I don't know if this is the case with WR, but I've heard some shotgun designs are having trouble with the new special steel shot proofing for high-performance steel shot cartridges.
From here:

High-performance steel vs standard steel
Guns who have shot the odd standard steel load (most guns ‘Nitro’ proved to at least 930 bar will comfortably handle standard steel loads) may fail to realise that the box of cartridges they have just purchased are in fact high performance steel.
The latter should only be fired through guns that have passed steel shot proof and have been proved to at least 1,320 bar.
