Be 86 and 200 grain herd cast 10mm

[jtwodogs]

Alliant reloading data does not list loads for 10mm 200 grain hard cast bullet.
Yet I have heard so many using that very load without listing their data but very accurate.
Any have any real world data?
Thanks

I started using BE-86 when looking for 45 ACP+P loads for a UZI it just would not run the load I found to be the best was 200 grain lee cast wheel weights and 7.3 grains BE-86 from a 16-inch barrel 1227 FPS and accurate.

I have never loaded 10 MM I do think you are heading in the right direction. The people I know that shoot 10 mm are scared to death of cast bullets.

Alliant does show a max load of 7.6 grains for a 190 grain JHP, so that's not too far off and should be a good reference point. I think based on that, if it were me I might start with 6.5 grains with a 200 grain cast bullet.

It does matter though whether your gun has good chamber support, so you should verify that.

Shooting kkm barrel in my glock, and my desert eagle 1911 10mm I believe has a fully supported chamber
