    I just purchased 220 grain (10mm) plated bullets and can\’t find much info for load data. I can use the data provided for cast bullets but I don\’t know how much to increase the powder load. I could use some help.

    I bought the same bullets and was told to use the load data for 200 grain and reduce it by .2 – .3 grains. So, I\’m trying Accurate #9 from 10.5 grains to 12.3 grains.

    Testing them out tomorrow so will check back.

    Range results were very favorable. Did a video of the results on Youtube…

    Thank you for the info. I will be shooting mine through a Rock Island (Gov. model) 1911 w/5 inch barrel.
    Just have to locate some Accurate No. 9 powder.

    Have you any additional load data to share on these 220 grain RMR bullets? Not having much luck finding any #9 powder.
