The Nosler .40's are lighter constructed than the XTP's.
The 180gr XTP's are constructed (rated @ higher velocity) than the 200gr's. But you have 10% more mass with the 200grs.
Some of the "specialty" loaders might not perform to spec in the G29 barrel length.
Another option is using Hornady HAP bullets. They are XTP's without the nose serrations.
It is tough to beat any of the hard cast listed here. You want penetration, use the hard cast with large meplate. Test for function in your gun.
If you are talking Griz, use something else.
