Nathan FosterRe: .22-243 load dataHI Chris, you can start with ADI 2209 (H4350) if you want to. This will cover all bullet weights without changing powders. with 55 grain bullets, sweet spots will probably be between 43 and 45gr 2209. Start at 41 grains as we have no history for the reamer.Add or remove 1 grain powder weight per 10 grains bullet weight when changing bullets. Example- 75 grain bullet, start load 39 grains 2209. Expected sweet spot at 41-43 grains. If you are going to run heavy bullets only, you might want to use ADI 2213sc for a better fill ratio. Example- 75 grain bullet, start load 43 grains, Sweet spot expected at 44-45 grains. Again, we have no history for the reamer so play it safe. Watch for pressure signs etc. The smallest bores are very pressure sensitive so make sure you buddy your friend through, make sure his scales are reading true. |

chris murphyRe: .22-243 load datathanks Nathan i came to the similar starting load by looking at load data for a 55grn 243 and backing up a couple of grn for the smaller bore. |
