I have been waiting for the 1.5-8×32 ER5 to hit the stores for a little while now, but since it is not quite here and I wanted to take a look at the ER5, I asked Leica if I could borrow whichever model is available.

The available model turned out to be the 2-10×50 with the Magnum Ballistic reticle.  While I was at it, I sorta inquired if the Magnus scopes are already here and it turned out that they were.  I was extremely impressed with the Magnus when I saw it at SHOT and while it is a very expensive scope, it is easily one of the best optical systems I have a seen in a riflescope to date.  Since the opportunity was there, I got my hands onto the 1.8-12×50 Leica Magnus as well.

As has been my custom lately, I sat down in front of the camera and recorded some initial thoughts on the two designs as soon as I had received them:

It is not entirely clear to me what would be appropriate comparison items for these scopes, but I have a few that roughly compete in this category and I will procure some others as applicable.  The scopes that I have on hand that are probably most relevant are Kahles KXi 3.5-10×50 and Docter V6 2-12×50 (this scope has been living on my Tikka in 280Rem and I like it a lot).  The Magnus is, of course, in a very different price range and I should probably try to compare it to some of the upper end Swarovski and Zeiss hunting scopes.  While I try to get my hands on them, I can do an image quality comparison against some of the better tactical scopes I have here, like the 3-15×50 Tangent Theta.

Simply looking at the specs, nothing jumps out all that much except that the FOV of the Magnus is substantially wider that all the other scopes I have on hand, and, pending a more thorough check is probably the widest FOV I have seen to date.

I will talk a bit more about my impressions of the performance of these scope once I spend some time with them.  In ‘first look” type articles I generally focus on specs and features, so I will largely stick with that.

Magnus that I have here is equipped with an exposed elevation turret and covered windage turret, which is an arrangement I like.  The exposed elevation turret has a zero-stop and covers 12 mrad in one turn.  When I first saw that, I had some reservations about click quality, since it is not a very large diameter turret and I do not like it when the clicks are too close together.  Those reservations turned out to be unfounded: the feel of the clicks is calibrated very well.  I will spend some time on checking the tracking, of course.

The Magnus I received  is equipped with the Ballistic reticle.  I am sorta on the record as being not a huge fan of ballistic reticles in SFP scopes, but, just like the Kahles KXi, this one works well for me because at top magnification, it basically becomes a mrad scale.  Interestingly, the space from the center of the crosshair to the first has is 1 mrad, but after that, you get hashmarks every 0.5 mrad.  Horizontal hashmarks run 1 mrad and 2 mrad wide.  All in all, it is a prtyt straightforward, but unobtrusive reticle that gives me reasonable ranging and holdover capability without looking messy.

The fact that the space between the center crosshair and the firs hash is a little larger than the rest of the mrad scale, weirdly helps draw the eye to the center crosshair for quick shooting.  That is something which was not apparent to me when I first saw the scope, but mounting it on a rifle helped.  Once you look through the scope and turn reticle illumination on, that reasonably clean center crosshair really helps with speed.  Illumination, while we are at, is done very nicely.  The control turret is low and wide.  It is mounted on top of the eyepiece and is equally easy to use for right and left handed shooters.  There are two preset positions for day and night use (you can tune the presets) and the day setting can be very bright, easily visible in the brightest of light levels.  The low level is very low and does not seem to have any apparent effect on my night vision.  In this regard, I think, all the top end scopes use a similar scheme and it works well.

The reticle I got in the ER5 is called Magnum Ballistic, and it is a more conventional holdover design that I am generally not a huge fan of.  Also, the listed subtensions look a bit odd to me.  They sorta make sense for the high magnification models, but as they are listed for the 2-10×50 that I have here, the do not match any cartridge I can think of terribly well.  It is entirely possible there are some typos there, so I will reserve judgement until I get it on the gun and do some testing.  One thing that is interesting with the Magnum Ballistic reticle is that it is designed to zero at 300 yards or so and it provides both hold over and hold under features.

That is not a bad way to go, since for many typical centerfire hunting calibers, a 300 yard zero gives you a pretty good MPBR when you need to get a shot going quickly, while the additional reticle features aid with precision.

Before I wrap up, I also want to point out that both Magnus and ER5 are pretty easy to get behind with well designed eyepiece.  That really helps usability and as good as ER5 is in that regard, Magnus is one of the best I have seen to date.
