A few weeks back I mentioned Wadcutters as a type of bullet. I had a box of same down on the bench, old Speer with the lube wax dirty with age. I loaded some up today. The Book says they do best at 900 fps – that works out to 3.0 grains of Tite Group:

Wow. Not much compared to rifle rounds. That’s barely going to cover the bottom of this new .38 Special brass. Ripe for double or triple charge mistakes. We’ll be very sensitive to quality control.

Before and after.

And does it punch nice clean holes in paper? Yep.

Upper left at 25 yards is 6 rounds out of the 4” barrel of the Taurus; the rest from the 2” barrel of the colt. 842 and 795 fps respectively.
It would have been nice to shoot some 3, 7, and 10 yard groups, but the Action Bays were being set up for an IDPA match.

Lessons learned? Yes, size your new brass before reloading. Pretty tight, otherwise. Live and learn.
