Ok, it's a new one on me, maybe I just never noticed before. The question is why?
Would the hollow base in something like Berry's plated round nose allow for a loaded cartridge with more internal space, allowing for a lower pressure at a fixed charge and COAL, or not so much? I have some of the Berry's 100gn .380 hollow base round nose projectiles, haven't gotten around to loading them though
I think if the HB bullet weighs the same as the flat base. has the same nose shape, and is loaded to the same overall length then it takes the same internal space. Just a slightly different shaped space.
The HB allows the bullet to obturate more at a lower pressure and allows the bullet to have a longer bearing surface. Could result in better accuracy. I just loaded some from Berry’s in 45 acp. Haven’t shot them yet. Gun club is closed due to the virus. I’ll report back when I try them. This is turning into a free ad for Berry’sWould the hollow base in something like Berry's plated round nose allow for a loaded cartridge with more internal space, allowing for a lower pressure at a fixed charge and COAL, or not so much?

The plated "hollow" based bullets I've seen are marginally hollow based, more like "dimpled" bases and perhaps they are trying for the "arrow effect" to improve accuracy; more weight forward...
Jes an old guy's thoughts, I obviously don't think much of plated hollow based bullets...
Not to change the subject, but using so called "hard cast" commercially cast lead bullets, especially the ones with beveled bases, plus powder charges that "keep the speed down" is often a recipe for "lead fouling and general mess."I tried cast lead .38 special for my GP100 stainless once.... despite keeping the speed down, I had never experienced such lead fouling and general mess.
