That their bullets do better with a jump to the lands and that they also MUST be coming out of the barrel at LEAST 3,000fps to even stabilize which is my thin line of margin with my 26" 1-10" twist barrel!!! I have got to burn it hot to get that magical 3,000 mark. They told me their bullets are not designed to be shot or zeroed at 100 yards that they won't group that well that close because they haven't had enough time to "equalize' yet. That all of their personal guns are zeroed at three hundred and that their bullets are designed to be shot to the MOST EXTREME ranges possible! They are using the same bullet design as Cheyanne Tactical (i.e. CheyTac) in their .408 CheyTac cartridge that is designed to be shot at up to 2,200 meters!!!! Thanks guys for taking the time to read my long post and as always thank a vet, keep it safe, and send em down range!</p></blockquote><p></p>
[QUOTE="tacsniper0888, post: 676531, member: 51520"] Hey guys. I'm new here but I'm wondering the same thing. I can't pull up the excel spreadsheets or jpegs on my phone and I don't have a computer. Just my iPhone. The joys of sophisticated technology I guess. I also have a .338 win nag in a Remington 700 Sendero which ad many of you probably know is their top of the line over the counter rifle. Anything more is custom shop. It has an H-S Precision pillar bedded stock on it and a 26" fluted heavy "magnum" contour barrel on it. I want to e able to effectively and accurately shoot at LEAST 1,000 yards with it and be able to kill whitetail. I have a Millett LRS-1 6-25X56mm scope on it with 120 moa of adjustment vertical and horizontal with a one piece Millett 20moa scope base.
