Both my Winders are "chambered" for Short, but both will accept a loaded LR round. It is just like loading a cartridge into a match chamber. Accuracy with the slower twist barrels is not good, but there do not seem to be any adverse impacts on either rifle or cartridge case. You don't have to "rechamber" a Winder. But if you have one in Short and are after accuracy with 22 LR, you need a new barrel. I shall try the CB-match Longs for accuracy at 25 & 50 yards as soon as I can get a couple of boxes.
