I don't own any vintage rifles so I'll always suppress any firearm I ever own. You only get one set of ears which is my primary reason for using suppressors.
A .22LR with standard velocity ammo creates approximately 140 dB of sound. 140 dB is loud enough to cause permanent hearing damage. Centerfire rifles can produce considerably more. A .223 creates approximately 158 dB. For reference, a jackhammer is around 110 dB and an ambulance siren 120 dB. Sound in dB is measured on a logarithmic scale. Sounds 10 times louder than total silence (O dB) would be 10 dB, and sounds 100 times louder than silence are 20 dB. Every 10 dB increase is a multiple of 10 times, so the difference between the .22LR and .223 is massive. If you're going to shoot it a lot, that's something to consider.
