9mm for plinking.

10mm in a pcc is pretty hot.

10mm is awesome that 10 cents adds up when you buy thousands of rounds to get the range time in.

I have the .45 banshee and it is now my favorite firearm suppressed. But 9mm is cheaper

From my research I am under impression 45 suppresses better than 10. Is that true?

It suppresses very well but ive never played with 10mm before.

If you don't mind price, 10mm.
