this may sound stupid but how well will a RCBS uniflow throw charges of IMR 4350. my brother gave me a brand new Uniflow. All I have ever used was a chargemaster 1500 but it is his and I am assembling my own stuff and don't want to fork over the doe for a chargemaster right now, so I was going to use the messurer but I herd they don't work that well with stick powders. input from the experts?
 
I have a Uniflow and it will work with coarse stick powders like 4350. It's not as smooth to use as it is with a ball powder is and not quite as accurate either though. I usually just adjust the powder thrower to be just under the charge weight that I want, then top it up with a powder trickler for the exact weight.
 
Accuracy is not to important as I wil be trickling every load anyways. I was more interested if ity would meter at all. if the sticks break do they burn any different?

4350 and other similar coarse powders will meter through the Uniflow, but just not as consistent as a finer powder. With a ball powder, the Uniflow measures exactly the right charge weight ever time. With a coarser powder, it might be a little high or a little low, but it's close. I can't see enough of the granules breaking to make any difference whatsoever in burn rate. If you use your trickler every time, you should like your Uniflow. It's been on the market for a long time.
 
I find Hodgkins 4350 much better in my powder measure than IMR 4350.

Grains seem to be shorter and it throws much more accurate loads.
 
I always make sure when I throw the charge I snap the handle with a quick solid motion this will cut off some of those stick type powder grains that seem to try and hang up the throw. I always under charge and then trickle to finish.

That`s probably the number 1 thing I like about my ChargeMaster Combo. No more powder `crunching`:mad: and weight fluctuations with the coarse grained powders. I used to use a set of plastic spoons as a powder scoop & trickler to measure out each charge.:D

If you do not intend to weigh every throw, I would suggest you switch to a ball powder with a similar burn rate.

Problems will occur if you don't weigh thrown charges of ball powder every so often too. As the powder column in the measure drops, the weight of the loads will fluctuate. I've used baffles in the powder measures with mixed results and finally I gave up on them and decided just to weigh the charges at appropriate intervals when I use ball powder, every 10 with handgun loads and every 5 with rifle loads.

Extruded powders I load either by spoon or with an electronic dispenser, depending on the number of rounds I'm going to load. Light flake powder I always load with the spoons onto the scale as these tend to hang up in the thrower.
 
IMR 4350 meters horribly in dispensers compared to other powders...But I've done it and so have many others.

H 4350 meters better.

All powders meter the best via RCBS Chargemaster;)
