Is that last sentence a typo??
Nope, a Hankins with Rem 700 CF action and Krieger 45cal barrel will shoot a Parker 275gr bullet at 3000fps with 78gr of 4198. He uses his own LRMP module and breach plug design.

He no longer uses a Knight breach plug and nipple. Its a custom breach plug with a tungsten bushing. They last for many hundreds of shots before the bushing wears out. I know of one with over 400 rounds though it and its still within spec.
Cool video, notice how easy they load
