I have always chosen the Winchester Super Match WC (X38SMRP) if I can find it, but expect it to be expensive. After that, the Federal Gold Medal Match WC (GM38A) is my 2nd choice. When I am wanting a similar load (bullet style, weight, etc.) but lower cost, mainly for plinking... I have used Sellier & Bellot Wad Cutter (SB38B).
