[QUOTE="rdsii64, post: 1093003, member: 13978"] First I will say if someone told me what I'm about to tell you, I wouldn't believe it without proof. In fact I saw it with my own eyes and I'm still not sure I believe it. Anyway, My fathers day present to my self was a magnitospeed sporter. Yesterday I took it along with my coyote rig (which is a RRA 20" predator pursuit) to get some chrono data for my goto load I worked up before I owned a chrono. I shot a 40 round string over my new magnitospeed. With a 20 inch barrel launching a 77 grain bullet, I would have been happy with 2700 FPS. Now comes the part you may not believe. (hell I saw it and I'm still not sure I believe it). The average MV for those 40 rounds was 2908 FPS!! Now let that sink in for a minute. 2908 FPS FROM A 20 INCH SEMI AUTO SHOOTING A 77 GRAIN BULLET WITH NO PRESSURE SIGNS !!!! I will say this load is hard on brass. I'll shoot a piece of brass 4 times then toss it. Anyway, I'm pretty stoked about the data I collected. I also chronographed my new 308 AR but that another post. Coyotes beware, [/QUOTE]
