Using a fired case in rimfire is the easy way to run. Most of my guns will 'c-ock' on lifting the bolt handle and is reset-ready to fire. I have used the Tipton 'Red' snapcaps but I once had the rim tear off completely, leaving the remainder in the chamber. I only noticed when the 'next round' would not load. Luckily it was another snapcap - woe if it were Live.
I currently use the Pachmayer Orange plastic dummies - they are 'soft' rather than the brittle Tipton caps. And either brand is only good for a dozen or so shots b4 they fall apart. And some of my rifles will not cycle with the Drywall anchors that I have found at H-D - have to stick them in manually.
