At last i found a good load for 38 Short Colt.
Used 6,5 grains 3N37VV. H&N 158 grains Hollow Point, OAL 31 mm. The speed between the slowest and fastest load was 347m/s and 355 m/s (1138 fps 1164 fps) No problem with major factor:-) Only problem is unburned powder, not much but enough to make an fast reload to be an slow..
Im gonna buy some N350VV and make some loads to see if it can be better..
