I think they call them discarding sabots. The Thunderbolt ground support aircraft may also use them. I used it, as do many others, with shooting black powder. The twist rate of the 300BLK was lost on me with all the other factors I was considering, but yes, it might mean a cleaner separation. I'm pretty sure my barrel has a 1:8 twist. In the end it'll either work or it won't. If I had a ballistics lab I'd be able to spend the $ and figure out what works best, but what I have is what I have and it'll either work or it won't. There's very little I can do to help it to work. I nearly forgot. That's the story I get from everyone re: the Rem' accelerators. So I guess my 3" groups weren't all that bad. It just wasn't what I was looking for. After that experiment I bought a .17 Remington and throttled the velocity down to 4060fps from 4200+. The bullets were coming apart in the air. Another thing that your experiment with the sabots from a 300blk may allow using 80gr+ longer high BC bullets loaded to AR magazine length since the cases shoulders are pushed back like they are. Should be a similar situation to how Hornady evolved the 6ARC off the 6.5 Grendel case to load longer high BC bullets. Quote Link to comment Share on other sites More sharing options...
BrianK Posted January 27, 2023 Author Report Share Posted January 27, 2023 The sabots really require flat bottom bullets from what I recall of the way they're molded. High BC bullets would have a boattail and would have huge runout. Maybe it could be done, but I wouldn't know how to do it in a reasonable manner. In the past I found velocity to be almost magical so my thrust is toward that. But I need to find out if they will do the basics of feeding and function reliably. If that doesn't happen it's a failure. One small step at a time. This isn't going to happen rapidly. It'll be at least 1 1/2 months before I even start to think of getting my range melted and usable. . One thing at a time. I don't want to get ahead of myself. First they need the basics, to feed and function reliably. If they don't do that it's not going anywhere. Quote Link to comment Share on other sites More sharing options...
BrianK Posted January 27, 2023 Author Report Share Posted January 27, 2023 Correction (edit): the twist on my barrel is 1:7 I previously stated that it was 1:8 Quote Link to comment Share on other sites More sharing options...
