Stan, welcome.

Sorry to burst your bubble but no one can really tell you what bullet/powder combo will be best in YOUR GUN. It is really a trial and error process.

I have found 100 g of pyrodex pellets and 44cal 240 Horandy XTP sabots to shoot the well out of my Rem 700MLS 50 Cal. I shot 1" groups at 100 and had no problems taking game with this load. However I didn't start out with this combo, just T&E'd until I found it. I am going to try some triple 7 after this year, as season is on and I don't want to fool around now.
