For the 350L, I do not expect that carbide sizers will ever be available for a reasonable cost. The round is just too long.

Actually now that I think about it, there is a wildcat that does fit the OP pretty good, the Mini Mole. It is made using the 357AR reamer, but it is not run in as deep. It uses a much shorter case (same length as 360 Dan Wesson). With the longer case and higher allowed pressure, power level is closer to the 357 maximum than the 357 magnum. Since you are cutting the entire neck & shoulder off of 233 brass it is a whole lot easier to make than the necking up required for my 357AR. You load ammo using standard 357 pistol bullets seated deep enough so that the nose is just short of the side rib of a 223 magazine (Similar to the 300 BO concept). You get full capacity out of standard 223 magazines.
