One could go with a SMLE, a bandoleer of loaded stripper clips and practice the Mad Minute. *If one could find a good supply of British 303.

in a perfect world.......:o)
Till then my “truck gun” is an M1A.
Stay safe !
A few years back the venerable SMLE was available in an Ishapore model chambered in 7.62 NATO. I bought two of them. They're amazing rifles. Wish I'd bought 6 of them.
