They tend to loose the front core in real life hunting situations - much like a Partition does. And just like the Partition, that is what is the main source of energy transfer to the quarry. Because of the lost front core, their expanded diameter is not very large (even sometimes cylindrical), so they also tend to penetrate pretty deeply.

Daniel M. Thanks for the reply. As you can see, your the only responder! Probably due to very little experience in this country with these bullets. Also, thanks for the tip on the brass; I'll measure, weigh, and watch them real close. I have plenty of other brass, just thought I'd check these out.

Colt Here you have a section of the bullet.

and what do in gelatin

Excellent bullet a bit more expansive than partitions , very accurate , brass it's not what I like , RWS cases have the neck reamed , after five firings the cases stretch and the shoulder flow in the neck area , then you have a bulge , and usually a bit heavy than american brass , it means less internal capacity , weight it and if heavier than standard reduce your load .

Saludos

Has anybody had any experience with these bullets? I bought a box of RWS ammunition for my 300 Win. Mag. with 165 gr. Partition DK bullets. They are kind of wierd looking! I bought the ammo mainly to get the cases, but found out when I shot them they were very accurate in my gun (consistantly under 0.75). Have about 12 rounds left, and since they shoot so well, thought I'd use them for whitetail hunting the next few weeks. Anybody got any experience on the performance of these bullets? I recognize most any bullet will work on Michigan whitetails (50 to 150 yds.) but just curious!
