not commercially. I don't know you at all, but I have no doubt you can do a satisfactory job of annealing your cases yourself. You can either use the cases in a pan of water/heat neck&shoulder/ tip case over method or you can put the torch on a table, twirl each case in the flame( holding it with your bare fingers) and drop it into a bucket of water under the flame. You don't need to heat the cases "red"( in fact, don't). You can't hold a case long enough with bare fingers to soften the head; whereas you can soften the heads, if you try to use an oven.
