Good morning from Virginia! I wanted to say thanks for sharing your new boolits cast with old molds - I am a big fan of anything .38/.357/.35 caliber. I do not cast, but began amateur reloading for my hobby a year or two ago. I am also a total gun history nut - and learning about what was used and favored in the past by shooters is always an interesting thing to think about.
May I ask what what powders you like to use with these? And when you coat the bullets, does that negate the need for a gas check? (You can tell I'm new to reloading with these questions!)
Be well - and Happy Holidays

Adam for the #358477 I like W231 or HP-38 same powder different label with the only differance being in lot to lot variations which I haven't found to be even noticeable but it always a good idea to make sure before you load up a large batch.
For the #357443 I like Alliant 2400, I'm a big fan of 2400 in cast lead 357 magnum loads and it does double duty as well in many of my cast bullet rifle loads. Neither of the two bullets I post are designed to use a gas check. They do have gas check these days that you can crimp over plain base bullets but I just never use those.
I usually don't push the plain base bullets as hard as I do gas check bullets in handguns usually 1200 fps. or less depending on if it's for 38/357, 9 mm or 45 ACP loads as I use a 50/50 mix of pure lead and wheel weights with a bit of tin and powder coat. I usually water quench the powder coated bullets right out of the toaster oven if I'm going to shoot them in 357 mag. loads or HV rifle loads. The bullets don't gain as much BHN ie hardness as if you heat treated them but they get a little harder than air cooled wheel weights and using a gas check I have pushed the powder coated rifle bullet up to around 2300 fps. so far with good accuracy and no leading. Of course, I never had leading issues to begin with before I started powder coating my bullets, I just made sure the bullet fit properly, used a harder alloy and a good lube.
As to powder coating and gas check being needed or not that basically depends on so many variable too numerous to mention. I like to keep things simple when it comes to using a gas check, if the bullet is designed to use one at some point along the velocity / pressure curve a gas check bullet is going to just shoot more accurately with the check installed than not. For plinking loads that are low velocity / low pressure I leave the gas check off most all the time, I did that even when I used to tumble lube my bullets with Alox / JPW lube.
Powder coating has quiet a few advantage over traditionally lubed bullets I like the benefit of powder coated bullets.
