tucker joy, I have several suggestions, which may be at odds with some of the above. First, the quick & dirty measure of cast bullet fit is to take #311332, as cast, and insert it gently into the muzzle of your rifle. If it drops in up to the drive bands of its own weight, you will not get match grade accuracy from it. Second, if -332 fits your bbl., you'll still need to slug your bore or do a pound cast of its throat. You can then determine the correct diameter to size your CB to. Third, rather than spend lots of $$$ on bushing dies, try the Lee Collet Die (more information about it here http://castboolits.gunloads.com/showthread.php?392156-Lee-collet-neck-size-die). Lastly, once you get this stuff sorted out, try something like 18 - 20gr. 5744 or 19 -20gr. IMR 4198 as your test loads: you can always work up (or down) as needed. Hope this helps!
P.S. Is there a chance your new bore is rough and could be broken in/smoothed via firing several hundred jacketed bullets through it? If you opt for this, look up C.E. Harris' method for doing so.
