I shot many-many hundreds of plain 148 Grain, Lead semi-Wads, which were not sized, and which were intended for .38 Special...in my Model 1902 'Sporting' Model Autocolt.
I'd downloded them...they worked beautifully for Paper Targets of 15, 25, and 50 Yards.
I my have been foolish...it was long ago and I was not as educated as now.
I used 'Bullseye'...and, merely emulated a light .38 Special target Load.
6 Inch Barrel, slower Powder probably would be more forgiving and allow higher velocities if one wanted, with less strain...as would sizing the Bullets for the Bore...
Never saw any pressure issues...Slide was happy...easy recoil...
I'd like to get an old Ideal or Lyman Mold for the old 'Snowball' Bullet...these were .356, and...ohhhhhh, 135 grain?
Anyway...9 mm handles higher pressures than .38 Colt Automatic...but with 'Lead', in either, for any given powder loading, there should be less strain than Copper Patch I'd think.
I wonder how 'Trailboss' would be for for something like this..?
