Sabots for centerfires

I'm wondering about using sabots in centerfire rifles. Does anybody have any experience with this?

My main objective would be to try this in .45-70. I love the gun, but would love if it shot flatter. I wonder if there's a way to shoot, say, a 30 cal, 35 or even a 40 cal with a sabot, and thereby get higher velocities and flatter trajectories. Side benefit might be less recoil.

I can also see how it would be cool to have maybe a .224 bullet loaded in something like 270 or 308 for an ultra-flat shooting varmint round.

Are the components available for this kind of thing? Are there problems with shooting plastic down your barrel? Just wondering.

Interesting idea. I am curious if anyone here has done it with the .45-70. I googled "45-70 sabot" and a few things came up that might be worth looking at, including a few recipes with .357 and .40 bullets.

On the .224 sabot in a larger case, your post made me think of the Remington "Accelerator" rounds. I thought they had stopped production, but Midway still lists them in 30-06 and 30-30:

30-06 (4080 fps claimed): http://www.midwayusa.com/viewproduct/?productnumber=220009

30-30: http://www.midwayusa.com/viewProduct/?productNumber=366971

Although they don't list .45-70 or .270, this place has components for .308 and others:

Sorry I don't have any experience with it, but I am curious to read the responses of others.

3700 fps is some serious velocity...adios barrel life
The manufacturer linked above claims one of the benefits of the sabot is less frictional wear of the sabot and consequential increased barrel life compared to conventional rounds. Of course they are trying to sell a product. They also claim no build up of copper or lead residue, but it would seem that there would likely be plastic residue that isn't mentioned?

A quick search finds that there are a least a few people that agree on the barrel life. Here's one of those easily found:
