UMP-45 | Bone Pile is one of 6 Mil-Spec Grade skins in the Operation Bravo Case. The Operation Bravo Case pays out Mil-Spec Grade tier 79.923% of the time (1 in 1.3), and DropLabz's model treats every skin in a tier as equally likely, so this skin's base chance is about 13.321% per opening (1 in 7.5).
The base chance is the probability the opening lands on this skin at all, before its wear is rolled and before the 10% StatTrak roll (this skin is StatTrak-eligible). It is not the chance of a particular wear or a specific float.
| Wear | Chance, given this skin | Snapshot price | StatTrak price |
|---|---|---|---|
| Factory New | 3.6% | $40.47 | $28.88 |
| Minimal Wear | 28.6% | $7.30 | $7.48 |
| Field-Tested | 67.9% | $6.06 | $7.25 |
Modeled wear chances assume uniform floats across the skin's range. They are not verified in-game wear rates; see the model assumptions and limitations. Prices are from a Steam Community Market snapshot dated Oct 27, 2026, 10:25 AM UTC; a dash means no price in the snapshot.
