I'm going to get run out of town by an angry mob again just for suggesting it, but here it goes-
A RCBS powder dropper is more than accurate enough if you know how to use it. First of all you need a baffle for it- why they sell these things without a baffle is beyond me. What the baffle does is allow about an inch or so of uncompressed powder to sit over the top of the measuring cylinder. If you have a full column of powder above the cylinder without a baffle, the powder tends to orientate the grains in a different direction than loose powder, and having the extra pressure on the measuring cylinder will give you inconsistant throws as well as alot of cut grains (they don't matter, but makes for difficult operation).

Bottom line is don't give up on the powder thrower- get a baffle if you don't have one and practice with it.

With the baffle in place, you just need to keep the powder topped off to roughly the same level and to throw your charges consistantly- I use a sharplift on the handle, then let it lower on its own weight, lifting the handle about 1/4 back up and allowing it to bounce on its way down again. I do it the same way every time. When I top off the funnel every 15 or so charges, then throw 3 or 4 charges back into the powder can to allow the charger to equilibriate.

What I would do is sit down for an evening and practice your powder throwing technique- there is no reason why a thrower shouldn't be able to do +-.25 gr, I do it consistantly with IMR 4064.

Here's the part where people will want to run me out of town about- you will be very unlikely to get better accuracy by weighing each charge- been there, done that, got the t-shirt to prove it. 1/2 gr doesn't make any difference in rifle cartridges unless you are loading up to the very edge of 'high pressure land' where you aren't loading for accuracy anyhow, but should weigh your loads for safety. If you throw the powder consistantly, you will have equal volumes of powder in each case, which is more important than precise weights- a cartridge case doesn't know how much powder weight it contains, but the amount of space filled inside the case is important.
