To be fair to your younger self, I am sure that it was pretty cool!
The 766 always found an early grave. Back in the day it was the aspirational gun of teenagers who wanted a Remington Nylon 66 like their American counterparts, but could not have one. A couple of AGW's more fantastical writers sold it as a recoil-less miracle, capable of stunning accuracy and power. One of them shot ducks with it (DUCKS, FFS!). Others, like 'Harvey' (I think that was his name) and Mr Cardew were less enthusiastic, knowing it was not at all an improvement on the scacely more expensive BSA Mercury, or the unpatriotic HW35.
What you actually got was a plastic and monkey-metal pumper that was less powerful and accurate than a standard BSA Meteor and which required a massive amount of clack-clack-clacking to get it up to steam, and then you had the fiddly loading and the oh so heavy and creepy trigger pull to deal with ... the power generally dropped off fairly quickly as the valves got scorched from over-pumping and then the accuracy went to pot when the tiny grub-screw which held the straw barrel in place got loose. It was never designed to last more than a few thousand shots and is one of the few rifles which has a far stronger and durable stock than the barrel and action.
If you chopped it fore and aft, then I am not surprised, the thing bloody well deserved it. I'm sure it looked like a Remington pump-action shotgun like villains down the Mile End Road would love to get their 'germans' on. Leave it aaaaaaaaaht!
The Remington Nylon 66 ... get one and enjoy the real thing!
