Ideal was not just sitting on their hands while these other companies were bringing out their new .38 SWC's. The first bullet that Lyman designed explicitly for the .357 Magnum is the Ideal 357443, perhaps the most enigmatic member of the .38 SWC family. Designed for both the .38 Special and the .357 Magnum, it was listed as early as Ideal Handbook #32 (1936), but interestingly not in the regular line of molds, but rather farther back in the specialty mold listing. This unique 160 grain bullet has 3 grease grooves and a minuscule crimp groove in the middle of the front driving band. I suspect that it was most commonly crimped using the top grease groove, only filling the bottom 2 grease grooves with lube, as that dinky crimp groove is virtually useless. The 357443 stayed in the shadows for its entire production life, being quietly dropped from the catalog in the 1960s.
