I don't know about others but I am simply unsatisfied with the present state of terminal ballistic data on cast boolits. It's not that it's insufficient, it's that it is usually done with substitute mediums for real gelatin. Shooting milk jugs of water or wet newspaper is a waste of time IMO because deer are not made or jugs of water or wet newspaper/phonebooks. They are made of hydrated protein--gelatin.
Having now a hollopoint cast boolit mold I will be undertaking some experimentation and reporting back if there is anything worthwhile to report. I will also be doing testing verses the Hornady XTP JHP bullet.
I was curious if anyone has undertaken this sort of effort and if they have any pointers or recommendations.
My initial experiment will be in 357 magnum using the 359 Hammer Mihec mold loaded to ordinary book loads and shot out of a 5" 686 and a Marlin 1894c.
I am going to use unflavored gelatine and water to a concentration that will calibrate near FBI protocol using 17 caliber steel BB.
I have not yet decided if 4 layers of denim will be used or if I will use a layer of buckskin.
This effort will be undertaken at my own expense entirely for the benefit of myself and anyone else interested. Possibly it will be expanded to other calibers like 30-30, 44 Mag, etc.
Please make any suggestions in the comments. I have procured most of the necessary goods so far.
