220 gr plated 10mm starting load
I got a great deal on several thousand 220 grain 10mm/.40 plated round nose bullets. Only trouble is, there is no published load data that I can find for it.
I load a lot of 200 grain 10mm loads with my mild loads around 1,150 fps from a 5" barrel and my wild loads around 1,275 from a 5" barrel (this is a very hot load and only used in new brass with fully supported chamber). I use hodgdon longshot for the hot loads and HS-6 for my milder loads. Again, however, I find no published data for the 220. My initial thought is to take the 200 grain longshot starting load, reduce by 10%, and do a full workup in new brass. I might also try AA#9 for this since it is a bit slower than long shot (and do the same -10% from the 200 gr starting load and workup). I will also be shooting these in my cmmg 10mm 8" banshee AR. Any experience with this weight of bullet would help. Thanks |

Great link. Now I have more information for the different bullet weights that are not in my reloading books.
