I think I brought that up in another post about loads for a .44 tracker and I was wondering how slow can you go without losing accuracy or function. With the Lyman manual, the sugessted starting loads start at around 780fps for the .300 gr jacketed sp. However hornady was more speedy with 900fps as a starting. Have any of you played with slowing it down? If so was it worth it? I am looking for a slow round that would transmit all the energy into the target if that's possible.
