Fun with ice.

[Messy bear]

We now have enough ice for ice testing as I call it. Shot some cast bullets into ice today for recovery. Works good if alloy and speed are compatible. They come out about perfect! Can't tell from water sometimes.

Very interesting!

[Beerd]

pictures?

[rking22]

way Bach when things were simple... good friend and I had a ball riding around shooting icicles that hung on cliff faces around here. We had permission to hunt on all the farms along there, good days. Anyhow we used Win 94s and 311410 cast from rim fire bullets powered by Herco. Really miss those days.

A friend and I used to take his moms dishes, line them up on the deck railing and pour some water into them. The ice would slide right off them in a few hours and make great targets.
We would have a pile of them stuck in the snow for the weekend. Great targets and no cleanup.

[Messy bear]

Those ice targets sound fun! I was just shooting into ice in a pond. It's interesting that they come out looking perfect! Don't have pix as I have dumb phone but nothing too complicated. Just blast the ice and get showered with chunks and dig it out.

I like that idea. You could add food coloring for a variety.

I just watched a video on YouTube, where a couple of young guys were shooting, I think 9mm into the ice of a frozen lake. They filmed one of the jacketed bullets spinning and spinning on the ice. It was interesting. I didn’t think to save where it was. Did anyone else see it and want to post the link?

Here it is.

I don't shoot ice targets anymore, at least with jacketed ammo.

Just a couple inches of ice will certainly stop a bullet in it's tracks, and leave it lying right by where it impacted often times, but the richochetts were really something else. I've shot at some questionable targets before, but that mad whizzing and whirling made me think twice about doing that again.

Definetly didn't help we were using steel core.

The appeal of just freezing some water in containers with some food colouring is obvious, close to free and no cleanup, but I got scared off, heh.

[bmortell]

seems odd it can catch bullets without damaging them more than water, would like to see pics if possible

Someone on this site told of shooting into a snowbank. After the snow melted, the boolits were pristine and just laying on the ground.

You guys aren't from Texas.

No they surely aren't from TX.

I do it all the time, in spring it's like treasure, lol. Shooting into ice is dangerous, frozen trees is just as dangerous. We would shoot icicles with our bb guns to bring them down and make places safer. When I was a young boy a few older guys had a box full of peat and sawdust to recover bullets, fmjs and AP would always go right through and were never recovered. I seen mythbusters shot ice to see the spinning bullet effect.
Be well

With a bullet spinning that fast, I wonder if it gives a friction burn due to the spinning as it comes to a stop inside someone?
Thar is a lot of rpms here.
Over 88,000 rpm for a 9mm with a 1 in 9 twist(115 grain doing 1100fps).

Snow indeed does work that way. I find a ton of bullets every melt, my guess is even the ones that aren't outright stopped by the snow if there's not enough just glance off the frozen hard ground and end up sitting on the surface.

I don't believe the bullet is spinning that fast. If it could fly for a full minute it would rotate a total of 1400 times...over it's entire flight...it only turns once every 9 inches....so...for example if it hits a person...it would only rotate once from front to back if a person was 9" thick.

Check your arithmetic!

A bullet at 1000 FPS, in a 1 in 12 twist, spins at 1000 FPS, or 60000 rpm.

The rpm figure is like a snapshot for the moment.
It would make one turn in the 9 inches, but it also covers that distance very quickly.

Here's something kind of cool:
Another 'do the math' exercise that comes out with a interesting number is--- if a dragster's engine is turning 10,000 rpm--
on a 1/4 mile run it covers in 10 seconds, the crankshaft may only actually rotate a little less than 1000 or so times.

You are correct. I forgot to do the last step of the equation. It should have been 88,000. I will correct the first post.

actually, even with the corrected value of 88,000 rpm, that value isn't too high. high speed medical and dental drills run at those speeds all the time, for hours on end, whereas a bullet RARELY has a full minute time of flight, and that would NEVER be a 9mm handgun.

[Messy bear]

Wish I had pix. Maybe get some done sometime. They look like they come out of water if impact veocity isn't too much for alloy.

Only two pristine ones, the rest hit wood.
Hope to find more next thaw.

Reload that blue one. The one stuck in the tree,again!!!!!:kidding:

The bullet is only turning 1:9 as it leaves the barrel. As the velocity drops the rpm remains pretty much the same so when the velocity had dropped in half the bullet will be turning close to 1:4.5. (Crude example)

A top fuel dragster will cover the 1000 feet (no longer 1/4 mile for top fuel and funny cars) in about 3.8 seconds and average around 8000 rpm so they only turn about 500 revolutions not accounting for the time the clutch is slipping prior to lockup. That 500 revolutions costs somewhere around $6000.00 in tire wear, an engine rebuild, 18 gallons of nitromethane and labor costs.

Frozen trees, oh my!! In my misspent youth, I fired a .69 cal flintlock pistol at a target on a frozen oak tree. That ball came straight back between the eyes. My head is hard, no real damage but wow, what a headache for a week. That and explaining to your parents how you did it.….……………….

Friend of mine was walking the woods with his kids. The kid shot at a frozen oak tree 40 yards out and the bullet came back and hit him in the zipper. They picked the bullet up off the crusted snow they were walking on. Yep don’t shoot trees in the winter, they make bad back stops.
