Duck,
Yes, your Henry should be able to cycle Schofield cases. But there are a couple of caveats. Some of the old build guns won't because of the difference in the dimensions of the carrier block about 15 years ago. The carrier block is not a problem on the "new build" guns. Also, with Schofield cases, the gun will be length sensitive. Nothing shorter than a 200gr RNFP. It won't like semi wad cutters in any length. You also need a good tight rolled crimp. Crimping with a .45 ACP taper die is a no no.
The problem depends on "where" you feel the hesitation in the lever stroke. It may be the case mouth catching on the breech face of the barrel (not very common unless "taper" crimped) or more likely, it is the cartridge guide at the bottom of the Breach Block (bolt) hitting the back of the case rim. If that is the case (no pun intended) you may need to work a bit of a "ramp" onto the cartridge guide to ease full chambering. Some guns will run Schofield cases with no "refining" of parts and some won't. Don't mess with the extractor hook, no matter how tempted you are. Bad joss there. These two situations occur on the closing stroke.
If you feel the "hic-up" as the lever opens the action, take a peek down the mortice the Carrier Block rides in. WITH A DUMMY round, watch the carrier bring up the round. The case rim MUST NOT HIT the front of the cartridge guide as it rises. If the rim hits the cartridge guide, you have a timing problem to fix.
