Drywall Penetration Test 6-116 Joules, 43 50 68 cal (Are Your Neighbors Safe?) 

We test and HDR50, HDR68, HDP50, Glock 17, and M17, we start with co2 glock 43 cal and use 12g co2 in the hdr68 and hdp50 then move up to the higher joules, we found that even a modded hdr or hdp with co2 can shoot through the wall of a townhouse, apt and bungalow, then we move up to the higher joules, similar to a 22 cal power, also the reason why the hdr68 didnt do so well with co2 is because the grimburg juls are to tight in the barrel i come to find out after the test, to much friction drag, also i was using 8g steel balls in the hdp50 so they were to small for the bore and lost power, i have many vids showing much better numbers, i should have used the 12.7mm 8.4g balls cuz they fit the brass barrel better
