sounds familiar. i like his work, but he needs to be more upfront to the customers about a realistic time frame for completion.
i am using a SP tuned Lyman M5. came from him working better, but after i followed advise from a well known contributor her on the forum to clean the knife edges and pivot point well and then burnish the knife edges with pencil lead, it took the scale to another level in sensitivity and repeat-ability.
when loading match ammo, i throw a charge from an RCBS manual thrower, trickle to the correct amount on the Lyman with an electric trickler, and then confirm the charge on a Grizzly Bald Eagle electronic scale. i keep another pan on the Grizzly and tare it each time before checking the charge on it. frankly, the Lyman is so good as configured, that i don't use the Grizzly when loading non match ammo. the Grizzly is just for piece of mind from a major screw up on my part
