What might shoot in CVA MRX 45 Cal ?

[Oldranger]

Forget the Powerbelt (CVA) ELR.
Factory shot that at over 2.0 moa.
Bore measures 454 / 460.
A Fury 452 totally free falls down the barrel. I pushed a Harvester 45 sabot with a 400 down with good resistance
until about 6 inches from end of rifling and it free fell out the breech. So, I'm guessing I'll need some obturation.
Bullet to bore not an option ?
Any suggestions would be appreciated.
Save the buy a real ML comments as
Jeff Hankins has one in the mail to me.

I run the Barnes 195g MZ Expander with a HLBS in my 45cal. If I were you, I would start with the supplied tan sabot first. That bullet did the trick on a buck I shot yesterday.

If you could find them.

MidwayUSA has them in stock right now.

I changed from the Harvester to the MMP Sabot. It was much tighter going down the barrel.
