    Vortex Razor HD Gen III 6-36x56

    It is entirely possible that this is just a case of blind "going with the flow". Or it could simply be that different people shoot differently. Or it could simply be the case that depending on where you are different reticle make more sense. If it is simply a case of "mokey see mokey do"...

    Vortex Razor HD Gen III 6-36x56

    If that ratio persists and is representative of the broader customer base, it likely signifies that there is a market there for non-tree reticles. Hell, S&B did not have anything resembling a proper tree reticle in a precision scope (other than Gen2 XR in one model) until recently and they are...

    Vortex Razor HD Gen III 6-36x56

    I decided to run a poll on reticle preference on my website. It is a little bit of a self-selecting sample, but so far it is roughly 2-to-1 in favor of tree-type reticles over hash-type reticles with exactly zero people favouring Horus-style grids. We'll see if that changes as more people vote.

    Is the 6.5CM barrel still available?

    FOV issues and patents

    I would need to look. I see that there was one from 2020 that was abandoned https://patents.google.com/patent/US20200201020A1/en?oq=US20200201020A1 It has been a while, so I need to look again. ILya

    Bushnell customer support (or lack there of)

    Vista's shareholder meeting was supposed to be today, so maybe there will be some news. They sold RCBS to Hodgdon. All their sporting goods stuff was put together into The Kinetic Group and as of a couple of months ago, CGS was going to buy it. Outdoor brands including Bushnell were bundled in...

    FOV issues and patents

    Traditionally, field stops that restrict the FOV are there to hide some distortion and image issues at the edges of the FOV. There is a little bit of a tradeoff between FOV and eyebox, all else being equal, so adding a field stop will often help with eye releif flexibility. ILya

    FOV issues and patents

    They have stacked a couple more patents under it, so unless there is a challenge, this is not ending any time soon.

    FOV issues and patents

    Well, I do not know who they have agreements with, but I know with a great deal of certainty that there are several riflescope manufacturers out there who do not have any agreements with Swaro on anyone else regarding this and are happily making products with wide AFOV, 30 or 34mm tubes and 5x...

    Steiner C35 Gen 2 - Initial range trips and first hunt - Updated 9/30 with third hunt

    Hard to say. Machine shop timeline promises are notoriously unreliable. I am testing a prototype. It is looking pretty good so far. If I do not find anything to change, it will go into production in a matter of weeks not months. ILya

    FOV issues and patents

    As I have mentioned in the past, I do not think this patent should have been granted (on technical merits). However, it has been granted and all over the world. It is very much up to Swarovski to use it or not use it as they see fit. In Europe, it did not survive scrutiny and was revoked. I...

    FOV issues and patents

    The fact that it is overturned in Europe does not really mean anything for the US unless it gets challenged here via the IP Review process or something along those lines. IP is not really my strength other than a brief stint as an expert witness in a patent challenge. I did find it...

    FOV issues and patents

    From an optical design standpoint, IOR was quite innovative back then. The 3-18x42 was ahead of its time, warts and all. Naturally, they screwed up the execution more than a bit and then the market kept moving forward and left IOR behind. ILya

    Did Steiner just quietly build the MPO we have all been asking for? H6xi

    Blaser 1-7x28 does that. The technology exists with diffractive reticles. Dual focal plane reticles acomplish the same thing via different means. ILya

    FOV issues and patents

    Kahles is owned by Swarovski, so this patent is of no concern to them. ZCO and the new Tangent use a 36mm tube as well, which might be more pertinent. However, they both keep AFOV at less than 22 degrees. Whether that has anything to do with Swaro's litigious nature is anyone's guess. ILya

    FOV issues and patents

    I just read the Board of Appeals decision. Basically, they looked at the 2-12x32 IOR that was out there before Swaro's patent and realized it has those same negative lenses, 6x erector, AFOV of 22degrees or more and a maintube in the right range. The funny thing is that his explains why Terry...

    FOV issues and patents

    I am not a lawyer, so my understanding of this process is somewhat limiting. I do know that challenging a patent can be done by almost anyone. However, by the time the lawyers are done with you, it will be well into seven figures and take a couple of years.
