Hi Pug,
I have to go by the manufacture's description as I have not yet seen a die. The jackets that I have now,are the ogive serration design.
The ogive serration die can be adjusted for both length of cut and depth.The full length serrator can be adjusted for depth but not length.As it's name suggests, she's all the way or nothing.
I believe what is needed for your needs perhaps will be a tapered jacket,with a full length serration.With the heavy shank section,the bullet should expand about 2x diameter untill it hits the heavy part of the jacket, at which point expansion should be over.This is in therory. The real world will be test media and actual testing on flesh and bone.
wow, can't wait to see the results with this test, exciting! good to see you over here richard. I wonder what's in Fort Shaw, besides the one and only mr allen!
have heard nothing but good about this guy, and sure am glad you're working on this, thanks!
I was thinking back on Artful's post about standardizing test media and since ballistic gel is still high as the devil I thought I would mention the bullet trap I use. About $20 bucks to build and it is replenishable and works fairly well as long as you don't miss to many times :). Make a 3/8" thick plywood platform 2' by 3'. On this mount two 1' by 2' 3/8" wood runners about 5 1/2" apart using steel shelving brackets. Place a leaf trashbag down between the runners and then fold it back down around the outside of the runners. Badsically now you have a wood frame with a thin plastic liner. Insert six paper towel rolls into the frame standing them on end and then fill with water. You will get about 30" of media. You fire length wise at the frame through the liner. It is also a good idea to put poles on all four corners so you can align yourself with the frame. Gives about a 5" by 11" firing window and doesn't leak as bad as you would think. The recovered bullets don't seem to care whether you use Brawny or Bounty. Also the trash bags with the carry straps all the way around the rim work best as they provide reinforement when you add the water.
It was interesting to see a 1600 fps whisper bullet penetrate 26" and expand over 2x at 50 yds yet a 955 fps bullet of the same design completely went through the test box and almost through the 1/2" backstop that I happen to put up. Its expansion was about 1.7x but probably caused most by striking the backstop board.
OK so what happened to all the momentum of this thread and testing and results and such. I really like the sound of serrated jackets and massive expansion or fragmentation either one I am not picky.
Anyone test these bullets were the results pro or back to the drawing board?
I'm a whisper shooter who has a couple of thousand 240 SMK's. No there not for sale but reading this thread has me interested in a heavy bullet that will expend as opposed to doing the yawl thing. If you guys figure out something that shoots well and expands count me in... I have a herd of deer to test them on...
Throw my name in the hat for wanting to try and buy some of the "new" creations.
Either the heavy, i.e. 300 gr. or the serrated tip hollow points in 240 gr sounds peachy and I too have an ever expanding herd of whitetails that needs culling.
I know heavy sounds good but in order for a hollow point to work it has to go straight in and my 1:8 at subsonic velocities doesn't like bullets over 200 grains. If you are shooting 100 yards or less this type broad nose hollow point has shown some promise and I have located some similar 180 gr bullets that have a serrated jacket and just need to be hollow pointed. Changing jobs, losing the use of a big lathe and finishing up a lot of little projects has put a lot of the testing on the back burner but I will let you know if anything really useful shows itself.
So did we find some interesting bullets or not? Looks like things just petered out. I was getting excited about the Aluminum tips and stuff.
I'd be happy to test here in Central TX where the weather is always good for shootin'. My whisper barrel is on the way, but downloaded 308 win can easily duplicate velocity.
This was added to another subject earlier. Wildcat Bullets has been sold. The new owners contacted me this week and said they would be up and running this summer and hopefully they would have the 300 whisper bullet going by then....We can hope!!!!
I hadn't seen this thread before, but like others here, I'm very interested. Just last night I was thinking that I'd seen some ads from EBR a while back about their subsonic 7.62x39 ("Jackhammer" I think). And I want to say that they featured a bullet that expanded at subsonic velocities.
I had been wondering if these were still being made, and thinking about pulling some bullets for use in the .300 Whisper.
Of course, they would either be slightly oversized for the bore, or would have to be swedged to .308".
