I was doing the math in my head. How many new cases could I buy for the cost of the machine? Obviously depends on the brand but let’s take 308 Lapua at 81 cents a piece (Midway). With an $1,100 purchase price of the machine the break even is roughly 1,350 rounds, or two years of shooting for me. Not exactly a precise comparison but gives you an idea of payback period. If nothing else gets the mind thinking about annealing process.
