I had NMS which resulted in complete Renal failure, taken three years to recover but as my odds only 10% I am very lucky. Sadly it cost me my fifteen year relationship at Christmas and my three year old son. On the up side shooting again! I have my home tuned HW77 back, its Maccari springed, V Mach seal and my own transfer re-profile plus cross hatched cylinder and buttoned piston. It has a great adjustable stock but when ill sold my scope's along with all my guns. Lucky to get 77 back but it was in the family. Still shoots superbly even if it is a .22
