[QUOTE="Broz, post: 1132407, member: 7503"] Do your own research and choose wisely. As for me I am done with 7's as of a few weeks ago. I have used them in many shapes and forms for many years. Have taken many elk with the 195's from the 7-300 this year and an antelope. Many elk in the past with 168's and 180's in fragmenting and controlled expansion offerings. So far this year I have been there, (along side the rifles) and for the field dressing, of close to 40 elk. Most taken with my rifles. 7mm's, 300's and .338's. I have seen over and over what happens when the shot placement is a little off. I now know for myself what I truly believe to be truth in this matter. Not internet hype, or jabber from fans from any given caliber, but what I have seen repeatedly for years and proven to myself for the last time this season. When similar heavy for caliber bullets are used, 30 cals kill better and quicker than 7's, and a good 338 will trump them both in ballistics and terminal performance. Ballistic performance boils down to BC and velocity. Bigger higher BC bullets propelled at similar velocities will always end up with less drift, retain more velocity and arrive with more energy at some point. This is why the big 338's will trump 7's and 30's when all are loaded in the case to make them excel, and why bigger will go farther and do more work. My medium bore magnum is now exclusively my 300 win with a 215 Berger at 3035 fps. It has shown me over and over how it will kill better than the 7's when point of impact is a little off. If I want to kill quicker and go farther than the 300 win. I will use my 338 Terminator. May not be what some people want to hear. But this is 100% my opinion with 100's of elk kills in the last several seasons and documented results. As for twist, I have used 9.25 to 1, many 9 to 1's, some 8.5 to 1's and some 8 to 1's in the 7's. I recommend you go with the 8 to 1. It will get you all the BC your bullets have to offer and keep it for farther. I only wish I could show you for yourself what my eyes have seen this season with the 40 elk we have killed so far. Taking a 30 and a 338 to kill some more tomorrow if the weather permits. Good luck in with whatever you choose. Jeff [/QUOTE]
