Hollow based bullets were used in many different kinds of guns, both MLers, and breechloaders. They are still shot today,-some simply lubed in the grease grooves present, and others paper patched. The Wax paper "slick" is used to keep any wad from "sticking" to the hollow base- and is also used with plain-based bullets to keep the wads from sticking to the base of these bullets. Wax has a much lower coefficient of friction, than grease, so with the high RPM placed on lead bullets leaving the muzzle, that bit of wax paper tends to leave the base of the bullet very quickly.
I do not have much personal experience shooting hollow based bullets. Mostly, I have spotted targets for other friends who do shoot these kinds of bullets. But, as you well know, spotters are intimately involved in every aspect of load construction, since its the spotter who first sees when a bullets leaves the group, and misses the POA.
My brother gave me some Hollow based, paper patched bullets to try in my Springfield, but I have not done so. I finally have them figured out after several posts about PP bullets, from our own IdahoRon, and now feel Like I may be competent to actually load them correctly, and hit something. I have spent a lot more time shooting cast, plain based bullets in both rifles, and handguns.
FWIW, I am still skeptical about putting grease in those hollow bases, but I have seen some amazing shots made at target matches with that being done. Better shooters than me seem to know how to make that work, and that is why I commented on it.
