It's really hard to tell.So guys...the one picture that shows a decent group with a bad vertical flyer (not sure if its actually a flyer or flinch or whatever) ...what are your thoughts? Can a bad load cause 3 out of 4 shots to group well or is it more likely something is going on with me flinching or my scope not holding zero?
My personal opinion is that you do not have the load tuned yet. I would set the bullet at about .015" jump and do a powder ladder test on the upper half of your charge range. For example if the book lists 42-50 grains, then I would load two shots at 46 grains to 50 grains in half grain increments. Shoot them at the 300 yards you have available. The charges that are near an accuracy node will have impacts closer together than the rest. I then latke the best load and will load 3 more 2 shot groups. One at the load already shot and one .2 grains on either side of it. Take the best charge of those and start working with the seating depth. I'll move the depth .01" at a time until I get the group under an inch then I'll move .003" at a time.
Others have different methods, this is how I do it. Works for me. I don't think you are very close to having the load tuned.

Off of the top of my head reading through the whole thing my guess is that it's either a busted scope or you are flinching.
Hmmmm, you eliminated the Leadsled, you checked the tightness of the scope mounts, you verified the action screws and you feel confident that it is not you.
Ony suggestions at this point is to let someone else shoot it and see what results that my be produced for comparison, try a different projectile and have a competent smith boroscope the barrel
By the way, what is the make and model of the rifle?
I tend to agree. As other posters have stated, you probably have some load tuning to do. With that said, I would be very surprised if minor differences in seating depth or powder charge took you from sub-MOA to 3-4 MOA at 100yds. When I do max-charge work-ups over the chrony at 100 yds, I generally get 3" spreads in POI over a 250 fps velocity range (from rifles that shoot).
I've had rifles that despise a specific bullet, and changing it made huge differences in accuracy. Other than that, ladder testing for powder charge and seating depth (while very useful for tuning a load) typically have given me incremental improvement (taking out a half MOA here, a quarter MOA there, etc).
I would fully eliminate equipment and form issues as potential contributors before fooling too much with the load. I can say from experience nothing is more frustrating than trying to chase down that perfect load when there is noise from some other issue stinking up your data. It leads to useless powder burned and lots of frustration.

Good plan. Until you can completely eliminate equipment and form issues all you are going to do is get more frustrated. You can't tune a load if the setup and shooting mechanics are not right.The key here is that I am working up a load so I believe it is down to either the load is bad OR I broke my scope using the lead sled because as you stated I eliminated the sled from the equation by shooting the same loads off of my other set-up and getting similar results. This is a remington 700 mountain SS in 3006. I do have another scope so what I think I might do is load up the same loads I did yesterday. Throw on that other scope, and if I get similar results I know it is the loads, if suddenly the groups are great, I know it is the scope.
