Just picked up a used 640 2" ss ,38 special SN BNF9xxx and I am interested in any possible info on gun like year and any other particulars, and maybe any reload ammo sucess in lswc and w231 powder (was sold 105 gr. due to gun size?? and cannot find a load in my manuals they said to start with 4.8 and go up ) or maybe I will just take them back for 125's. Thanks in advance.
