Ooh I really like this idea of knock out value. My dad is getting ready for a spring brown bear hunt on AK peninsula next year and we’ve been having the discussion of energy vs bullet diameter. The .338 RUM/Lapua with a 300 gr Berger absolutely blows away the .375 Ruger and .375 H&H in energy...
I only cleaned my new bartlein carbon barrel until it was broke in and shooting tight groups under 0.5moa. I haven’t cleaned since. I would never clean right before a hunt, especially.
