Sorry. Out of curiosity, I have modelled this in QuickLoad...

Using my own results as baseline: weighting factor set to 0.42, from a 24" tube, it reckoned I'd get ~2876fps and 57.7k psi. The labradar I borrowed said 2860fps, so I'm pretty confident QL is matching up with reality pretty darn well.

I don't know your OAL so assuming closer to a book value of 2.900". With a 200 ELD-X, it reckons you need 73.5gr to get to 3111fps (and 72.7k psi to boot).

But you're only using 69gr? That only gives 2913fps according to its estimate. The only way I can get it to line up with your chrono result is by changing the burn rate of the powder and making it quite a bit faster - 0.3397 to 0.3975. That gives exactly 3112fps but... wait for it... 83.2k psi.

Knowing that there's no free lunch and that speed and pressure go hand in hand, I would be wary of continuing to shoot that load.
