I remember it. 357 Maximum. I never bought one, shot one or even got interested in it. I used to say, there's only so much you can do with a 38 caliber bullet no matter how fast you push it. Never owned a 9mm. (!!)
I have handloaded ammo for a friend who owned a 9mm. I had the dies and even picked up some brass here and there while I was picking up my brass, but I had no moulds (Sizing dies in 355) So I used 158 gr (.357) swc Boolits for a .38 because I did have those moulds) and just used starting loads and they turned out great and accurate. He shot a bunch of them.
I have cast different Boolits in 44 and have been handloading them for years and years and even bought different moulds in 44. If you own a 44 Magnum then you need to cast Boolits for it to be able to grasp the versatility of the cartridge! I have so many moulds in 44 from Lymans old 180gr WC, Also the 245 Keith, 300 Keith (GC), 255 LSWC (GC) Lee, and various weights in the 237swc/240RN and I've been loading them so long that I know the good loads! Starting up to max and tested most combinations. As far as Ruger goes that is, lol. I have .44's that have never fired a Factory cartridge! All have been hand loads!. My first 44 Mag that I bought myself was a used Ruger Redhawk (SS 5,5" BBL.) for $285. !! I bought a used Ruger Redhawk as my Christmas present because I couldn't afford a S&W 29!!
I picked up more than that too, later. Then I found out that 45 Colt will push more weight at less pressure than the 44 Mag so I bought me a FA 454/45LC and it was stolen after several years but I replaced it with a Ruger NMBH convertible 45LC/45ACP and that is a nice pistol! So I'm working my way through 45 Colt lately. It's not going even as fast as 44 mag did because...I'm in-between Chronographs (Lol). The more ammo you test, the more that happens sometimes!
