I've no experience with WW cases for this cartridge, but I have gotten excellent results from R-P cases. Nosler recommends a max. of 47 grains of Re-19 in R-P cases under their 120 BalTip and 125 Partition as an accuracy load, and it does work well. Either major flavor of 4350 will work very well too. Work these up to about 2900 fps and you'll be cooking with gas. The CCIs will light any of this stuff just fine.
