Thank you all for this confirmation and education. my SSV300 has suffered since I got it in 2020. It just got to a point where I was like I have to do something about this and it can't just be me. Although when I took it to my local gun smith not sure why he didn't pickup on this.
I need help. I own the VICTOR 9" PISTOL BLACK 300BO unsuppressed. My first time shooting I used LAX Ammunition Factory New 300 Blackout 220 GR. HPBT Subsonic and it jammed. What grain should I purchase to shoot up to using a can? Thanks.
