In the irrationally contrived scenario which is presented as the raison d’être for the scout rifle, carrying multiple loads for various scenarios is contraindicated. The (silly) premise in which we’re carrying one rifle which could be deployed with equal likelihood on small game, big game, or assailing forces dictates a simplified solution, and carrying multiple types of ammo for the specific varying target types beyond the muzzle opposes the philosophy.
Personally, I’ve seen the comparative results of others and done the comparison myself - forward mounted magnified optics suck, and fail to deliver on the Scout Rifle promise of faster acquisition. Stripper clip loading is a paradigm long dead, with the evolution of reliable DBM’s, and partial top-off’s, eh, again, we’re living in this fantasy world of needing a tactical (partial) reload between a sustained firefight… but ignoring the availability of DBM’s, some of which can also be topped off while in the rifle…
So yeah, “scout rifle” might carry a certain gravitas with a certain crowd, but I lend about the same credence to those folks as the folks which find gravitas in the phrase “flat earth.”
I do have multiple loads for some of my rifles, meant for differing applications, but then again, I also often find myself using just one load in some rifles despite deploying for disparate applications. Perhaps more similar to the paradigm being presented, however - when I was young(er) and still believed in “breaking down deer,” I knew my favored factory ammo of choice - the Winchester Ballistic Silvertips - had a chance of failure if impacting at close range and high velocity. So I loaded my magbox with the BST’s, but then chambered a Win PowerPoint for my first shot to be fired. If a deer came out at distance, I would cycle out the PowerPoint and send a BST after it, but if a deer came in hot and got too close before presenting a shot, I had the reduced expansion of the PP ready to send… it worked, but it was just a silly mess to invite into my life, and I outgrew it quickly.
