My first center fire rifle was a pre 64 Win mod. 70 in .264 mag. The deal included a Lee Loader and a few mixed bullets. I still have the loader set. I keep it to remind me of how sadistic loading can be without the correct tools. LOL My dad and the LGS owner both tried to talk me into something smaller but I had magnumitus! Took a whole weekend to load a box of shells, and only a few minutes to figure out you were suppose to use sizing lubricant!! SAE 30 w oil and Vaseline don't count, but actually work for a bullheaded 14 yr old. Man did I ever dent up a bunch of shoulders, and stick a bunch of cases in the sizer body. Didn't take long to figure out belted cases don't last long full of 4064 and pushing 120 gr HP at around 3600 fps. Pretty tough on neck shot deer and would literally turn a nice prime red fox into furry snow. Had a bruised shoulder from November 1 st to middle of March and developed a small flinch from that rifle. My dad just grinned from ear to ear when I traded it for a Savage 24V in .222/ 20ga..
I'm to the point where I have favorites in calibers / gauges and platforms and I'm not looking for any new calibers, just refining what comes out of them. I have working guns because I'm a trapper, and have guns I'd hate to get wet. I'm concerned with what happens on the receiving end, because I market all my fur. My oldest is the .45-70 and my newest the .32 mag. I enjoy shooting .30-30.,.32-20, .44 mag(both rifle and pistol) but shoot .38 spl. the most. In shotgun I like the 20 guage and it's LW platforms better hunting pheasant, but the 12 guage offers more options in self defense. I like casting and loading for all of them. I look at a bucket full of wheel weights as a challenge!!
