Comprehensive review of 9mm 108 grain Monolithic expanding copper defensive ammo from NORMA. Includes day/night shots, overview, chronograph velocities, 10% calibrated gel test with IWBA 4 layers denim, and summary.

Making the gel: Using Knox powder, mixed 18 oz per gallon of distilled water. Low boil at 130 to 140 degrees F. Used a painter drill bit for mixing. Pour into 18 x 8 x 8 stainless steel mold. Cool outdoors an hour or so to burn off steam. Store in refrigerator at 34 degrees F for 72 to 96 hours. When calibrating, steel BB at approx. 600 FPS at 10 feet. Acceptable range at block temp of 39 degrees is 3.25 to 3.75". Otherwise, the block is out of calibration.
