Have had my 457 since july and put a Hawke vantage 4-16 x 44 scope on it. A lovely gun . I've also got a 452 which i have had 16 years.
The only trouble i have had with both of them is that the spent cases have been getting stuck in the chambers.
I put new claws a spring in the 452 bolt and cleaned the chamber but it still does it.
I have been using winny subs but today bought some CCI, Eley and Norma subs so will be trying them all out in the next
couple of weeks. A few people have been moaning about winny subs. Got a Parker Hale mod on mine.
