G'Day Fella's,

Rolf, getting bullets that are specifically designed to expand at 2000 and 3000fps, to expand at 1000fps or less, is a major problem!
This problem has brought some promising new bullet manufactures (I can't remember their name?), into the market place but I'm not totally convinced of these bullets viability, in a conventional Hunting situation!

In my experience with Sub-Sonic ammo in a conventional hunting situation, I'm left believing you still need to aim for either the Brain ("Australian Heart Shot"), or a Spine shot on these Game animals (Deer, Pigs etc)! As we all know, this is not always an option, as most Game animals don't cooperate that way, in bringing about their own demise.

FYI, I have had an initial play with casting up soft lead bullets and then coating them with Powder Coating material. This gives you a very soft bullet, that you should be able to safely run at 1000fps, and when it makes contact with the Heart-Lung area of a Game animal, the bullet should expand.
Unfortunately, I've not had the time to put this theory into practice, as I'm been to busy addressing more important things in my life!

I have also set up conventional hunting bullets in my lathe, and machined weakening grooves in the nose area of their jacket. In theory again, this "MAY" weaken the jacket and "MAY" promote expansion at lower velocities but................... it is still just a theory at present!!!

Hope that helps

Doh!
