It is rare to receive anything nowadays that meets or exceeds the advertised performance criteria. The Burstfire Annealing Unit I received has performed flawlessly so far. I annealed about 1,600+ cases of various sizes: 22-250, 6-PPC, 30-BR, 6,5x47, 6.5x284, and 300 Ultramag. I am fortunate that I have access to a hardness tester. ALL of the brass I annealed is consistent, and 100% satisfactory. I fired about 250 rounds of various calibers, and find the results to be as expected. I believe the Burstfire will improve my average scores, and certainly make the reloading / brass prep operation more time effective. The only discrepancy I experienced was a single feeding jam with a 30-BR case. It happened only once out of four runs of 100 30-BR cases. I believe it was due to the short length of the 30-BR. I experienced no other problems whatsoever. I added a dial thermometer to the coolant tank. It has never gone above 97F. in rapid consecutive runs of 100 or so cases. I am 100% satisfied and pleased with my Burstfire annealer. Thank you, Burstfire.
