I do not own or use the AMP but you may want to read the article below before you try salt bath annealingAs long as you only do salt bath annealing. All the others are just fancy stuffs guys use to get strippers naked. Or is it bath salt annealing? IDK but the AMP with the thingy on top looks titties to me.
The real question is... did both of those things equally increase consistency or did you just start both at the same time and got results?Yes.. I have just stared annealing this year and have been able to get a more consistent neck tension with that and the use of expander mandrels together.
My ES/SD have dropped to the single digits and my reloads are consonantly producing better groups, if I do my part.
Now I am intrigued. What is a straight-taper case?I'll echo the majority here and say no, definitely non-essential. But I will say that once i started playing around with the big, straight-taper cases and the weird issues i was getting with inconsistent shoulder bump and neck tension, I was annealing every firing and got 117% fed up with the blow torch and drill/socket. I bought an annealeez to automate the process, and boy it sure is nice. You do have to babysit it, but it beats the the shit out the drill and socket.

Hey... It was late... and the sun was in my eyes. What i meant to say was low body taper.I was gonna say he meant straight wall but then he mentions the shoulder.. so I have no idea lol. Im curious too now.
