I've had a Pact for about 7 years and I am satisfied. Recently I was able to borrow a new DPS 1200 and do some speed comparisons. I thought that the Lyman would probably kick butt....I was surprised. I only timed large loads of around 90 grains H1000 and the two machines were consistently within 3 to 5 seconds of each other. The average time was 33 to 36 seconds for both...with the PACT winning about 40% of the time.
The Pact dumps powder faster and then takes more time during the final trickle stage. The Lyman chugs along a little slower but closes the gap at the end faster. Occasionally the Pact settles in at 1 grain under, but I can tap the spout or trickle. The Lyman was more consistent as to final charge weight...but not enough gain there to make me want to buy a newer machine. I hope to be comparing the RCBS soon...my conclusion..."The Pact is a little less consistent as to final weight but not much".
Also the calibration everybody's talking about is simply the machine cycling about 165 grains of powder to sync the dump rate for different powders....only takes a few minutes.
I dislike about the Lyman was the warm up cycle...now that is a real time killer in my opinion. 30-338
