I had a large Martini (.577-.450) that had been converted to .22LR by lining the bore, for a Miniature Rifle Society in England. The liner was one of the Parker liners judging from the stamp on the crown. My god how that thing shot! I swapped it away due to the fact that even though it shot scary accurately, it bulged cases badly, and ruptured more than a few.
