real life power/impact results

[longislandhunter]

Sounds like a good possibility Jim, good idea.  Certainly is something available to everyone and counting the pages of penetration is an easy, consistent manner of documenting the results.  I think we should definitely put that on the list of options.  Lets see how the others feel about it.

Some test are done using swine carcases since they simulate flesh,muscle and bone of some test done. But I realize that we all dont have a side of pork hanging in our shop's hehe. My dad's got some out on his farm but I dont think that he would let me perform these test on em hehe. I also have friend who work's in a meat department hmmm. Save your dinner bone's, pour your jello mold's and insert the bones just before it set's up.? Just throwing out some idea's. Ed

There's alway "roadkill"  :)

It's free, usually in good supply, your actually doing the public a service by removing it from the roadways and it's the "real thing".  :)

I know, I know,,,,,, but I'm just throwing it out there  :)

I think that if we did a jello test that it would be a best case senario to the pellet performance. With adding bones I think it would be a cool factor to say it blew through it. but its to inconsistant of a variable and not really repeteable. And also I dont know about eeryone else but im shure after jeff makes his kills he still has the fur laying around? Maybe you could lay that over the entrance to the gel to get sumwhat of a simulation of it punching through the fur/hide.

how about multiple tests (ie Gamo 440 with tomahawk shot into electrician putty and quarter inch plywood) now this does not simulate flesh or bone but we can gauge the successes from the failures.

How about a leather work glove ( like the brand Mule) with a bar of soap in it. Maybe also wrapped in a rag.

You know I was thinking in the same manner. I got some deer leather and was thinking of trying it for a outer skin. Ed

Jeff posted this link on the Air Gun Gate, but I think this would be a nice, consistent way to do penetration testing.  I think Duct Seal is cheaper than plumbers putty, and a little stiffer.  Not a true flesh sim, but at least we could all have a consistent ballistic medium, without having to cook it up ourselves.  Not sure what to do about the "fur and feathers" part.  I'm not a hunter, so I gotta ask, just how tough is a critters hide?  I know the hunters talk about tough skinned game, but is it really that, or just some critters have a much stronger will to live?  For simulating a head (skull bone) shot, I think the above with a THIN (1/8") something in front would be reasonable.  I'm thinking door skin or Masonite, the stuff peg board's made of.  Readily available, not too expensive, and should be pretty consistent across the country.  Let me know what you think.

Thanks for the link Dave. :-) It was cool to see what happens to the pellet after impact.

Hey Dave,

Squirrels are the "toughest" skinned small game in my neck of the woods.  Their hide really is pretty tough.  A pellet, .22 or .177, can and does of course penetrate it but it's definitely tough.  A rabbit on the other hand is just the opposite.  Their skin is very  soft, probably one of the easiest small game animals to skin for the same reason.  The only other animal I can think of that is really pretty tough skinned, small game wise, is a woodchuck.  

As for a material that could be placed in front of the putty to simulate skin I had a thought,,,, how about one of those "chamois" cloths (don't know if I spelled that right)  ?  You know,,, one of those thin leather like sheets that you use to wipe the residual water off your car after you wash it so you don't have water bead marks or streaks on your car?    They are available at any auto parts store or Walmart, etc.   They would be easy to place and secure in front of, or over, the putty you're shooting into, and they are relatively cheap.  Not quite sure how such a material would hold up to repeated shots, but it might work.  

I don't know, it was just a thought, what do ya think?

This thread will probably grab the attention of our government.
"Hey boys, these air rifle guys are trying to simulate what happens when you shoot a pellet into a poor forest creature."
"So.."
"Maybe we should hijack their data and submit it as our findings. Save us allot of time."
"Cool. Can I be home by dinner?"

[Knighticus]

oops..

So they really are tough, not just tenacious.  Good to know.  Oddly enough, there are very few grey squirrels around here.  Mostly we have the smaller Douglas squirrel, usually red, sometimes black, and the much smaller Golden Mantled ground squirrel, usually misidentified as chipmunks.  The latter get thick as flies at times.

Sounds like the chamois would be a good option.  It's actually the skin of a small mountain goat type critter, so it is leather rather than leather like :-)!  Geez, you'd think I was teaching a course in natural history or something.  They do have synthetic chamois, I think we'd want the real thing.  Sounds like we're almost there.  Later.
