Yeah it's gonna come out the first hole made. When the bullet hits the water jugs it slows the bullet and it takes longer to get through it, so it would mostly come out the front. Kinda wierd huh, you think it would be blown out the back. but that's science!
With a can it doesn't slow the bullet that much so it look like it just explodes. But if you slow it down you can see it come out the front first.
Hwy 410 is quiet a drive for me.
The place I go, and will be this weekend is up on Mt. Pillchuck road. Off of Mountain Loop Hwy outside of Granite Falls. About 2 miles from the top and .25 miles off the main road is a pit that goes about 75 yards. Surrounded by 50 ft rock walls so it's pretty much safe to shoot anything thats not real big.
