Re: What powder system do you recommend?
If you have a manual meter that throws within a 1/10th you've got a damn winner. I have or have had all the meter mentioned, and two things about them all. First, the Lee is really pretty accurate, which is counterintuitive as it is a cheap little thing. I don't like it for just that reason, and HELL no I never had it consistently throw within a 1/10th. I still have the Harrels Premium Culver, just beacuse it is such a nice precision tool, but it won't throw consitently within a 1/10th either, but close as anything I have used. The Redding is a good piece, and I had mine until just recently when I gifted it to a buddy starting into shooting and reloading. It was close to the Harrel, not quite as good day in day out, but damn good, and NO, not within a 1/10th consistently.
I had a glitch with my Chargemaster just today, but I got it back up and running, and it has been flawless til today, for several years. It is a better mousetrap IMO, and I have the LABORATORY grade scales to check all this data. If you want a manual measure, the Redding will serve you well, if you are looking to save $ the Lee Perfect is darn hard to beat. Dumping into a pan and trickling charges up is pretty slow to me, and I load too many rounds to do that---whether you need to weigh them all or not is a whole other argument--a lot of old school folks will tell you it's about VOLUME, not weight--and so if you are in that camp, a regular old powder measure is all you need! I will say that when I set up my Harrel and throw charges that I am not that peculiar about, I can go faster by about 2.5 to 1 over my chargemaster on charges in the 50 to 60 grain range.
With Varget, which I usually run around 45 grains, the time difference is less, but still I can usually 'dump' 2 loads to one with a 'thrower' vs the Chargemaster.
Good luck!
