Maybe the Interlock gets more raves becaue it often looks prettier when found under the hide on the far side, a classic mushroom back to the Interlock ring.
I think that's quite possibly true. (What a fickle bunch we are eh?
)
Somebody else mentioned the ProHunter (flat-base) versus the GameKing (boattail). The general belief is that boattails tend to separate more easily, because the tapered rear of the jacket doesn't grip the core as well as a "square" rear. I used to believe this myself, until one day when I went through all the recovered bullets I've filed away over the years in a couple of big tackleboxes. There are a quite a few of these, and it turned out that twice as many FLAT-based bullets had separated jacket from core as had boattails. So I quite worrying about it, and since then have used whichever one shoots best.
Every time I've seen you mention that - the first time, I suppose, in
Rifle magazine, I think of one particular Speer I collected; not the Hot-Cors which are "fused":
