Wonder if a .30 cal suppressor will work on the Ruger 7.62 RAR. I know the Russian ammo uses a .311 diameter bullet. Surely there's a little larger hole I the Supressor than .308 ?
If you want a quiet RAR, get the 300 BO. Fast twist to stabalize heavy for caliber bullets. To me the 300 BO is a more appealing modern alternative to the 30-30 in a bolt gun than the 7.62X39.
