Laurie,
I was throwing 28.5 grains of N133 or as close to that as I could get with my Harrell's BR powder dispenser, I think it was 52.3 clicks I found it not to be to consistent, what is your exact process for repeatable results, thanks in advance for your thoughts.

Wayne,
I didn't think a 0.5gn spread on 25 charges was exactly great! Assuming the measure design is basically sound, my only suggestions for what they're worth is to mount the measure on a solid stand (I use the Sinclair), 'knock' the body which my experiments showed does help a lot, and to operate the handle fairly slowly and smoothly. If the rotor cuts a kernel keep on applying steady pressure until it cuts through. If that causes a big jerk, then ditch that charge.
Alternatively, get a really good electronic dispenser / scales machine (for home use anyway). I'm steeling myself to impoverish myself a bit further with an RCBS Charge Master Combo. For BR, I much prefer to pre-weigh charges and take them to the range in stoppered glass vials. But .... we don't have to correct our charge weights here for big temperature variations. (Diggle Ranges are cold in winter and not much warmer in summer!)
Going back to the OP's question, I have a soft spot for the Hornady Bench Rest measure that uses a smaller dia. measuring thimble than the basic L-N-L model. I threw thousands of charges (to be weighed and adjusted) with mine before I got the Harrell's. I don't think the Harrell is any more accurate, but it is smoother which helps a lot, and the adjuster drum click settings where one click = roughly 0.1gn of stick powder is a godsend for all the load development I do, plus the ability to return to a known setting. (My reloading room walls are covered with Post-It notes that say 45.4gn Viht N165 = xx.x Harrell's drum setting and similar.)
I load 4,000-5,000 rifle cartridges each year and every charge is weighed, so life seems top consist of throwing and weighing charges at times!
