Hi, Norville:
Hornady #4 and Sierra #4 don't have data on the .356, so they may not recommend their bullets in it, or they just might not have got around to it. The Hornady RN has a pretty tough nose and I'd pass on it. The Sierra's nose is practically flat and you may want to give them a call.

</a> The Remington's nose is rounder, but it has the most lead exposed and it's pretty soft. It should be OK if the Sierra is. Winchesters have a tiny flat on their nose, but I haven't seen them for sale as componets.
Be sure your primer pockets are cut to full depth. You don't want a high primer in a tubular magazine. I use the Whitetail uniformer, now available from Sinclair.
