In cheap 9mm brass practice ammo I have three choices. Yellow box Remington, white box Winchester and Federal Champion. Its there any difference in reliability with these three in an HK P30SK? I had two stoppages yesterday with the Winchester, both stove pipe jams. I have not had any issues yet with this gun till yesterday. Just hit the thousand round mark. The manual insists on brass ammo only.
I did purchase some over pressure Federal Aluminum 9mm that locked a Shield down tight that I used to own. Been a little wary of Walmart since then.
So does it matter or not?
