There's nothing wrong with the Lee case length gauge and cutter. The only drawback is that you need to have a gauge for each cartridge. I used to use them for everything, I have since decided that I like to trim the cases manually for rifle cartridges, but for pistol, 38, 357 and 45 I set up the gauge on the RCBS power station. Trim, chamfer and clean the primer pocket all at one shot. No handling each case three different times.
