I love their testing and analysis. Pretty good detail and information. The salt bath results were the biggest surprise to me. I had always been led to believe that most factory annealing was by salt bath and this proves that is ineffective for bottle neck cases.

The test I liked most was the one case tunnel shooting comparison of anneal and not. Each case fired 20 times into same target. No anneal and 0.5" groups were shrunk to 0.3" with anneal.

I would like someone to compare bushing die vs collet die to see if the annealing has different effects. Was also interesting to see the difference of annealing after sizing vs before. The other surprise was how well powder fouling in the neck was for lubricating vs conventional neck lube. I knew it worked well, just didn't know how well. And, I thought the flame annealing would negate the fouling benefit.
