RE: SCOPE MAGNIFICATION
As said there won't be that much difference. Like PaJack, I would want more of 24x or so. However, a quality 14 or 16 power is way better than a cheap 24x. I know. I have a cheap
6x24x50 I had on my flattop AR15 and beyond about 16x, it gets too dark and grainy unless in bright sunlight. Even then it's nothing to brag about. We were prairie dog hunting but I ended up using it on 16-18x most of the time because 24x was so bad. Again, it was a cheap (Simmons) scope so I got what I paid for.
I don't know anything about Sightron scopes so I can't say if a 14 or 16x would work fine for your intended use.
