Thanks to everyone's suggestions.
I did notice that a few mentioned classes and/or competition. As I mentioned earlier; I do attend classes, it's part of my job; and I do compete (handguns) several times a year. Last year at a fund raiser pistol match, I was 6 points from shooting NRA High Master, and won 2nd overall from about 50 shooters. This year I shot Master again at similar match. I've competed in steel plate matches, bullseye, and IDPA type matches. I still love to shoot.....
I'm a rifle and handgun guy. No real preference over one or the other; except over the years, while I do appreciate its qualities, from a personal stand-point I just do not like polymer pistols, and not much love for plastic rifles either.
So, it's not really a "use" or "training" issue; so much as there's just not much out there, that's new or old, that is really screaming at me anymore. Like I reached a plateau or something.
I'm leaning to the precision route with rifles, and maybe a .50.....
