Sabots in 300 blackout

[BuckKlier]

Has anyone reloaded 300BLK with 223 sabots?

[OldmanFCSA]

WHY?

What's the benefit over shooting a 223 or 5.56 upper?

[BuckKlier]

I would not need to haul around a second upper.

[LarryFlew]

If you are going to shoot 223 anyway why go with 300 to begin with especially considering lost accuracy?

Um, I think you need to clarify what you're trying to say here.

[UnaStamus]

Non-existent solution to a manufactured problem. You want to use 5.56/.223 brass that has been necked up to .308 cal, and then shoot .224 bullets out of it? mmmkay...
Begs the question as to why you would be using .300BLK in the first place.
Why is carrying around a second upper so difficult?

Or to put it a different way, it's like walking out the door, walking all the way around the block, and then walking back inside to kiss your sister...

BuckKlier, if you had looked in the FAQ section, you would have seen that you can't start threads asking simple questions if you don't have 1000+ posts or aren't a cop.

Shame on you

OK, my thought was if I was hunting and wanted to shoot something with a Fmj Bullet (loaded down) on an amimal (furbearing) and not do as much damage as a 30 cal. bullet would do. A guy could put a 5-10round mag in his pocket and be ready to go. I thought it might work, and cycle the action because the gass port in a 300 is usually larger than a .223. And if someone used a mil dot scope, (I do) you could use one of the dots as a aiming point for the sabot round.

To be fair, it would be an interesting project and squeezing extra velocity might make for some fun results.

As usual, asking Google before asking a bunch of argumentative knuckleheads and an 800 pound jackwagon at a Daycare Center is a good idea.....

Where would one start, what powder and what charge????

Well, that would assume that somebody else had worked the whole thing out already with .223 sabots in a 300BLK and had data to share. Considering the website I linked you to DIDN'T have 300BLK data, it's an odds-on bet you may be one of the first people to want to try this. So YOU'RE going to be the Guinea Pig, and it's going to be YOUR butt (actually, face and hands) on the line. My recommendation, FWIW, would be to go with the 30-30 data as it's the oldest, weakest, and lowest capacity round in the list of cartridges shown. Calculate the ratio of internal volume of a 30-30 case to a 300BLK case, scale a 30-30 load back to the degree that a 300BLK case has less capacity, and see what you get. Regardless of whether there is data out there or not, this is a task that CANNOT be accomplished without a chrono. Don't remember if you have one or not. Welcome to the deep end of the reloading pool. Either you got what it takes to figure out how to swim in these waters, or you don't. There ain't no room service and there ain't no menus out here to order from. Quite frankly, I think it's very doable, and you just have to pick the powder and the starting charge.

P.S. Compare the 30-30 Sabot loads with standard light weight (110 grain) 30 caliber loads, and see which way the charge weight goes and also how much faster burning powder is selected for the sabot. That will tell you a lot about how charge weight and burn rates shift going from a light 30 caliber bullet to a 55 - 70 grain .224 bullet.

[FJ540]

I don't know if I'd go sabot in that situation, but I have had some decent success with RN 110gr plated .30 cals in the 300BLK with light loads of trail boss. I don't know if I posted about them here or over on 300BLKtalk.com. The reloading section over there has a ton of info in it, and a bunch of great guys who like doing odd stuff with the cartridge.

Anything lighter than a full load heavy sub or super isn't going to cycle the action. You'll be running single shot either way. Getting sabots to feed reliably out of a mag could be problematic in of itself.

Geez, a guy has an honest question and you go off like this???
