In case anyone here is interested in the 41 Long Colt, there was a production run of MiHec moulds made for the 41LC. They are brass, two-cavity, hollow-base moulds of 200gr. They are very similar to the Lyman/Ideal 386178, only better. These have deeper lube grooves, which are welcome if using black powder.

There are reportedly 10 extra moulds left from the order.
