I have been using a cast bullet from a Lee 405gr. mold and 40gr. of Rx-7. I was thinking of getting Lee to make me a mold of the same bullet cut down leaving 1 grease groove (it has 4 now). This should make it around 200gr. + or -. My purpose for wanting to try this is that I would like to use it on smaller game and I think a 405gr. slug is a little over kill for coyote and such. Assuming I use all the same components and same charge my questions are....                            #1 How much more velocity? (about 1500fps now)                                         #2 How much difference in pressure?                                                           #3 How much flatter trajectory?                      Thanks for any help, JTT IN NC
