Have you tried any of that PMC X-TAC 62gr?
I haven’t tried the X-TAC yet. I have used PMC .223 55gr and it was flawless.
Most of my 5.56 is Privi 55gr M193 boat tail, and it works great too.
I’ve also used the Privi M855 and found it good also.
I still haven’t tried out that Frog Lube yet, But I’ve got a few days off from work this week, so I’ll try it on the pistols and let you know what I find.
