I would suggest that anyone asking for advice on this or similar topics should supply a little more detail. This has already been asked for in some responses, I think.
There is a great deal of expertise on this site, and we can all benefit from it. I'll still be discovering something new on shooting every day until the final summons.
This topic is a wide subject, and needs more facts like rifle type/calibre/'scope size and type/ intended use .... and so on. If a questioner includes these the answers might be more relevant and helpful to them.
