Found a 22 pellet that fills up the prewar larger barrels

[Happiness Stan]

Was made aware by a friend of mine H&N made the FTT in 5,55 and ordered some to try.
They do a VERY good job in my early BSA's and another friend uses them in his Webley pistols with great result.

Oh,That's good to know.

Thanks.

Anyone else given these a spin down an old 5.56 barrel?
