I have a bunch of scopes on various rifles including Nightforce, Schmidt and Bender and Swarovski. All of which are great scopes and I am really happy with all of them. I have just completed a new rifle build that is mostly intended for PRS, but I also intend to shoot a bit of F - Class with it too. I was originally intending putting a Kahles K525 on it, but while I was looking I got the offer of an IOR Crusader and Spuhr mount both barely used at a silly price. The extra mag would be useful for F - Class and the scope had very good reviews from people that I respect - so I bought it.
I have now had it a year and it has been on my FTR .308 and 6 Creedmoor PRS rifle. I have shot with it out to 1200 yards. While I prefer the reticule on my Nightforce, the glass on the IOR is excellent and easily as good as my Swarovski. I am not a massive fan of the parallax adjustment, but it is somethng you get used to and I understand why IOR put it there. The Crusader 2.0 has side parallax, but I have it on good authority that it is not quite as good optically as the original.
I never have had any particular reason to question the tracking, but had seen some stuff online about IOR's and poor tracking. The only thing I did find to back this up was the Snipers Hide scope tracking tests. However that test only covered one IOR Valdada that looked like it did pretty badly, but the fact that there was only one tested meant that the results were far from conclusive as far as IORs were concerned. There were a few instances of individual scopes being well off. For me it did look like those particular scopes probably had been damaged in some way prior to the test. My main conclusion was that Kahles looked really good, but I was surprised at the variation found in some other brands.
Nevertheless I decided to find out for myself and have now tested my IOR for tracking over 15 mils (enough for 1400m with the Creedmoor). The first test was carried out at 10 m indoors with the scope clamped to a bench. The second test was shot on a tall target outdoors at 100m. The indoor test was probably more precise and it was easier to check the full range of scope travel multiple times to ensure the scope returned to the same place every time. I am happy to say that in my indoor test the tracking was absolutely flawless and this was confirmed in the shooting test.
I obvioulsy cannot comment on the performance of other IOR scopes, but my one works as it should. In Europe at least they pretty well regarded and havent heard a lot of negative comments from anyone that has a decent amount experience with them. Anyway I hope this is of some help.
