IIRC about 7 yards or so for myself. I've also tried 38 rimfire loaded with 9mm flobert ball ammunition, improvised with a tiny bit of smokeless pistol powder in the small case. At about 3 feet I had maybe 1/2 inch penetration. (3 3/4" barrel) Yeah, not inspiring.Good test! That's lots enough power. How far were you from the target?
I was trying some .30 rim fire in a 2 & 1/4 in. barrel, with treated spruce 6x6 in my backstop. At about 15 ft., I could pick the bullets out with my thumb nail. But they'd still realy hurt.
