I just noticed a story at this link with photos and a video about Hornady’s latest thing - a triplex .410. I wonder if they will swap out the red plug for a chartreuse one and change the printing to make it a “Zombie-Max” .410 load? I’d be surprised if they didn’t.
The shell has a non jacketed FTX slug on top of 2 .35 cal lead balls (almost 000-buck). It is definitely on par with Winchester’s PDX1 as far as high-tech .410 handgun loads.
