I have a "few" 10mm... [even a revolver]
I would suggest a "Hard Cast" boolet of 180 to 200 gr..
or an FMJ [real one not coated] at 180gr.
I am not a fan of heaver than about 210 gr in the 10mm as speeds will be a little slow.
The old Keith loading for the 44 spec is a good example.
245 gr long nose at 1100 to 1200 fps.
For the 10mm , a 200 to 210 Cast boolet with a flat on the nose
of about 64% to 70% of diam and a S.D. of about .180 to .188.[see mountain molds for specs]
Speed of 1100 to 1200.
As Keith put a 44 through a deer sideways at about 600 yds,,,
I doubt you would need more.
