I will say that my favorite rifle is my 11.5. But I will not shoot that sum bitch without a suppressor. Anyone saying that sbr’ s aren’t louder ain’t shooting mine. My 11.5 bcm is freaking so loud and concussive that at my local range, where it’s isn’t uncommon for multiple magnum rifle calibers are shot at the same time, people stop me look at me like I’m shooting a cannon. I would defiantly go 11.5 to 12.5 range if it were me.
