[QUOTE="Fiftydriver, post: 388917, member: 10"] BigBuck, I hear what your saying but I am not commenting on this shot as someone that has never shot at this range. I am commenting on this as someone that has EXTENSIVE long range ballistic testing experience with chamberings so far exceeding the performance of the weapon used in this instance that they are not even worth commenting about. Simply put and again, this is not opinion, this is fact, a bullet that drops out of super sonic velocity in flight will have severe if not complete stability failure. Depending on elevation, this will be from 1050 to 1100 fps. When I say a bullet will have stability failure, I mean it will not fly true and often times will tumble with no consistancy in any way. Even at very high elevation, super sonic velocity limits of this combo will be around 2200 yards. Again, I have tested the 338 Edge, 338 Lapua, 338 Kahn, 338 AX and 338 AM at ranges out to well past the super sonic velocity range of each of these chamberings. In every case, within 50 yards of predicted velocity drop below super sonic velocity, accuracy goes completely away. In most cases, bullets did not impact close enough to the target to even see where they impacted. If an occasional impact was seen, it would be very inconsistant and totally unpredictable as to where it would actually land, even 50 to 100 yards past the point where the bullet dropped out of super sonic velocity. The ONLY combo I have seen that remained accuracy and consistant, by that I mean better then 1 moa accuracy for groups at +2700 yards is my 338 Allen Magnum loaded with a 265 gr Aluminum tipped rebated Boattail at 3550 fps. Now this bullet has a BC of .9 so you can see the extreme increase in performance that this round has over the Lapua. Again, I am not saying anything against this because its to wild to be true and because I simply do not believe it can be done. I know exactly what happens when these bullets drop out of super sonic velocity. Would the bullet have enough energy to kill the target at this range, certainly and its totally possible that a kill was made but I have a very hard time accepting that three shots, three kills happened...... Even shooting out to 2000 yards would not raise any red flags by me because most any 338 Lapua load with a long range bullet would sustain super sonic velocity past 2000 yards and as such consistant bullet impact would be very practical.
