I am considering buying a suppressor but could use some info before I start getting involved in all the Class 3 paperwork and wai times for a can. I have heard conflicting reports about a suppressor for .300 win mag. The first one is any .308 can is fine. The other is that a .308 can wont have enough volume capacity to effectively suppress the sound and I should consider using a suppressor for a .338 Lapua to allow for extra gas volume to make the can work. Anyone out there with any real experience with these setups your input would be appreciated.
