.25 acp cleaning brush?

Hello everyone, I just wanted to ask what phosphorus bronze brush can I use for my .25 acp Tomcat. I have gun to different specialty stores to look for a brush, however; I cannot seem to find a brush for a .25 acp. Is there a comporable brush that I can use that will do the job. Please let me know.

I use worn .25 bore rifle brushes that had previously been used in my .257 Roberts rifle.

6mm/243 should work fine.

Hello everyone, just wanted to say thank you for the information. I went out this weekend and bought a new brush from your recommendations. Thanks again.
