The slugs look like Linotype to me also, very bright almost zinc or tin coloured.
But acted like pure lead.
I did also notice something.
I had a few rounds of Fiocchi Law Enforcement Slugs.
They are the same slug.
I took one appart and the wad on the factory slug is set deeper into the slug,
all the way up to the plastic ring ( See picture you provided above )
I wonder when and why they changed this ?

It looks like the factory loaded slug is better supported and less likely to expand,
due to the wad being forced further into the cavity of the slug.
