This gun is my first PCP too bro. Keeping it to pellets is fine. Especially since your gun isn’t a slug shooter at stock settings… but if you stay with pellets it’s gonna be a struggle. The only guys I see shooting 100y+ with pellets are doing so with $2,000 Fx guns or Brocock or something like that. The level of difficulty is much higher with pellets because of their ballistic profile… out to 50-60yard pellets will outperform most slugs. Or at least that’s what I keep reading/hearing. But 100y+ with pellets is not easy. If you’re just starting off with airguns you might be setting a very challenging goal. Not saying you can’t do it. Just that’s it’s gonna be hard. With a pellet at 100y you can expect between 18-24” of drop, minimum.
