Don't know for sure, All Ammo has all kinds of stuff. Beware of the older stuff as it may have corrosive primers. I have 18rds,some with yellow paint on the tip and probably corrosive I'll give you.
yeah, he states right up front that it has a corrosive primer. but hey, i don't shoot the old stuff so i don't know how big a deal that is if you clean it right away anyhow. i do buy ammo from that guy so i just looked to see if he had any.
I've had some quality issues w/ the POF stuff. Odd group sizes. A few that didn't sound right. With a few rounds the brass started delaminating. Maybe it was just a coating but I decided not to risk it. That was from a few different boxes. Unfortunately, other than factory stuff, its all I've been able to find lately.
Corrosive primers are a good thing. It means your ammo will go bang 30 years from now when you pull the trigger. Corrosive cleanup is the same as you should do with any ammo. Pour a gallon of hot soapy water down the bore, then dry it patch it, and oil it. Done in 20 minutes.
On the other hand $0.50 per round is getting close to Hornady and Privi Partizan prices, and their brass is reloadable.
