[QUOTE="Kevin, post: 26496, member: 603"] I know what you are talking about. This is just my opinion, and what I have observed, so make what you want of it. In my 220 swift AI, 16 twist, I shoot a 55gr BT or 55gr. V-max at about 4250fps. At 100 yards my average group size is only 1.25 inches. If I move back to 500 yards, groups are no greater that 4 inches and often less, around 3 inches. Based on the 1.25 inch 100 yard groups my 500 yard groups should be over 6 inches. (glad they are not) I believe that these bullets are just on the verge of being stable and right out of the muzzle get kicked slightly to one direction or the other then continue on a parralell path relative to the barrel direction. So call BS or what ever you want but thats my .02. Other opinions welcome. [/QUOTE]
