I have fired 20,000 of the PMC Optima's in all four gagues. Loaded them just like WW209's. I always try to load with the lowest pressure loads anyway and have not had any problems shooting them in my tubed gun. The only problem I have had with them, is every once in a I have one with what seems to be a hard primer. My supply for them had dried up but would buy more if I could fine them here.
