Checks before using a suppressor??

[mstarling]

Gentlemen,

What checks would you do before running a suppressor on a 300 BLK rifle?

1) Visual inspection of bore of rifle with mounted suppressor
2) Check for stabilization of projectile at short range without suppressor
3) Check for stabilization of projectile at mid range
4) ???

Will be running a Paladin Machine Services 16" barrel and a .308 cal rifle can.

Thank you!
