IOSSO vs JB bore paste

[46and2]

I have a tubb of JB for throat cleaning but I was wondering if IOSSO would be better for preventing/removing carbon rings?

I have not had any problems using Boretech eliminator and JB. But maybe Iosso is easier on metal.?

The sharpness of a throat is important. Iosso will move throats faster than JB. I have went back to JB, but not until its needed.

Thanks. Yeah, I only use JB every 150 rounds or so, or if the borescope spots a carbon ring whichever is longer.
Sometimes I will use it in the first couple of inches to smooth the edges of fire cracking ( probably doesn't help though).
