I have a couple boxes of Triton CQD 155gr. .45acp HPs. Never clocked 'em but they claim 1225 fps for them. They use some sort of sintered metal that does not contain lead and claim they are suitable for both training or defense use...probably the claim is correct. I have shot a few hundred on steel and they do break up well. There are several years old now and I seem to recall they were pretty pricey even then and at agency prices. Federal makes...or used to...a powdered zinc bullet for use in the 223 for steel type training and I have also shot a few of them, but they are also very expensive. Not sure who else is making anything now, but I'm sure it is out there.
BTW Triton's web address no longer works...don't know if they are still in business or not. They show a toll free phone number of: 800-861-3362...they are, or were, in Wappingers Falls, NY so maybe some of the NY crew may know about them.
