Start saving your milkjugs and stacking newspapers vertically in a carboard box. By spring you'll have enough milkjugs and your newspaper catch box will be full(not phonebook tight, but tight). You want the newspaper to catch the expended bullet, have the water mushroom the bullet.
Fill milkjugs with water and put them in a row with the cardboard box at the end. Takes a little trial and error to find how many milkjugs in a row to slow the bullet and catch it in the newspaper. (I used two sawhorses with a 2 X 8 between them right in front of my target). We shot anywhere from 40 to 100yds from the miljug line depending on calibre (speed/energy)
I suspect you'll be surprised at some of the results. We tried it with different calibres and different bullets. Learned an awful lot about how bullets react, how different brands of bullets perform, plus it was fun. Because of our testing we actually quit using one brand of bullet I had hunted with for decades. (proof positive it comes to shot placement, 'cause every bullet of that brand we tested failed miserably)
Once we tried making our own ballistic gell out of grape jelly mix instead of a newspaper box. Lol, you wouldn't believe how far that grape jelly spread on the white snow.
Just remember not to hurry to dig the bullet out of the newspaper, Hot!. I weighed the bullets and measured the diameter to see the weight retention and spread.
If I remember right it took anywhere between 4(30-30) to 8(450marlin or 300wm) jugs but don't quote me, it's been a few years.
