10mm hollow point identification?

[H_G]

I don't know exactly what these are so I'll do my best to describe them.:banghead:

Headstamp is R-P (remington?)
Casing is nickle-plated brass.
Bullets look nickle plated. They have the grooves fro "petal-ing" The
The primer is the same color as the casing.

I got 50 of these for 15$.


Any help would be appreciated. I've been cruising MidwayUSA and CTD's website with no luck.

Thanks

Sounds like someones reloads to me. Those "nickle plated" looking bullets could be the 175 Gr aluminum jacketed Winchester Silver Tip.

Without pictures it's going to be hard to tell. Although the bullets being silverish I would guess reloaded Winchester Silvertips in Remington cases.

The guy I bought them from said they were factory, he had 6 more boxes of them sitting there.

In the case they were reloads, you think I could still use them?
