[QUOTE="JeffVN, post: 366391, member: 2261"] I've got a 7/338 Norma Mag being built right now - actually long overdue but that is a different story. If you put a long enough barrel on them 3,300 seems like its easily in reach...especailly at any altitude at all. As for teh 7mm Berger 180s hldoing together at 3,300 fps, I think the original ones (thin jackets also now called hunting) have no chance of doing it; the new thick jackets (also called target) may or they may not....3,300 is pretty spicy, and approximatley where the various jacketed 338s start to tear themselves apart (at least the Sierra do from what I've been told). I did talk with Bob Cauterucio about his 189 grain 7mm (purported bc of .725+) and he said his will do close to 3,300 fps. He uses a thicker jacket for his than Berger used to use. How they hold up when compared with the newer Target Berger's I do not know. But i will when my rifle gets delivered, as i have 2,000 of Bob's 189s and several thouseand of teh Berger 180s (I use them in my7WSM F-CLass rig) JeffVN [/QUOTE]
