Im just getting started loading rifle, ive been doing pistol for a little while. anyhow, i was loading up my first 3 test batches of .223 on me lee turret, im having problems with the powder not going into the case, some gets gummed up and spills out when the case comes out of the powder through die. tried adjusting it up and down, didnt seem to help. lube left in the mouth? static electricity? humidity? i couldnt figure it out. it was worse with h4895 powder than the a2015.
Try a ball powder like Accurate Arms 2230. The stick powder such as H4895 creates a "traffic jam" as it enters the little case mouth of the .223.
hmm.... this seems like it might work. i will see if i can get it working a little better until i shoot up what i got, then off to find a ball powder. is there a way to tell on powders what they are without looking?
Some of the reload books have a break down of powder types--ie stick, ball, flake, disc .
Some powder measures have different sized drops for various case mouth sizes. For instance, you would use a different drop for 223 than you would 308. If the wrong drop is in place, it can spill powder to the sides of the case etc....Ask me how I know? hehe

I have problems with static when using stick powders. I would change to the ball powders as others have suggested. Bought some, supposed, static free funnels from Brownells. Have yet to use them so I guess they really are static free for now anyway. 
Try brushing your cases after you chamfer, I bet you've got a bit of lube in the neck. I've had some great luck with Benchmark in my bolt gun. It trickles well so with a good scale you can really dial in your load.
