So a small base is something more for a semiautomatic. I was getting that idea, as I was reading about a full size die set for .308 which they warned should only be used with bolt action rifles. I don’t really understand the why fully, a bit vaguely.
The .308 dies for me would be for a 308 semiautomatic.
I don't have a semi-auto .308 so I can't speak to that caliber specifically, but I use regular FL sizing dies for a couple other semi-autos (5.56 and 7.62R) with no issues. I think the problem some folks have is that certain rifles ("nice" ARs) have a pretty tight chamber and want a cartridge as close to original SAAMI spec as possible. This makes sense depending on the rifle, although my AR eats anything from match grade to range-pickup handloads, as did my old KelTec SU16. I guess it just depends on the rifle. Seems like it shouldn't really matter at all to an AK, which has more slop than a Matt Gaetz fundraiser.
As to the Carbide question, the only benefit I can see to using these more expensive dies is that carbide needs less lubrication in the resizing stage and *may* last longer if you tend to resize dirty brass. I have some carbide pistol caliber dies and they are nice, but IMO not worth the extra money. I just use a little swipe of coconut oil on every third casing and run em through the regular old Lee dies. Just remember to wipe the oil off with a rag soaked in degreaser / rubbing alcohol after resizing.
