A good 240 gr bullet , cast , plated , jacketed works well with 8.5 grs of Unique for a good " everyday " load in Smith 29's . It has plenty of power for most needs including target shooting . If you want something a little lighter , 6.5 -- 7.0 grs of 700X is real nice for about 900 fps . For long distance , flatter shooting , or for less recoil a 215 gr bullet works well .
