I always find it amusing when folks talk about needing really low power. Perhaps it is just because of the terrain I am used to but this year's whitetail was interesting. I was watching a bunch of does at ~300 yards and noticed a buck. I took aim - but he was quite small - and my hunting partner encouraged me to pass, so I did. I was just putting my rifle down when two does burst out of the brush in front of me - right behind them was a nice buck. I brought my rifle up and followed him as he was trotting and chasing through some fairly open area. I was just waiting for him to stop. He spun around and changed direction - my partner let out a grunt and the buck stopped. I shot him. He was at just over 40 yards and my scope was still on 12x. It didn't cause me any trouble at all. Like I said, maybe it is just because of where I hunt, but I can't see the need for less than 3x.
On the other hand, here in BC, we can shoot from 1 hour before sunrise to 1 hour after sunset. I find that any really good quality scope with a 42mm obj is fine for 1/2 hour before and 1/2 hour after. But if you want to use every minute of legal shooting light you need to have high quality optics, a larger obj lens and importantly the proper reticle. As a side note the hunting partner from the above story has been using a 3-12x56 Diavari for probably close to 20 years. He loves it.
one of the best comments ive read in a while....if u cant find the animal in your scope at 3 power u need to take pointing lessons
