Aguila super extra issues

Has anyone has issues with more recent batches? I’ve fired a few thousand without incident. Today took my Lakefield mark ii and an old garden gun to the range with a friend. We had a single box of CCI Blazer and a brand new 250 box of super extra. We couldn’t get through a magazine of 10 without a misfire with the Aguila stuff. The Blazer ran perfectly as usual. Both rifles we got misfires about 25% of the time.

I’ve liked this as cheap ammo before, but now I’m feeling like I threw money away.
