One thing frequently misunderstood - - -
There is NO SUBSTITUTE for use of a reliable scale in handloading, since the advent of smokeless powder. The days of filling up a case and then shaking out just enough powder to allow seating the bullet are LONG GONE! That worked kinda, sorta, okay with some cartridges and black powder, way back when.
In modern loading, the use of a dipper or scoop is a substitute for a Powder Measure, NOT for the scale! Once you've worked up a good light-to-medium load, you can find or make a dipper that allows you to dump that amount into the case with minimum time expended. Actually, once you work out the proper uniform technique, this can be amazingly accurate. But one needs enough of a safety factor to allow for forgetting to strike the powder - - Using all the powder you can heap onto the dipper and still not being dangerous.
I'd personally dip charges for the .44 Mag which I KNEW were not much above a stout .44 Special level. And for .45 Colt which would probably be acceptable in a .45 ACP. And in .357 Mag - - Well, you get the idea.
I've seldom seen such unnimous expression about any topic in handloading, Rhinodogg. We ALL want to see you enjoy your reloading exerience, as safely as possible.
Best,
