[QUOTE="BryanLitz, post: 628752, member: 7848"] The Gen II, thicker jacket has become the Tactical OTM, and is not recommended for hunting (although it's difficult for 300 grains of supersonic metal to [U]not[/U] be lethal). Nevertheless, we will be re-introducing the thinner jacket Gen I bullet with it's known upper pressure/velocity limit well understood and published, for those hunters who desire the rapid expansion characteristics of Berger Hunting bullets. These two bullets will be identical on the outside, the only difference being jacket thickness. Of course the hunting bullets will not be recommended for use in cartridges larger than .338 Lapua Mag because of the known structural limitations of that bullet. 0.005" isn't much, but considering the jacket is only ~0.025" thick; 0.005" is 20%. If I'm remembering my material-strength studies from college, structural integrety is proportional to the square (or cube...?) of thickness. In other words, the 20% thicker jacket could be more than 44% stronger which results in very significant differences in terminal performance. In addition to the above two bullets, there will also soon be a .338 SAAMI length Hunting Hybrid which, as the name implies, will be better suited for loading to magazine length. This bullet will have a shorter nose, and hence more drag and lower BC than the 'Optimized' hybrids. Of course these are necessary concessions to make for the sake of practicality. -Bryan [/QUOTE]
