Recently acquired a .38 M & P Model 2, serial number indicates it was made in 1903. It's a shooter but so am I. My favorite target load for my k-frame .38's is 3.8 grains of HP-38 using 158 grn. semi-wad cutters ( Missouri Bullet Co.). I also have a number of commercial boxes of Winchester- Western " mid-range- super match" 148 grain wad cutters that should be mild enough for a gun that's 116 years old in excellent mechanical condition. Any comments would be greatly appreciated. Thank you for your time and expertise.
