[QUOTE="Darryl Cassel, post: 7879, member: 34"] VH As per the Oehler Ballistics program which I feel is one of the best and closest to actual BCs. Sierra MK 107 Gr 6mm----.555BC Sierra 80 Gr MK 224 bullet---.420 These BCs fall in line with what I have found to be true in actual fire situations using both bullets in my 22/284, 6/284 and my 243 with a 30" barrels and 8 twists. I to am fond of my 22/284 but the fact remains, the 6/284 and the 243 at extended range is much more consistant and produces less throat eroasion then the 224 bullet does at high velocity, especially 3500, to 3600 Fps. Many high velocity 22s are shot out in 600 rounds or less. I know of one that was gone at 400 rounds. As mentioned, if the 80 gr 224 was so good, it would be used and winning 1000 yard matches consistanly but, it don't. That's why I agreed with another poster that the 243 would be a good choice for his P-Dog shooting out to 1000 yards, plus a bit. If I'm going to shoot 500 rounds per day (or more) at 800 to 1000 yards, I'll take the 243 with a 30" barrel and 8 twist shooting the 105 or 107 gr bullets.
