That’s a good rule. Up here, the idiots won’t let us carry sidearms, the paperwork is nuts.
I usually take a ruger scout 308, or 45-70. The scout is better though, I hand load and for accuracy and light weight and short barrel, it works well.
A friend of mine bought one years back. Got a nice scope ring on his face first time he shot it. I said, “Norm, it’s a .308 and the rifle doesn’t weigh anything. Don’t you know better?”
