Pointed bullets? Yep.
My very first loading manual was one from Lyman/Ideal, printed sometime in the early 1960s, and gave loading data for bullets cast from their moulds. There were some fairly strange designs offered, too.
One was designed specifically for the .30 US Carbine, with a fairly short ogive which ended in a very sharply pointed tip. I don't recall if I read the explanation elsewhere, or simply deduced it, but it makes sense: The very narrow end reduced the area of contact, the amount of lead alloy touching the feed ramp, and lessened the "smear" deposited on the ramp.
I believe that pointy little bullet was of conventional weight for the .30 USC, in the 108 -- 112 gr weight. Remember, the carbine and its ammo was only recently released for non-military use back in that time, and people were still working out their loads for it. There was some thought that you could mess up your carbine by using nonconventional loads which did not exactly duplicate the pressure curve of military ball ammo. This is still a consideration today, but is not considered the HUGE matter it once was.
And an aside - - that particular bullet was favored by some trappers and fur hunters to lessen hide damage. The sharp pointed projectile loaded over a few grains of fast pistol or shotgun powder in .30-30, .300 Savage and the like did the job and obviated the need to carry a .22 for non-destructive finishing shots.
