My curiosity button was pressed a couple days ago. I have a bag of .41 mag SWC cowboy ammo that I punch paper with occasionally, and was wondering if anyone had done any backyard penetration tests with it. I know it wouldn't have any expansion to speak of. Advertised at 800fps, and about 300ftlbs at the muzzle. Specifically what do y'all think about this as a Home Defense round? It has considerably less recoil and flash than my usual Underwood XTP (1560 fps, 1135 ft. lbs.), but do y'all think the trade off would be acceptable at in-home distance for the usual common break-in type bad guy (no armor)?
