MLers should be loaded before going to a blind. Not primed, or capped, of course, but loaded. That insures the main powder charge is loaded in a dry barrel. Since hunting with a MLer is a ONE-SHOT deal, RELOADING in the blind, IMHO, is also not an issue.
There is no good reason NOT to use a wooden ramrod, if you use a good one- no grain runout-- and you use the hand over hand method of pushing the rod and PRB down the barrel. The lower hand remains at the muzzle and is used as a muzzle guide to keep the stick( ramrod) straight, and away from the sides of the muzzle as it is pushed down by the upper hand, which grabs the stick no more than 8 inches above the lower hand.
That technique keep you from rubbing wood off against even a sharp, squared crowned muzzle, and keeps you from breaking any wood Ramrod.
I made a heavy wood loading rod for my 12 gauge shotgun, because the factory one was worse than totally inadequate, and had grain run-out. The stick is about 8 inches longer than my barrels, and wears a large Doorknob shaped handle I turned out of a block of walnut on a friend's lathe. At the other end of the stick, I glued and pinned a commercial ferrule, tapped for 10-32 threaded fittings. I bought a properly sized cleaning jag. That rod is NOT carried in the gun, but goes into the field with me, carried down my back. The jag is placed behind my belt. The top is centered on my spine, and is held by the weight of my possible's bag and its strap over my shoulder. The "doorknob" rides above my head, but when hunting birds in open fields it poses no obstruction to movement. If I were making a ramrod up for use when hunting in woods country, say- with my fowler or rifles-- instead of the large Doorknob handle, I would make up a skinner, longer, straight handle, like you see on files, and shorten the rod enough that the stick would not be above my head, but long enough to clean and load the barrel. On really long barreled guns, I would simply carry the rod laying it along side the barrel, and held with one or both hands. I had to carry my Ramrod out side the pipes one day deer hunting, as the wood had swollen after being out in fog, rain, and mist all day, and I could not get the RR back into the stock of the gun. It worked out just fine.
I prefer to remove the stick from the gun's pipe, anyway, when on a stand, and place the rod with the Jag down, leaning against a tree or other structure at hand, so that I can get the stick into the muzzle with a minimum of movement of either the rod or my hands.
And Up-and-down movement done this way can be hidden behind even a small tree, where an arcing sweep of the stick as its removed from the pipes under the barrel( along with the noise that often accompanies such a move) will alert, and scare not only game, but other small critters in the woods, that will give out alarm calls.
I am not against using metal rods for ramrods in any gun. Other than that 12 gauge shotgun, the other guns have both wooden ramrods, and Metal "Range rods". I do all the loading of these guns at the range, or at my car when loading them for a hunt, with the range rods. The wooden rods are only used to clean and reload in the field. They are more quiet to use, and do not give off alarming " clanks" like metal rods do in the woods.
One benefit that you might want to consider, particularly with a large caliber, shorter barrel gun is that the weight of a solid brass RR will help steady the muzzle and front sight when bringing the sights to bear on game, shooting off-hand. Its of lesser importance if you either have a shooting stick, or use standing rests when shooting at game in the woods, but that extra weight under the barrel can be very helpful in fighting off " Buck Fever ".
