Your adapter is good because it takes .32 S+W (lead bullet), what's the use of the .32 acp ones for the .30/30, most factory .32 ACP ammo you are going to find is going to be fmj, useless for hunting in Canada pretty much. On the marlinownersforums a guy worked up a load with a .314 lead round ball, a .22lr case full of bullseye, apparently this fellow was getting pretty nice groups at 50 yards with this load in a Marlin 336 (.30/30), he was using buckshot so the most expensive part of the reload was the primer. I suppose the Hammond Game Getter is another good choice too, but the thing is unless you get more than one you are sort of restricted to a single shot but in the Hammond's favour, you can use rounds for a Powder Actuated tool, (although these are expensive) nothing fancy required except for the bullet (he recommends a lubed bullet with a gas check if you are using the heavy loads).
