Agreeing.
The 45 was a bit twangy with no comparison to modern tuned guns of today, even with that recoil bolt through the stock, but back then it's harshness no greater than most of the Magnum powered sporters, where it had one year as being considered better than a FWB Sport before the arrival of the HW77 which sort of killed it off. I'm not certain what happened to them. They just seemed to phase out.
I still prefer preferred the HW35 Luxus and Mercury I had and didn't wade in.
Quite hard to get past a goody HW35, or Mercury for a decent break barrel at that time. Even today perhaps.
