Free: Contests & Raffles.
This might be another Ford vs Chevy vs ........ , but I had the Hornady first and switched to the RCBS Chargemaster 1500. I've felt the RCBS was faster and more accurate at dispensing powder. I found on-line forums that suggested putting about an inch or so of a drinking straw or writing pen barrel in the discharge port with some powders, it did seem to increase the consistency of getting the exact weight. I have no Lyman experience, but IMO I'd pick the RCBS.
I've had my charge master since 2009. Had some issues with it for most of those years. Now I just don't turn it off and it is fine. If I turn it off most times it doesn't start back up. It counts down and then just sits at "OL" or "OF" on the screen. Thinking I may replace it this year
