I'm in the market for a new rifle and scope setup and am currently looking at a Remington LTR in .308 with either a hunting or tactical scope. I would use the rifle for hunting and target plinking to about 800 yards. I believe I would like to get a tactical scope for the ease of adjustment for long range plinking but I am unsure about using one for hunting. Forgive me if this sounds stupid but I don't know much about tactical scopes. Specifically I would like to know: 1. Do the tactical scope knobs tend to get dirty/gummed up after some use due to there being no caps over them for protection? 2. How easily would the knobs move? Meaning, while walking though thick cover am I likely to bump them and then my zero is out of alignment? 3. Any other pro's and con's of using a tactical scope for hunting would be appreciated.
