rc51kid,
If you are looking for saboted bullets, the Hornady XTP's with MMP sabots are about as economical as it gets. You can buy the pistol bullets and get the sabots through MMP. The 200, 250, 300 grain Shockwaves/SST bullets are very common and work well. For Powder the 777 in FFG grade is very common and works very well.
Don't overlook conicals, mine shoots 430 and 460 grain conicals under 1" at 100 yards with scope and 1-1/2" to 2" with a peep sight, when I do my part. 85 grains of 777 FFFG and a .060" thick .518 fiber gasket wad between the powder and bullet. If your shots are 125 yards and under, it just don't get any better than the conicals. Conicals can be had from Bull Shop or No Excuses, you will want them sized at .503".
