7.62×39 Brown Bear hollow point test results

I tested this round in numerous videos over time. It has been tested for expansion in Ballistic Gel, Water, and Pizza Dough with varying results. It exhibited good expansion in water, but no expansion in 2 out of 3 calibrated ballistic gel, which is concerning. These tests are documented in the videos below.

It would appear that the Bear branded hollow point rounds require something less viscous than ballistics gel to expand. I base this on the fact it expanded nicely in the water test while the same ammo batch failed to expand in ballistics gel 66% of the time. I would hypothesize that since other brands expanded well in this gel that this Bear ammo is simply not very sensitive to high viscosity materials and, as a result, offers limited performance.

Ballistics gel is designed to mimic swine tissue, which resembles the consistency of human muscle.

From what I can tell Golden Bear, Brown Bear, and Silver Bear are all the same except the finish of the steel cartridge case. Polymer Coated, Brass Plated, and Zinc plated respectively. In other words Brown bear hollow points should be the same as Golden bear hollow points, etc.
