Strange quoting myself... but what the heck..
Today i pulled the 85gr that had the deep ring and tried a few things:
1) re-chamfered the neck... no improvement and even collapsed a few necks from the pressure. The seating die is not contacting the case in any way.
2) Annealed the case, still no better
3) Measured the expanding ball against my 25wssm one... exactly the same
4) used a nylon bore brush to scrub out the case neck and put some graphite powder. This made a huge difference.
5) then just used a nylon brush to clean a neck without the graphite, this also worked well.
Conclusion, must have been some residue on the inside of the neck causing it to hank up from new brass. Glad it is solved.
I have loaded up 90 gr Sierra, 87 gr Speer, and 100 gr Speer all with H4895.
Now all i need is the upper!
