The Lee and Sierra manuals have load data as does the Hodgden website.I have been working up loads for my Dtech 6X45mm AKA 6mm/.223 and have been getting 3100 fps from the 65gr Hornady Vmax and 68gr Berger with H335. Reloader7 and H322 also were very accurate but with slightly less velocity around 2950fps. I have not shot these loads past 200yds yet but with a 200yd zero they are just under 1 inch high at 100yds.
