I, too, like the Lyman 311-041, and even have it noted as "Best for .30WCF" in my mould listing of Lyman moulds. (See photo). Albeit it's been three or four (?) years since I regularly shot .30-30, I enjoyed the 150gn 311241 with my "one" dislike that it's plain base -- no gas check. However, it performed well in my .30-30 Remington. Interestingly, my notes indicate I cast, loaded, and shot more of the gas-checked 170 grain # 311291 in the 1894 Winchesters -- I have two of this mould to enable my casting them in tandem.
ALL great bullets for the .30WCF.
