I have heard that you can use wet phone books or newspaper to test penetration. Is there some kind of chart to show you the difference say between the ballistics of the phone books and ballistic gel ?
I've done some penetration tests using 1 gallon plastic milk jugs lined-up and filled w/ water. As a point of reference: My 8mm mauser penetrates 6 jugs, each approximately 6" across, with a 220 grain bullet.Thanks you guys. Been trying to test a .44 mag with 255K bullet over 22 grains of 2400 and they just go through everything .. I like that carton idea. Do you have any idea how to figure out how many carton to a inch-foot of penetration ?
Here is info on gallon water jugs from Gun Tests - they deduct 10% from width of water jug.Thanks for the information and a question......any idea why plastic isn't usuable?
"gather several (and we mean several -- about 30) cardboard half-gallon milk cartons (plastic won't do)."
