Static?

[JackSprat]

I recently loaded some 243 using H414,and noticed the powder sticking to the inside of my necks.At first I thought it was my case lube(oil) causing it,so I wiped all the inside necks out,and it seemed to solve the issue,but noticed on one that I dumped that the powder wanted to stick inside the body of the case.It acts almost like static cling,and even with pecking on the bench the powder was stubborn to get out..Did I somehow get oil way down in my cases,or can powder actualy cling from static?..

I've seen it cling to plastic surfaces like that of a funnel or powder measure due to static, but I can't say I've ever seen powder sticking to brass because of static. Any time that has happened, it has always been some other material that is attracting it (namely leftover sealant or whatever it is that is found around the bullets in some military type ammo, I believe).

depending upon your lubrication method, lube can indeed make it into the body of the case.

I bought my 243 dies off Ebay,They they are the Lyman dies,and are exactly the same as my 223 dies,but they are a real pain to use ,and the 223 dies are not..I don't know what the problem is with them,but they really take a lot of lube,and are the most unforgiving dies as far as denting the shoulders that I have ever had..I feel like throwing them over the hill sometimes..

Powder can most definitely cling to plastic parts due to static. I suppose it is possible that static can build up enough to cause it to bridge across a brass case mouth, but since brass is not ferro-magnetic, I would look first towards the residual lubricant.

When I prepare brass, I lubricate the neck of every n-th (sometimes 5th, 7th or 10th) case prior to resizing. I use a carbide expander ball so more lubrication than that is not required. After sizing, I tumble the brass to remove the lubricant and then I trim, deburr and chamfer the brass. I reprime after the sizing and trimming stage is done, so after this, I do not have a problem with static causing bridging in my powder measure.

I don't think that conducting metals can build up static electricity. Please correct me if I'm wrong.

Sounds like lube to me.
