22 Long Rifle ammunition uses a heeled bullet, to list a current common example.

Here is a couple of heeled bullets for the .310 Cadet

Here is a heeled cadet bullet compared with a similar Gas checked based bullet.

The heeled bullet has a small shank or heel that is the diameter of the inside of parent case. The mid or driving band will be about the same diameter as the out side of the case and groove diameter. And yes the grease groove was out side the case.

I believe some older revolver cartridges were made in this form.

Heeled bullets can also be used in 41 long colt, George.

[Ricochet]

Lots of older revolver cartridges used them. A few others include .32 Short and Long Colt, .38 Short and Long Colt, .44 S&W American, 7.5mm Swedish Nagant...

The biggest problem handloading them is that a conventional roll crimp can't be applied. A collet type die such as a Lee Factory Crimp Die would work well.

Sooo... it's kinda like a plain base boolit ??
The heel is for keeping the projectile "square" in the case neck ??
Was this design before the advent of the gas checks ??

Razor:

It's actually a very old design, from the early days of metallic cartridges and pretty much obsolete (for new designs, like the .44 Russian and .44-40 - with the greased portion of the bullet INSIDE the case rather than exposed like the earlier .44 American and .44 Henry) by the early 1870s. The heel allowed the main body of the bullet to be the same OD as the case, especially for conversions of cap-and-ball revolvers, by boring the cylinders straight on through. The .22 rimfires (except the .22 magnum) are the principal survivors of this approach. Gas checks are something else; they came in around 1900, when smokeless powders came into general use, and applied more heat and pressure to the base of the bullet, yielding increased velocity potential.

Here's an article from leverguns with some heeled boolit history. The authors have designed a new large bore heeled cartridge on a modern platform

They're also good in old guns that have larger bores then chamber necks, such as my 10.4x47R Vetterli Vitali.
