69 or 75 RMR 3GH on game?

Does anyone have any experience with the terminal ballistics of the 69 or 75gr RMR 3GH bullets on game, varmints, or predators etc? Any idea at fragmentation velocity threshold?

I would assume the jacket and lead hardness should give similar results to the 69MK or 77MK/75Horn?

Are the ogives secant or tangent? Estimate on meplat dia and depth from HP to the lead?

And yes I know the OTM / Match / MK type bullets are not designed for hunting. But…if these 69 or 75gr 3GH bullets perform anything like the Scenar\’s and MK\’s in external and terminal ballistics then I may have to give 500 or each a try.

Any experience would be greatly appreciated!
