Thread: 1 suppressor for different calibers

From memory the difference between .223 (5.5mm) and 6.5 is 1 mm or 40 thou

half a mm (20 thou) clearance all around the 6.5 projectile as it exits the suppressor is normal, using a .223 in the 6.5 suppressor probably gives 1 mm clearance all around the exiting .223 projectile.

The pressure wave from the lower powder charge in the .223 is easier to slow down and cool as well so the larger calibre suppressor is not having to "work" as hard

Don't forget you can get two or more extra baffles just to make it epic quiet

Exactly with the 308 (7.62mm) and the 243 (6mm) and about the same charge there was not a lot of difference. So with a 6.5 and 5.56mm (with a lower charge) there will be no issues.
