4064 isn't going to meter smoothly from any powder measure. All are alike in that they have a drum which must "shear" some grains as it rotates. That said, although 4064 will "grind" a bit as it goes through the meter, any good meter will drop it within reasonable tolerances.
The Redding is regarded as one of the better machines, but RCBS, Lyman and others are also dependable brands.

My RCBS might get it close, but it's not within my self-established tolerance. I've pretty much relegated myself to weighing each charge. As a matter of fact, I weigh most rifle charges anyway, with the exception of Benchmark for the .223. I like KNOWING what my charge is, not just hoping the measure got it "close 'nuf".

I use the Lee 'cheapo' measure. It works as well as any of them with coarse stick powders. One thing I have done though, is go to XMR 4064 (Accurate). I haven't noticed any difference in burn rate between the two and the XMR is a much finer 'grind' than IMR.
You'll have to go through about a pound of powder before the Lee measure gets all the bugs out. Then it starts throwing pretty accurate loads. I loaded twenty rounds of 7mm for my wife yeasterday. I was using 39 grains of XMR 4064 and, after setting the measure, no load varied by more than .2 grain.

I use a Redding and it will meter them all well, + or - a couple tenths at the worst and cuts the long grain stuff easily, the barrel is sharp as hell! The longer grain settling differently as it drops into the powder chamber in the measurer is what causes any inconsistancy, it's not the measurer itself. If it will cut the long grains easily, you will disturb the measurer alot less and settling will be more consistant... the Redding does this better than any I've used.
sealdoggy, check link below on this powder measure. maybe someone on this board might know more about them as i have never seen or handle one. it not suppose to cut the powder grains. anyway HTH Rick

I agree with all parts of this assessment. I think the Lee works better than the RCBS Uniflow for stick-type powders. But you do need to "condition" the Lee by running a pound or two of powder through it at first when it's new, before you try to get consistent powder throws from it.

I used to feel the same way, weighing all my charges. After all, if careful, you can weigh coarse-grained powders to within a single powder kernel! But recently I've switched to using the measure, mostly because I got tired of all the weighing. I use the Lee Perfect Powder Measure, even for supposedly hard-to-meter powders such as IMR4064 and IMR7828. The charges come out to within +/- 0.2 grain, and possibly better.
I haven't seen any decrease in accuracy or consistency of my loads, which is, after all, the point, isn't it?

I like the sh**ty Lee measure for stick powders. It levels the cup more like Mom leveling a cup of flour with the back of a knife in the kitchen...wipes it flush. Our old Belding and Mull we had years ago loaded us thousands of rounds with 4064. It had a spring-tension lever arm that gave pretty good leverage and feel for crunching kernels. Not a big deal, though we didn't like using the stuff for that reason. But, you are also not likely to find one of those measures very cheap. Never used the RCBS, but I didn't like 4064 in the Lyman measure. Any of them will work. The accuracy of the measurement is probably a lot more important for small capacity varmint cartridges.

I haven't tried the Lee. Maybe I will. But I have NEVER gotten particulary uniform loads of 4064 from any measure I have had. 4320 meters much better, as does 4895, and both are pretty close to 4064. However, ball powder is best, and WW 748 is right in there with those three IMR powders also.
I use a Saeco measure. The powder chamber is round like others so it must operate similar to the ones discussed here. While IMR 4064 may not measure quite as well as shorter stick powders even those with very short grains will be off when a grain is cut with my measure.
Taking RL 15 for example the measure yields about 0.4 grs more when a grain is cut.
I measure all rifle loads to just under the goal that are in ten piece lots or more and then finish it up in the scale with a trickler.
Since IMR 4064 has proven to be the most accurate powder with many loads for so long it should not be dismissed as being similar to other powders.
Perhaps weighing the charges does not improve the accuracy according to some scientific study but it makes me aim better. So there!
The measure on my Dillon RL550B works well with extruded (stick) powders, 4064 in particular. Ditto my Lee Perfect powder measure. My RCBS measure does not work worth beans for stick or flake powders. It does passably well with ball powders, but so does my Lee, so the RCBS never gets taken out of the closet any more.
Lee Dippers do a good job too, but I usually need to take two scoops for a rifle cartridge.
