I got in a trade some time back some "antique" (as in probably 1950s) field points. These points have no taper. They just slip over the shaft with no tapering of the shaft needed. What was the purpose of tapered field points in the first place? I can see that the non-tapered points will have a shoulder that makes them hard to pull out of really tightly-packed target bales. But the non-tapered points seem to me they'd be less likely to break off behind the tip.
Yeah, they're "antiques" and all, but I'm mounting and shooting these jokers!
