Hornady Powder measure Problems

I am getting some pretty big inconsistencies on my new hornady powder measure. Most of my throws are showing a .3 to .5 variance from throw to throw---- with some as much as being close to 2grn difference from high to low. I don't expect it to be exact each time but these seem like large inconsistencies. I have ran more than a pound of powder through already to try and 'break it in'. I have degreased and lubed - twice now - with hornady cleaner and dry lube, as recommended. I have also ran some graphite powder in it for further lube. When the hopper runs out I do not have any issues of powder sticking, so I assume that is the case the entire time. One thing that is happening is on most throws the rotor gets jammed about half way on the way up. I am assuming that some powder is getting stuck between the rotor and body and I have to apply a decent amount of force to release the charge. Not sure if this would be causing more/less powder in the rotor to cause the inconsistencies?

Anyhow, curious if anyone has ran in to this issue and found a remedy. Or maybe the differences in grain wt I am seeing is normal. Thanks for any insight.

With long extruded stick powders it is not uncommon to get 1/2 grain deltas in the charges. I have a Harrell's precision powder measure and still get some rather large deltas depending on the powder. That is why I always throw a charge and trickle up to my desired weight on a calibrated balance beam scale. I am within a kernel or two and the consistency shows in my long range groups.

Return the hornady and get either a pact or rcbs chargemaster. Also not sure but on my chargemaster my brother machined an insert which basically extends the tube and eliminates overthrows.

I agree with the RCBS chargemaster. For stick powder, it's the best. You won't be disappointed with it.

For plinking loads you're close enough (as long as you're not near max) but for real work the only way to get what we've all come to expect is to throw them under weight and then trickle up to your target weight on your scales... or use the system denoted above.

I've weighed every rifle round for years, except some 222, 223, 22-250 and 243 for running jacks, and it's the only way to know with certainty what I have.

Or... move from the extruded powder to ball powder. That stuff meters like crazy but there are some issue with temp sensitivity with some of them.
