As stated, crimp step not needed in most bolt action cartridges without significant recoil.
I use the Lee Factory Crimp die but ONLY on lever action cartridges with older tubular magazines: the 348 WCF, 33 WCF, and 45 -70 in Winchester 1886 and early Model 71 rifles.
The Lee FCD must be used carefully, regardless.
RCBS dies used on 90% of my reloading from 270WCF through 375 H&H, up to 450 Alaskan.
The Lee FCD in 450 Alaskan is rare and requires careful adjustment-but it really works well, as the 450 Alaskan cartridge generates substantial recoil in a lever action Model 71 with 400 gr bullets.
