The Feinwerkbau 700 and Walther LG 300 are also models to consider as they are both top class match rifles that have been superseded in their manufacturers ranges and so they can be found at competitive prices - even new!
Some international shooters still use these previous models so if they are good enough for them not to feel the need to "upgrade" then they should also be good enough to help you on your way to achieving your ambition - but at a more reasonable price.
Rossendale Target Shooting Club. Every Tuesday and Thursday evening 7 - 10pm.
