I like the big bore slow freight train concept of the .410 in your 45-70, should roll 'em up nicely!

Freight train is about right!

For bigger game, 190gr subx
Small game… 90gr xtp

I load Maker 190gr for whitetail management, 190gr sub-x for hogs and other varmints and 190gr Nosler CC and Midsouth Match Monster for target and plinking. However the Makers have doubled in price since I bought my last 500. So might be moving to Sub-X to replace them once I'm out of what I have. All shooting out of a Christensen MPP 300blk. I will say Maker Customer service is best of any manufacturer I have ever spoke with.

Any bullet designed for supersonic velocity will not open at all. The best you can hope for is for it to tumble but I've had zero success with them except for head shots.

Others mentioned such as Maker, LeHigh, Outlaw State have performed ok for me. In reality 30 caliber subsonic sucks for reliably killing game animals unless you do head shots. A 220-240 grain bullet at 1050fps is only carrying SLIGHTLY more energy than a 45ACP handgun round does.

Apex outdoors makes a 161gr bullet specifically for the 300 BLK. I've had full expansion and petal separation at 900 fps. I just haven't tested below that.

Fast as you can push it 125 SST! sub sonic as above, Maker. Hundred fifty yards and in the SST is lethal.

Why would you choose such a light bullet for subsonic?

If you have to limit speeds to 1050 -- a 195-220 grain subsonic specific bullet would definitely hold more energy-- and some of those heavies will reliably expand down to 600fps if you were so inclined

I'm a firearms instructor for my LE agency and based on the FBI ballistics data that we have the Hornady SubX 190 is the only bullet they tested which reliably expands at subsonic velocities. A judge friend of mine has a ranch where he regularly shoot lots of pigs and he uses the Hornady Subx exclusively, it's very effective on everything he shoots with it be it deer or pigs, coyotes or bobcats. He does limit his range to under 150 with most shots taken at 130 or so. With that said I don't recall seeing Lehigh Defense on the FBI list. Their Maximum Expansion 198 should perform very well at around 1,000 fps. but they ain't inexpensive.

The Sub-X is one of the worst examples of a subsonic expanding bullet, they are very inconsistent when they do expand. The Maker Rex is hands down the most consistent subsonic expanding bullet produced at this time, and it will expand down to 700 fps very reliably.

push the SST to 2500 FPS ! It works fine. I can vouch for it. For sub sonic maker is my choice for hunting bullet. I have a CVA Scout with a suppressor on it in BO. Rides on the seat of my side by side when tending feeder sites. Neat little gun with a really good trigger. Works well in tight blinds. Most of the shots are under75 yards.

Maker Rex
Lehigh Defense
Outlaw State

All are specifically designed and manufactured for subsonic 300 Blackout. Haven't tried any of the others mentioned above.
