I started loading with my buddy back in the late ‘70’s. .38 Specials and .357 Magnums on his Rockchucker press, and then added dies for my .243 Win. Got my own press (RCBS RC II, of course) and started down the rabbit hole. Over the years, I have loaded .223 Rem, 22-250, .243 Win, 6mm Rem, 6.5x55, .270 Win, .270 WSM, 7mm-08, .280 Rem, 7mm Rem Mag, .30-30 Win, .308 Win, 30-06, .300 Win Mag, and .338 Federal to go along with handgun cartridges 9mm, .40 S&W, 10mm, .45 ACP, .44 Mag and 7 TCU.
Along the way, added a Dillon 550 for the 9mm, .357 and .44 Mag. Also for the .223, but rarely use it for the bottle neck case. Probably should try to swap my .44 Mag stuff for the Dillon .45 ACP, since I no longer have a .44 Mag…
