Home Forums Reloading Bullet Casting Hard Cast Bullet Expectations

This is the best place I can think of to ask a question in regards to hard cast bullets.

I don't cast mine own, yet. So I bought some from Double Tap for my 40 S&W. They are 200 grain bullets.

I shot some into some wet media yesterday and came up with these results. I shot them from 15' at
975 to 990 fps mv.

The bullet penetrated about 6" and
came out weighing 104 grains. Nearly half of its weight lost.

I would have thought these hardcast bullets would have given me more penetration and not lost so much weight. I noticed tiny bullet pieces in the paper I shot into. Like the bullets came apart.

Posting a pic here gives you an idea of what it looks like.

Is this to be expected from a hardcast bullet? Me thinks not?

What say you men of experience here?
Is this normal results?
