Some cases are difficult to find and have to be made by forming other common cases to the desired caliber. Some involve just shooting a live round in the gun as is the case with an "improved" cartridge. Others involve necking the parent case up or down to accommodate the new caliber like converting .30-06 cases to .35 Whelen.
Some, like the 7-30 Waters, need to be resized by necking down a .30-30 case and improved by firing the round in the gun.
Below is a sequence showing the progression from .30-30 to 7-30 Waters.
From L to R: .30-30 cartridge, .30-30 fired case (empty), Necked down .30-30 case to 7mm in the full-length resizing die, Necked down and fire-formed case (now a 7-30 Waters case), Reloaded formed case with a 120 grain Barnes-X bullet.
Below is the T/C Contender in 7-30 Waters caliber. Not such a great rifle cartridge but a very good pistol cartridge for hunting deer and hogs. It is a better choice than .30-30 in both a pistol and a rifle due to the greater powder capacity and (in the pistol) a more aerodynamic bullet since it doesn't have to have a flat nose to avoid accidental discharge in the original tubular magazine.

Probably no one else on the forum is doing this sort of reforming but it's easy and mandatory if you have a gun that shoots an obsolete or hard-to-obtain cartridge.
