I just went through this.
The oil on the first round didn't work for me. I laid out a silicone cleaning cloth and dropping a box of CCI sv on it and just pushed them around for two seconds and shot them, perfect not one fouled. Went through 200 like that and every one shot fine. After that I just started shooting them dry and the gun works perfectly. Maybe something got lubed or broken in not sure but so far so good. It's worth a try .
Good luck , Tom
