Been lurking for a few years but now have decided to start making boolits in 30 caliber, initially for my 308 win and eventually for a 30/30 mod 94 that I'm looking for used.
I have a couple of questions that are puzzling me and hope that someone can stop me scratching through my hair.
I bought the Lyman 4th edition casting manual and, tbh, am disappointed with it. eg it advises sizing 308 win and 30.30 to 0.308" yet advises 0.309" for the 30.06.
Many of the you tube videos recommend sizing to 0.309 for both the 308 win and the 30.30. Which is correct, 308 or 309?
Also the lyman book drones on about metallurgy of lead but I can't find a reference to the material to be used for subsonic rounds for the 30.30.
I recently had my roof extended and I have about 3/4 of a roll of pure lead (about 200 pounds) so I'm quite keen to use this.
Is this ok with gas checks in the 30.30 with mv around 1000 fps.
The reason I'm asking is I want to use the 30.30 in cowboy shooting as I got fed up losing so many 357 cases in the grass with my 94 win in 357 and the 30.30 cases are so much more visible.
We have to use subsonic rounds as the range is in a noise sensitive area.
I also have some much harder lead alloy but am going to use this with gas checks for deer hunting with my 308.
Any helpful suggestions would be appreciated.
