im wondering if anyone here has had much success with reloading their own sabots. im looking mostly for 30 cal as i do not yet own a BMG. how well do these DIY reloaded sabots work? accuracy? i assume the 30 cal uses the 223/5.56 bullet as the projectile in the sabot? are these going to be comparable to the sabots that are factory loaded? this has struck my curiosity, and am considering picking a few up. are they a novelty that's not worth the effort & $ or are they worth it? thanks |

hmmmm i wonder where i was reading that the accuracy was supposed to be better. something about not having the rifling affect the ballistics so it travels more uniformly.
i would not doubt accuracy is affected though, as the sabot can not be that great of a medium of transferring the energy, nor releasing from the bullet it self. |

I think Remington made the Accelerators. If I recall correctly accuracy was poor. The problem is/was with the plastic sabot not releasing concentrically from the bullet.
Sabots can be accurate. I don't know about now but when I was in the army the M1 Abrams tank fired a AP sabot round from a 120mm sooth bore barrel. We used them with devastating effect on Iraqi tanks at very long ranges in Desert Storm. |

That's a great theory. The problem is that usually the projectiles used for us normal folks are not designed to fly at the combination of speed and rpms they are subjected to when fired as a sabot. As either goes up, smaller and smaller manufacturing imperfections have bigger and bigger effects, and with lead core + copper jacketed bullets, they inevitably occur. This is probably why most of the sabots used in military arms are solid, single metal constructions, and not one or more metals pressed into each other. For some reason it works in muzzle loaders, but they're usually keeping bullets under 2000 fps and twist rates slower than 1:12 for a theoretical max rpm of 2000. |

Well I've used 'em with fair to good results........certainly game hitting results........in '06 using both 55 and 69 gr. .22 projectiles. (note that none of mine were what I could honestly call sub minute of angle loads!!......but then again, accuracy is a relative term..............lots easier to hit a tank than a miniscule varmit)
What I could not accomplish was the reason I originally bought the things for, to attempt to create a usuable sub caliber round in the 7.62/25 cartridge.....even with reduced power springs I could not gain reliable function and some of the loads I attempted are really scary in retrospect. Is the sabot concept usuable? My take is a qualified yes, depending on the type of action you are using, the caliber and presuming you have the patience to work up a load..... |
