If you order from either of the Corbin's (swage.com, rceco.com) and they quote a particular month for the delivery date, do be sure to ask which year!
RCE tends to be a little bit faster, and a touch less pricey, but both are backlogged, and have lots of wait involved. Neither is particularly cheap, either.
.22 cases for jackets works pretty good, it started the Speer Bullet company. As mentioned, they cannot be driven to extremes, so plan accordingly. Gophers seldom can tell that you hit them with a bullet that could only shoot 3/4" groups...
J4 jackets can be got through a Berger dealer. Not cheap, but no excuses to be made about the jackets, if the bullets don't shoot well, either.
I've been looking at swaging for a while. Have not took the plunge, yet.
