Nylon brushes for 30 cal too soft

[JMayo]

I bought some brushes for my 30 br, proshot I think.
Its so soft I can't tell it's in the barrel.
I figure the guys with 308's have experienced this.
What brush is the pick for 30 cal for the "Think Tank" here.

What does the brush OD measure?

Bore Tech brushes are stiff.

All Ive used is Losso and Boretech and the Losso were a lot stiffer and that was .308 brushes also...

Tipton bronze brushes is my choice for cleaning.

 

[Dusty Stevens]

Pro shot bronze brushes are the choice. Brunos sells them in a dozen bag

If you prefer nylon, buy the blue ones.....Iosso

I've used both the Iosso and Bore-tech Nylon brushes . And a Bore-tech .338 Nylon brush to work the neck area of my TR rifle . What's a carbon ring ? Duh....
