Well, the weather was great the past few days, so I slipped out to the range to try out some new stuff..
This is the 64 gr. Speer Gold Dot offering in .223 that I have switched to for my patrol / entry rifle.
CCI lists the specs at 3000 fps (probably optimistic, especially out of a carbine). I don't have a chrono, though.
This stuff is brass-cased and the bullet itself is a boat-tail soft point. The propellant is a mix of ball and disc powders (don't know what kind).
The bullet was shot into water jugs from roughly 50 yards away. I recovered it in the fourth jug. It went through 3, into the 4th and dented the back of the fourth, which stopped it.
So roughly 24 inches of penetration in water. I read somewhere that water typically gives twice the penetration of gel, so I am thinking it would be aroung 12-13".
The load is a bonded 64 gr bullet. The recovered projectile weighed in at 56 gr, so roughly a 15% loss of mass. The recovered diameter is .529 at the widest part.
It held together very well though, and I am very impressed. I need to get a hold of a spare windshield to try these through....
Here are the pics...
