I used the Dowel extraction trick today and it worked great. As it turns out the only m10 1.25 bolt I had that was long enough was an old case bolt. I use a combination of two 1/2" drive impact sockets and a wide 2mm thick washer against the case. I did not have to add any extra washers before the dowels came right out.
With the case bolt you need about 6-6.25 inches of socket/ tubing for the case bolt to pass through. As mentioned before make sure the opening is large enough to pull the dowel into.
Oh man, I am sorry, I missed your post above with the link to the cleaning brushes , I would have steered you towards the gun brushes. Those brushes you got are fine too. You can snip off the round loop/handle and chuck the brushes into your cordless drill and do the same thing I do.
For anyone else, you can order gun brushes from Amazon, Brownells, Midway or Cabellas
Here is a variety pack on Amazon that will work for most/all of the holes in the cases and heads
