After watching Cortina's video, comparing the AMP with the Benchsource, I would like to see further testing to see if the AMP is really worth three times the money.
First, the spread between the seating pressures using his AMP press was only 4 PSI difference.
Second: If you used the same pieces of brass, and reversed the devices used for annealing, would the difference follow the brass? Another words, was the difference in seating pressures due to the brass itself and not the annealing process?
Third: Could you actually shoot the difference?
Watching the shots on the E-Target, while the AMP ammo shot a bit better, both batches of ammo had fliers. The AMP had them more horizontally where as the Benchsource was more vertical. That could very well be the cases themselves. Eric mentions that his bullets were not sorted so that provides another variable.
All the above said, I know that we like expensive jewellery. The AMP certainly fills that requirement. But the single loading of cases as well as triple the price, didn't show up dramatically on the actual shots fired. I don't think that Eric's test validated that the AMP was , hands down, the better annealing process.
I am in the market for an annealer, but based on Cortina's results, the jury is still out.
Question to those who have made the switch from flame to induction (AMP) process. Have you seen the average in your scores go up? That is really the method by which you should gauge the value of the AMP.
