[QUOTE="eddybo, post: 478706, member: 7194"] Using G1 BCs and shooting at extreme velocities, might fall on your list somewhere. BTW you might make light of actually matching actual trajectories, but there are a lot of specialty bullets out there with no actual BC data available. I have been faced with that situation a few of times. Even with my jerry rigged data I have made 1K+ shots in 5 states. In one instance actual G1 BC data later became available for a bullet I was shooting with no previous data. When I introduced this new actual and probably very correct BC data into the mix that is when the problems began. I have started from square one a couple of tiimes on that rifle, a 338AM with a NXS trying to fix what I perceive to be a problem. I have yet to to find an answer. I would however wager that there are not many rifles that that will more reliably hit targets at 1K plus yardages, even though my drops are jerry rigged from actually shooting the rifle and not theories. Sometimes you have to bring mohammad to the mountain because the drops are what the drops are and changing BC or velocity or any thing else in your ballistic computer are going to change the actual drops shot on a single tall target moving back and shooting at increasingly longer ranges using a single POA. I still have never seen a G7 BC for that particular bullet. I find it disturbing that on the dozen or more rifles I shoot at long range that I do not have similar problems other than the occassional anomaly which is usually correctable with a velocity adjustment. When I say anomaly I mean that the BC for one bullet may work perfectly while another bullet in the same rifle may wander from it's anticipated path. Considering only vertical you can get within MOA on a 800 yard target on any given day with nothing but a BC (even a G1 BC) and a velocity estimate from quickload, not even a real chrono reading. It is only when you move into real long range or real accuracy that you have any real problems from most of the items on your list, but they do become very important. I took a long break from this site a couple years ago. I chose to not spend time here everyday posting when I could be out shooting, or building guns, choosing only to pop in occassionally to lurk but rarely post. I also stopped posting my hunts at that time. Participating in threads like this one and the BC thread may have been part of the reason I left in the first place.
