The "ratio" is one "milk carton" equals 2.5 inches of ballistic gelatin.
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)."
