I bought my first .45 autoloader and am trying to match some factory speeds. I got and average of 839 fps out of some Blaser 230 fmj and an average of 828 out of Remington 230 HP. Tried getting to these numbers today using Hornady 230 gr hp, cci 300 primers and Unique. Started at 5 grains and worked my way up to 6.1 grains and the best average I can get is 784 fps. The last step from 5.9 to 6.1 only gained me a 1.4 fps on average. The good news is they all grouped very good. I am using a 5" S&W M&P. Have shot and reloaded wheel guns for years and never seemed to have this problem. This is my first venture into semi land! Any suggestions or favorite loads?
