Reality is that many/some “5.5” pellets work fine in “5.6” barrels. And, in the old days, 5.6 in 5.5.
There is an issue with older bigger barrels, and it can be a bit hard to find a pellet that works best. But it is neither impossible nor the massive challenge that some think.
And, let’s face it, someone using a .22” Webley Mk3 or BSA Airsporter these days is hardly likely to be using it as a serious hunting or competition tool.
