There must be others, but at this point I can tell you I am using a 45-70 rifle bullet (.458) in an MMP .458 Orange Sabot. I am using Nosler 300 grain Partitions, both Hornady and Speer make this bullet and I sure that Sierra does also.

I have seen suggestions the Harvester makes a 50/475 sabot but I have not investigated it. Also I am thinking that PR Bullet in Canada makes a duplex sabot so that you can go down into other smaller rifle bullets.

I have just ordered some Speer .45 Gold Dot HPs, these are Pistol bullets but designed for the 454 Casual - they are quite a bit cheaper than Nosler and seem to have a very superior design as compared to the high end - Nosler - Barnes type bullets...
