I have an older Contender, given to me by my brother, who bought it, knowing no more about it than I do. It has a Thompson Center Arms 'scope marked 4RP, Does this mean it is a 4 power? It doesn't seem very powerful. When one shoots this, do you have your arms fully extended, or half way bent, to see thru' the 'scope? I have a .223 barrel, a 6mmtcu barrel, and a .357 Rem, Max barrel. Which of the last 2 would be best for deer? Would they be good for black bear, or elk? Are there any 'scopes that have more , or larger field of view? The view seems to be better thru' the 'scope if it's held closer to the eye. I haven't shot it yet, I have a book coming from Amazon some day, if they ever ship it. Appreciate any and all help or suggestions. Thanks
