After the success with the Hollow Base Wadcutters in my .44 Spl, I decided to order some 152gr HBWC from Matt’s Bullets. My wife currently uses my GP-100 and 180gr WFN hardcast bullets with Trail Boss as her Bedside Gun. I call them Mouse Fart loads. But, with the weight, they penetrate well. Ever looking for the next best thing, I decided to try these new bullets in a reduced load and launch them from my S&W 340 M&P. Another HD combination for her or maybe a travel gun. I had to seat them rather deep to fit the cylinder. Using Hodgdon’s directions for Trail Boss loads, I measured the case capacity from a loaded bullet and found 4.2gr Trail Boss filled the case to the base of the bullet. Ironically, this is their listed Max Load for Trail Boss and a 158gr cast bullet. That cavity at the end of the round is quite daunting. Being a DAO Snub Nosed Revolver, I set up an unorthodox shooting bench on some railroad ties and leaned a steel target against a mesquite tree 10 yards away. It was time to test accuracy. Recoil was minimal and this too can qualify as a Mouse Fart Load. Even in this diminutive lightweight gun. Velocity clocked 745 fps from the tiny barrel which was considerably more than I anticipated. Honestly, I was expecting 450-500 fps. I was surprised!Set up some water jugs and let fly from 5 yards away. The bullet penetrated 2 jugs. Breaking the back of the second but not exiting, the bullet came to rest at the bottom. With 100% weight retention and only 745 fps from a snub nose.........that ain’t bad for a Mouse Fart Load!!!A better shooter could probably squeak out a better group from a DAO, but I’m kinda happy with the group for a reduced HD load. Me is happy. I have some for my .45 Colt that I need to load and test next. These bullets have grown on me.........
Just reread your first post and realized that you're using your S&W 340! Dang, 745 fps from your 1.875 inch snubby. I'd really like to see what you get from the GP100 with a 4.2 inch barrel. I bet you'll see both the penetration and expansion. I'm guessing at least three jugs with impressive expansion. Also, 13.8 oz M&P versus 40 oz for the GP. I don't see recoil as a problem. I wanna see some water jugs exploding with the GP! 😁You might just have something here.
Be great to have a low recoil load that gets 4 jugs.🐒
Now to get back to drinking the contents of new jugs.Gulp gulp gulp gulp gulp....🍶
