After years of testing Clear Ballistics gel, I have recently taken the plunge into trying my hand at real 10% ordinance gel.
I've picked up some gelatin from Walmart (the great value brand) and mixed it according to the FBI specs to get 10%. I let it sit in my fridge for 6 days, transported it to the range in a cooler with ice packs, set it up and shot a .177 BB over a chronograph at 606 fps. Unfortunately, it penetrated 4" which is a little deeper than the maximum 3.74" that calibrated gel is suppose to be at. I still shot it with HP ammo and recorded my results, but I wonder how close my results actually are.
My questions for those in the know: Is there a simple math formula to help me adjust my results to get more accurate data? Is there other over the counter gelatin that has the same bloom as true Knox or Vyse gelatin (I couldn't find the bloom for the Great Value brand)? Other tips to consider?
Thanks in advance.
