Was wondering about jackhammers lo velocity operating speed, and whether or not they lose petals or shed the Petals, because I haven't been able to find too much information about them
These are .429 cal 205gr jackhammer. Basically 100% weight retention. These were shot into 5gal water jugs. One on the left was a simulation if the load on the right was shot @ approx. 80 yards. Leaves a nice bore diameter wad cutter meplat.
