Mine are dropping at .435 with range scrap, and .436 with Linotype, so I have to size them down just to tumble or pan lube them. If I powder coat them as cast, they size out at .438. That's a tight squeeze through my .432 sizing die, so I didn't powder coat them like I do with all of my pistol bullets. I am going to try a couple to see if they will fit through the sizing die without deforming them too bad, but I'd rather have them dropping at .431-.432.
I also have his 358429 170 gr Keith mold. I thought I was getting a .358 mold, but it is designed to drop at .360. Again having to size down more than I would like. They are dropping at .361 with range scrap and .362 with linotype.
I'm not the only one who's made this mistake. I've talked with another member on this forum who also didn't notice the diagram, and is getting bullets dropping larger than he would like. I think his molds are very reasonably priced for the quality, but check the diagram before you buy so you get the size you want.
