Hi Brent...
I have 3 Redding BR measures - a BR-3, a BR-30, and one of the new BR-10X measures. They have worked well for me, and when I was having an "anal" moment for match ammo, I would use a trickler to be right on (mostly for my Rem 6BR).
I had wanted a Culver measure for a long time... I guess cuz they're so **** pretty, and everyone says that they are more accurate.
... but my best friend just got a Culver (he also has several other measures), and he said that while it's very nice, it throws with the same errors as the Reddings.
The thing about the Culver is that the calibrations in the dial are accurate with ALL other culvers, and people that use these measures refer to their loads, not in grains, but in Culver "Clicks"... so when one guys asks what load are you using, the other guy says "16.5 of H322", meaning that he is using a Culver set at 16.5 and throwing H322.
Well... that's very nice, and shows a dedication by Mr. Culver to mechanical repeatability... but it DOESN'T help with throwing Varget or H4350-SC.
My friend also has a Niel Jones, and said that it's was very superior to the Culver, and looking at the two, I would have to agree, the Neil Jones is a WAY better measure... but at $375 each, it **** well ought to be!!!
But the jist of this post is that all of these rotating drum measures suffer the same problems, and all the needle bearings in the world is NOT going to help.
The problem is not the measures, it's the powders... from a rotating drum measure, you will get +/- 0.1grain, or more in errors, and often it's closer to +/-0.2 gr errors., which means a 0.4 gr spread
The spread on the measure of my Dillon 1000 (set up for .308 Match) is about 0.3 gr wide (+/-0.15), and I think that's about as good as it gets.
That's because of the powder, not the measure... you can't get stick powder to fill a chamber (ANY chamber) the same way, each time, with a powder that is made of long sticks. It refuses to settle the same way each time. The stuff is like pick-up sticks
I wish ball powder wasn't so temperature sensitive (or so dirty), but until there is a better ball powder, I'd rather deal with the slightly increased SD with Extream stick, than have to deal with the wide velocity changes of ball... and I'm not gonna weigh 10,000 charges a year
