I have an older Lock & Load AP so it’s a bit different but it has loaded thousands and thousands of rounds. Zero issues and would buy one again. I also have their Auto Charge powder measure and powder thrower with Micro-adjust both work well.
The electronic scales are sensitive to any air movements so sometimes you will get numbers to jump a tenth but I have never had that make any measurable difference.
My reloading is caveman style. New brass gets chamfered, lubed with Oneshot, primed, powder added and bullet seated to SAMMI coal or max magazine length and go shoot it. Used brass is sprayed with Oneshot cleaner/lube, rolled around on a rag, deprimed/sized, primed, powder added, bullet seated as above and shoot it.
I reload to shoot more and while I like reloading and developing new loads I don’t get sucked into the weeds with constant tinkering.
