Best 4.5mm Ball Bullet (Steel or Lead, etc.) for Air Pistol

[Zvinets]

Hi everyone, I would like to ask about what is the *Best (steel or lead, etc.) Bullet Ball brand for your airgun.

Speaking of details;
1. 4.5mm caliber
2. For Co2 air pistol
3. Overall performance (rigidity, finishing, "friendliness" for your airgun)

Let me know your trusted choice as I'm thinking of resupplying soon!

Cheers

If it is a rifled barrel never shoot bb's or any steel shot or you will have no rifling. I use H&N Sport Prazisions-Rundkugle copper plated lead shot in my Ruger .177 Pistol.
