Just an update on the Lee Speed .Restoration is almost complete.Have decided on using Hornady 338 interlock 200 grain bullets .These bullets have about the same BC as the original 303 diameter bullets 215 grain bullets and i intend to drive them at about 2200 fps so the cape sights work out.My initial load was 37 grains of 4064 in Winchester neck sized 338/303 cases at just about 2100 fps.No pressure so i will be working up a load .Any powder/load references or opinions are welcome!Wish I knew how to post pics from my computer.
Further reloading has brought me to 40.0 grains of IMR 4064 which is IMR's starting load data for the 338 Federal .Note; although the 338 Federal has virtually the same water capacity as my 338/303 case ,(the 338/303 being slightly larger)that pressures are much higher in the 338 Federal specs . I am stopping precisely here ;2,300 + fps velocity in the 200 grain Hornady with little pressure on a cool spring day. I will test this load on a "Kalahari Hot" summer day and I may drop it one grain .Accuracy is excellent with the original Cape sights ;no scope needed (for Patterson or myself)
