If you are speaking of hollow base wadcutter target rounds the assumption was, and is, that the base of the bullet would upset a bit and help engage the rifleing of the bore while maintaining an up front center of mass for the stubby little round.

And if you invert those bullets and make the hollow points, the killing power is damned-near double, for say, a .38 Spec.

LONGRIFLE30 , Yeah, I tried that back during my novice days.
If you want to shoot targets with a 38 spl. the 148 gr. hbwc is great, if you want to invert it and load up some rounds that is fun too but not accurate. Target bullets loaded correctly or backwards do not usually make a good defensive round.

It's a pretty old concept, going back to the minie ball. Was supposed to expand and seal off the bore behind the projectile to provide velocity

Hollow base Wad Cutters

Iload the following loads:
HBWC...3.0 grains W-231
BBWC...4.0 grains W-231
If I load the HBWC with 4.0 grains, it will key-hole.

Before I knew better-

I use to load Speer's 148 grain HBWC backwards in
.38 Special case's, as a defensive load. Great threat
stopper; but not very accurate over about 15 yards.
Now, I wised up; and can be found toting Federal's
.38 Special +P Hydra Shok's in my Smith & Wesson
vintage model 60.

So what are the advantages, exactly, to hollow base SWCs?

I always thought that SWC bullets were only good for paper punching.

WC vs SWC

Two different things. A wad cutter is flat across the front end. Where the pointy end usually is. They're designed to make neat round holes that make target scoring easier. They're also easier to swage as opposed to casting. Swaging is literally press forming bullets out of lead tubes. WC's are normally very soft and the hollow base will expand to fit the barrel much better than a cast bullet. Therefore providing much better accuracy.
A SWC is designed allow heavier bullets that cut nearly the same neat round hole in paper but give a bit more whump at the receiving end. In the olden days, when cops carried .38 Specials, SWC's made it more effective on evildoers than the round nose bullet that was known to bounce off car windshields. These days, the cast SWC is usually only seen on target ranges as the HP is far more effective than a SWC.

Almost explained

Full wadcutters are cylindrical and to protect the fragile corners, all of the bullet is usually contained in the case. The bearing length of such a bullet shoved that far into the case is quite long and if it weren't either tapered to smaller than .3575" or made hollow based to allow for deformation, it would bulge the case.

For target work, a loose fitting bullet is patently objectionable and a tight fitting case is deemed helpful. Bulged cases are problematic especially in tight chambers HBWC's to the rescue.

These can be deep seated yet expand to fill the rifling, keeping fine accuracy. They are usually soft lead and do not withstand anything more than light loads.

Therefore, BBWC or beveled base wad cutters. You guy's really have me wanting to load up some of this stuff and take some 38s to the field!
