Great to have you aboard!
If you have an addictive personality, or ADHD, or are a perfectionist… this hobby can get overwhelming- almost limitless possibilities for tinkering with different load combinations!
I’d suggest that you keep it simple, to start with. One or two powders, one or two projectiles, maybe only one cap or primer option, to start. You have the rest of your life to tweak your load!
I have an addictive personality, have a pretty good case of ADHD (well… maybe missing that “Hyperactivity” part!),
and I am a perfectionist!
I jumped in with both feet, and bought “one of everything.” I was going to be “that guy,” who dialed in the ultimate load for his Omega. I started with two T7 pellets and a 250 grain T/C Shockwave. It shot that combo just fine, so I just started shooting deer with it!
Twenty years later, I still have a variety of components left!
