hornady has information on line as to the general intended use of most of their product lines. not so much in the naming all the time, but they do let you know what is intended for what.
if you email tech@hornady.com with a specific bullet question , they will happily answer what the intended use is for, min/max intended terminal velocity ranges for the bullet to "operate", etc.
just a few examples of product lines and their usage
v-max - poly tip varmit bullet - designed for violent expansion relatively shallow after impact on thin skinned game/varmints/predators
a-max(discontinued) & ELD-M (replaced the amax) - boat tail match bullet focused on extremely consistent jackets with polymer tips for increased BC. the only real difference between them is the tip material and a minor change to the meplat of the tip design.
eld-X - new long range hunting bullet designed for out past >400 yds. this is a high BC VLD style bullet for long range hunting up to around 800 yds if memory serves correctly. will still work well at 0-400 yd ranges too. medium to big game - elk, whitetail, mule deer, etc
SST - more traditional poly tipped hunting bullet. bonded, interlock ring, boattail design. medium game - whitetail/elk type bullet.
FTX - flex (soft) tip bullet for use in leverguns with tubular magazines. bonded, heavier jacket design, interlock ring to help control expansion. hunting bullet. also used in some of their straight wall cartridges (350 legend, 450 bushmaster, 50 beowulf) as well as some pistol rounds too.
interlock - more traditional soft point type cup and core type bullet. bonded, interlock ring, tapered jacket - just what you'd expect from a traditional whitetail bullet
interbond - modernized version of the interlock with a poly tip and a bit thicker jacket for punching thru heavier bone.
match - BTHP match bullet. swaged core, extremely precise jacket, your traditional style paper puncher with good technology in the design.
as noted - detailed descriptions on these bullet types available on their website.
i shoot a lot of hornady bullets, i think they're a good mix of value and availbility. red boxes adorn most of my reloading supplies shelf. i primarily use their VMAX, AMAX/ELD-M, SST, FTX & HPBT match bullets.
