I have an RCBS plastic funnel, circa 1980, and it works fine with 22 caliber cases.
20 years or so ago, I bought a Frankfort Arsenal, or what ever Midway was using for a brand name at the time, funnel with interchangeable ends so that I had a funnel that works with 17 caliber cases. It works fine as well.
They do not get used much as I find my powder measures, particularly the Harrell Precision Culver 90, does more than a great job at consistent charges.
