totse was wellknown as the shittiest of the shit tier forums in that regard.
Filled to the brim with 13year old idiots talking shit and ripping off old textfiles that ware shit.
If it came from totse it will either kill you or not work.
Zoklet was a tiny bit better, there ware some folks who knew chemistry, but they mostly concentrated on drugs instead of weapons.
Roguesci aka "the explosives and weapons forum" was a good thing as long as it lasted. Strict moderation and good info.
Out of stuff that still exists sciencemadness.org is the best on the chemistry side (energetic chemistry they call it).
For weapons I'd look at homegunsmith.com, weaponsguild.com/forum/index.php, weaponeer.net and so on.
But seriously, as long as totse existed it was considered the worst in any aspect it covered and most of it's articles ware ripped from other sources. But I recall a thread from there where some kidiot was building a .308 handgun from copperpipe and epoxy. Did not find the thread agian on a later date to verify it the idiot managed to kill himself or not.
But I'm not aware of any zoklet or totse mirrors.
These RogueSci mirrors exist:
