The standardized gel/barrier tests, with the gel blocks carefully prepared and checked with a calibration BB shot, offer a way to make comparisons based upon similar circumstances.
The use of other simulant "mediums" (than 10% gel) may offer a certain ease and convenience to the lay person interested in engaging in some informal "testing", but how are the results observed in the use of such simulant mediums when it comes to having a correlation to the results observed in actual shootings?
The standardized 10% gel formula (again, properly prepared & checked for 'calibration') have been demonstrated to have a correlation with observed results obtained in real shootings.
