Thread: Effect of suppressor on performance of a given load...

It would be rare for a suppressor to cause a rifle to shoot worse. Due to added length they essentially give your barrel and depending on load you could get a velocity increase. By being quieter and softening recoil by design, people tend to shoot better with them fitted. Apart from a barrel harmonics influence, the rifle has always been capable shooting the same without a supp, its the firer who has improved in most cases.
You will never know unless you fit one.
