Is this color normal?

Hello,

This is my first venture into slugs and into pcp rifles for that matter. I received a few days ago a tin of H&N slug HP from PA and some fx hybrid slugs ( most of them were all over the box but that's a different matter). To my question now, the FX slugs look nice and shiney and the H&N have this tarnished color on them. Is that normal? I thought I read a few days ago someone saying that they didn't shoot good if they looked like that? I hadn't had the chance yet to shoot either.

Hello Elgreco,

As biohazardman has already written: Unfortunately we have had a problem with some production lots (until August 2020), the coating changed color over time. That doesn't affect precision, but looks awful. I apologize for this mistake.
We have changed the process, newer lots will now look OK.

Best regards
