40 some years ago, I used 14 gr 2400 behind a 210 grn Sierra SJHP as a service load in my 41 Mag. M&P

I fired a round at a fleeing Ford Bronco and the bullet went through the spare tire,the tubing mounting device on the back of the tailgate. It continued on thru the tailgate and the back of the front seat and took out the radio in the dash.
I wanted loads that would enable me to deal with people in and behind vehicles.

That load did what I had in mind.

They durn sure weren't fun to shoot, but they did the job when I needed them. I used 15 grns for practice loads.

I have been doing a bit of shooting with Elmer's 38/44 loads in a pre-war Outdoorsman. They are hot and accurate and show no signs of over pressure.
