I had issues with the annealeez when dealing with dasher and br brass. I only got one reply from Annealeez and after that he stopped responding to emails or issues.
I had the smaller br wheels but after a few cases they would start melting and leaving plastic residue on cases which was a pain to remove. I put some foil in the opening for the case and it help a bit but in the end it was best to only do 50 cases at a time.
My other issue was inconsistent annealing of my 284 cases and I traced it to the wheel not spinning the cases. When I setup the annealer without the flame, all the cases were spinning. As soon as I applied the flame it would stop spinning cases after about 5 or 6 cases. I tried several things and I even applied a fresh coating of the blue gasket material that is included on the wheels. Nothing seemed to work.
I finally got tired of the minor issues with this annealer and sold it. I started with a benchsource, then AMP Gen 1, Gen 2, annealeez and finally the Ugly Annealer. Having tested all these units, I’ve come to the conclusion after testing at 1000 yards that if you get the brass hot enough for good annealing in the neck/shoulder junction that’s all you need. I have achieved consistent resizing, brass life, excellent chrono numbers and most importantly great performance on target. After owning several annealers I also know that I do not need to spend over $300 to achieve good annealing and performance on target.
The ugly annealer seems to be very well built, No plastic wheels, easy to setup, consistent, handles several pieces of brass, small foot print, no need for extra wheels or pilots and it includes everything in the box to handle all the calibers I shoot. For the price this unit cannot be beat:
