hey guys, i found a great local deal on a zeiss conquest 3-12x56 and i was going to simply use a regular 3-9x40 but i wanted to ask...

will using the 56mm be BAD in any way? I think eye relief would be better but im not sure...

im already going to buy talley lightweight mounts for my Tikka so i assume im going to need the high ones.


p.s. i know this is similar to another thread but i didn't want to thread jack another member.

sounds good - enjoy.   What you get is an optic that will be brighter in low light at higher powers especially at  8x to 10x you would see a big difference.

Depends...better in low light, but heavier and longer, maybe harder to get a good cheek weld. I have different rifles for different kinds of hunting and one has a compact scope and 20" barrel while the other is 24" and a has a 3-15X50. That rig weighs 2 lbs more and isn't as manueverable. But I like for antelope (and other open country) hunting. If I could only have one, it would be the lighter rig for sure.

A 56mm may seem large, bulky and out of scale on that Tikka rifle. However, do as you like. I do! Good luck.

Just like many other equipment selections, a 56mm scope is great for some uses, not so great for others.  There are always tradeoffs, and you have to decide which tradeoffs are worth it.  If your focus is on low light hunting, and you frequently require greater than 8X while hunting in low light, the 56mm scope provides a useful benefit in usable light transmission.  All else being equal, larger objectives can provide a marginal improvement in resolution, but it may or may not be noticeable.

If you don't want a bulky scope, a 50mm objective may provide a good compromise between good low light performance and reasonable compactness.
 
If you don't usually use more than around 6X - 7X in your low light hunting, a 56mm objective provides no useful benefit over a 42 - 50mm scope of the same optical quality.
 
If you value a low mounted scope and less rifle weight and bulk, a high quality 36mm - 42mm scope will do everything you need to do and will still povide good low light performance up to 6X or so.

+1 what that man said. If you hunt off an ATV or from horseback the 56MM will be somewhat cumbersome in a scabbard and a little more susceptible to getting knocked around. The 56mm will show its advantages in a bean field situation.
