I prep my brass by decap, then clean in wet tumbler with SS pins. I then anneal, lube and full length size bump the shoulder. I do not use the expander ball when resizing I use a expander mandrel and die size 263 to size the inside of the neck , then prime. I am loading 6.5 Creedmoor Savage bolt gun. I am using Hornady 140 ELD M with 41.7 Gr H 4350. I find that it takes too much force to seat the bullets into the cases. I think it has too much grip on the bullet. The brass is Lapua on the 2nd firing. I have cleaned the inside on the necks with a bronze brush and still find it takes too much pressure to seat. There is so much grip on the bullet when I pull a bullet it takes a lot of force to extract it from the case, it takes several tries before I can get it out. Any ideas what might be going on? Thanks in advance.

I noticed on my 223 lapua brass when I started annealing that the necks fought back where preannealing they worked easily. A carbide expander ball and imperial dry media applicator have made it smooth as butter again.
Don't clean the brass and use a FL bushing die. Your problems will disappear and you'll have more time to do things you enjoy instead of cleaning brass.
I've quit running my brass through SS media every time and only use it when the brass gets REALLY dirty. This keeps the carbon inside the neck which serves as a lube, of sorts. I've also started using dry lube on my case necks and the bearing surface of my bullets prior to seating. This really helps with a number of issues, especially the issue you're having with what's essentially new brass - seating bullets into bare brass necks.

.263 is the bushing size ?
Or expander ball size ?
What type of dies are you using ?
Do you inside chamfer the cases ?
Any slivers of copper around the bullet ?
Maybe I don't understand the expander bushing you're using but most full length non-bushing dies require the expander to reopen the inside diameter of the neck. On my whidden dies, if I take out the expander ball I get to much tension.

The expander mandrel size is .263. He's full length sizing and then expanding the necks back up in two separate steps.
