I have a sporterized Lee Enfield that is getting scoped as well. For its age and condition it is quite accurate, but 200 meters would be my limit too. After talking to quite a few members of my club, I have reached the conclusion that a high powered scope is not what is required. I am curently looking at variable power scopes in the 1-5 power and 2-7 power. I have a budget for the scope of about 250-300$ all in. I want a scope that has a lifetime warranty, with a service centre here in Canada. To the best of my knowledge, the only producer that has one is Redfield/Leopold. Their 2-7 scopes have 34 and 33mm objective lenses, both have one inch tubes so I am able to use low rings and not come anywhere near the barrel. The only concern, could be the sight picture. On lower power I think the iron sights might be in the sight picture, I am reluctant to remove the sights, as it may be irreversable, so may have to go to higher rings if I can maintain a good cheek weld. Others may have different thoughts.
