Problem with a lot of load combinations is what may shoot well out of one gun may not be so hot out of another.

Most all major brands of jacketed 240 grain bullets should shoot well once a good load is found. I have usually had good success with Nosler, Hornady, and Sierra bullets to name a few. The 240 XTP is an excellent deer bullet. A lot of shooters have reported, in general, that plated bullets seem a little less accurate than a jacketed or good cast bullet. Coated cast are becoming very popular, and reportedly seem a little more accurate overall than plated as well.

When it comes to cast, it is important to match the bullet with the chamber throats for good accuracy and reduced leading. Most newer Smiths have relatively tight specs, so .430 / .431 should work well. Check yours by pushing a bullet through each throat by hand. They should be tight.

2400 is an excellent upper mid-range / full power powder. For cast bullets at fun level velocities, I have always had good luck with Red Dot and Win-231.
