I thought there was one.

I don't know that one. My Lyman #46 shows a 358156 and a 358446. Both Keith type SWC's at 155 and 162 grains, respectively, cast from linotype. They appear to be the same bullet, but the 156 has a gascheck base, while the 446 has a flat base. Any chance you made a typo?

I just looked at what Marshall has, and his 160 grain flatnose should make a good substitute. He also has a 165 grain flatnose and a 173 grain Keith style bullet.

Scroll down in the bottom of the left column on this page under Bullet Selection until you find 38/357 and click on that: https://beartoothbullets.com/bulletselect/index.htm

Lyman mould number 146 was the 538146, a bit large for a .38 Special. Marshall does have a number of Lyman moulds and you could contract him about running some off.

Oh Im sorry! It was a typo - should have been 358-156GC. Yes. Thats the one. Suppose to cycle thru the levers in magnum brass plus be real accurate and with the gas check no leading in the carbines higher velocities.

Like Jack suggested, contact Marshall and see if he has it? Marshall's other bullets may still be a good choice because you can choose the diameter, which affects accuracy and leading. Slug your bore with pure lead (bullet casting alloys are too hard and will spring out to give you a false reading) to get its exact diameter, then get the bullet about 0.002" over actual groove diameter. That seems to work better in lever guns and revolvers, especially, than the standard 0.001" over-groove diameter cast bullet. The extra diameter seems to help increase start pressure enough to improve ignition and obturation consistency. The pressure increase is not enough to be a safety concern, as even bores for much harder jacketed bullets are often several thousandths undersize. I have an old French MAB pistol in .32 ACP that has a 0.309" groove diameter barrel for the 0.312" bullets. The military specs .308" groove diameter rifle barrels at 0.3065" to 0.3095", and that's with much higher pressure ammo than we're talking about.

You will find, if you shoot many cast bullets, that firelapping the bore will do more to reduce fouling than any other single step you can take. Get Marshall's technical book (included with his firelapping kit) to learn how to do both slugging and firelapping and how to choose bullet diameters.

If you find you have non-GC bullets that still need something to reduce fouling, try Neco's P-wads (http://www.neconos.com/shop/?shop=1&cat=16&cart=149541). These are plastic discs you seat under a cast bullet, and stop leading essentially completely, as near as I can tell. They occupy a sixteenth of an inch under the bullet, so you need to work your loads up with them in place. At a nickel apiece, they are 2.5 times more expensive than copper gas checks. That is OK for trying out the idea, but too expensive for volume shooting. Neco used to discount them in larger quantities, but you would have to ask if they still do? I make my own from a 4'x8' sheet of 0.060" low density polyethylene (LDPE), which is what the original concept was developed with, cutting them out with a punch I made. A sharpened case will do it, but is slow and hard on the hands. A sheet metal style hole punch press is better and faster, and it isn't hard to make one for a Lyman/RCBS style lubriszer.
