Good to see this information. Thanks!
One reason I never quite got around to buying a Steyr Scout Rifle, was its inability for its magazine to be single-loaded from the top. It is possible to lock the mag in the lower position, enabling single-loading into the ejection port, while maintaining the magazine’s round in reserve, but that is not the same as being able to load as many rounds as I want, directly into the magazine, while it remains inside the weapon. Finding Steyr Scout DBMs, in stock, is not easy, which would seem to make the ability to re-charge the mag, in the field, with the mag inside the weapon, more important.
In the distant past, some time in the Eighties, when I briefly owned an 1903-A3, I never got around to acquiring any stripper clips, so I only loaded single rounds, from the top, but otherwise, recall little. In the late Nineties, after buying my second turn-bolt rifle, a left-hand-action Winchester Model 70 Safari Express, I practiced loading single .375 H&H cartridges, from the top, and did so with earnest diligence, as my wife had the fever to go to Africa. (We never made it to Africa.)
Of course, the huge 375 H&H cartridge is easier to handle, singly, than .223/5.56 NATO, and that is with warm hands. I’ll need to add a reminder, in my calendar, to experiment with this, in January/February cold. My only .308 Winchester rifles, at present, are Browning BLRs, whose DBMs cannot be loaded, while still in the weapon, but I can probably rig a mock-up, if I have not yet bought a suitable, currently-planned turn-bolt weapon, by then. (I hope to have at least one turn-bolt rifle, suitable for 100-1000-pound mammals, fully vetted by early November, and deer season is not the reason.)
