CMMG Banshee 45 ACP 5 Inch Barrel Anyone have a pet load?

[BarnDweller]

I have been trying to work up a load and am not having any luck. Yes I have manuals and have used data from the Manuals.
I can not get it to group better than 5 inches. I have worked up ladder loads starting at starting load and going up at .1 grain all the way to max load. I have tried FMJ and Lead bullets (all 230 grain).

I have never had a gun I could not get to group (yes the red dot is tight and not moving).

I have some 200 grain plated bullets ordered.

Thanks for any help anyone can send my way.

What groups does it shoot with factory ammo?
