We have been through this before (Remington had this type of ammo 20 years ago)
And the sabots are not very accurate at longer distances.
They are fun and recoil is almost nothing but that's it, And besides Who wants to load a
180 gr bullet in a 460 Weatherby. The ballistics are terrible and there are much better
calibers for a 180 gr bullet.
Velocity sells but so does accuracy and in this business it takes both.
I noticed that they had 50BMG and In my opinion the light bullet defeats the whole
purpose of the big 50.
You can try them but I think you will see that the accuracy is not there at extended distances.
I can only see one place for extremely light bullets and that is in a self defense handgun load that
you wouldn't want to go through several walls after dispatching the bad guy.
Well I suppose you could go with a slower twist, and if it is a sabboted round, then it is probably a plastic sabot. That would require a lot of cleaning to get the crap out of your barrel. I could be wrong!!! If it was a sturdier material then it stands to reason that yes it would be hard on barrels.
First the problem is that the plastic does not engrave well so the rifling does not matter much
but your point is well taken. Maybe with a much slower twist rate they may shoot better but
most rifles are have twist rates for normal bullets and It would not make much sense to build
a rifle arround a single type of projectile because if it did not work you would be stuck with a
rifle that would probably not shoot with any of the normal bullets.
Also when I tested the sabots I found some of them 50 to 75 yards down range others 10 to
20 yards away indicating that they were not opening at the muzzle every time and if they
stay with the bullet very long they will surely effect accuracy.
On the really large muzzle loaders they work well up to 2 to 3 hundred because these bullets are very heavy and travel at low velocities.(But they are still short range bullets in my opinion.
The sabots will also coat your barrel with a film of plastic, It can be removed with special
solvents that are used on shot guns that shoot plastic shot cups. It will not harm your barrel
even with the hyper velocities.
The military uses sabots with good success because the projectile is very very large and the
sabots are in 4 or more pieces and the project has fins to rotate and stabilize it.
As I stated earlier they work well for pistols because they are short range,low velocity,lower momentum (Won't penetrate as well as other bullets) and have less recoil for quick follow
As I said ; Buy a box for your favorite rifle and try them at 400yards+ and the answer will
be in the accuracy.
