I have a 6.5 SAUM and a 6.5 Ott six… I’m thinking about buying my first suppressor to decrease the muzzle blast volume… I also have a seven mag… I am wondering if I should get a 7 mm caliber suppressor, a 30 caliber suppressor or a 6.5 caliber suppressor?? How much does it matter if you’re shooting a smaller diameter round than the exact di for the suppressor?? I’ve never had one but have several different rifles from 338 to 243 caliber and just wondering if I’m only going to get one suppressor which one should I buy in terms of Diameter of hole in it… Thanks for any advice
