    I still can't believe how well my Vudoo .22 feeds. At this point it has seen many, many thousands of rounds in both a GrayBoe stock + bottom metal and an MDT XRS chassis. With the plastic Vudoo mags it continues to feed all the different ammo (lapua, eley, eley CMP, CCI, aguila) that I regularly...

    Gunsmithing Question about marks on shoulder/neck and bore shoulder

    1) The dents on the shoulder appear to be from the brass hitting the brass deflector while being ejected. This is pretty common on AR rifles. Depending on the exact rifle and it's specific timing, those dents won't always be in the same place but they are typically in that area. I suspect the...

    2025 BigJimFish Review / Article blog: More 350L, Garmin and Athlon Chronos, Leopold Mark 4HD, BurstFire, Field Optics Research, videos and visits

    Update 6-16-2025 The Leupold Mark 4HD 4.5-18x52 arrived a couple days ago for review. I have been thinking about doing an unboxing video more or less as content padding for YouTube. Since I wanted to talk a little about my thoughts on the Mark 5HD I reviewed a few years ago relative to this...

    Precision Rifle Gear New Athlon Rangecraft Chronograph-Garmin Xero Killer?

    OMG, that is hilarious. The number of periods........ I can feel his frustration. I have to feel for gun companies when it comes to apps. In almost all cases these apps are contracted by the gun company with a third party software company and these software companies seem to have a very silicon...

    Precision Rifle Gear New Athlon Rangecraft Chronograph-Garmin Xero Killer?

    Wow, those are some very, very, close results. 2.3 fps average difference between the "slowest" and "fastest" of the devices. From a curiosity standpoint, It would be interesting to know which is the closest to the true result though it hardly seems that this knowledge would have any real world...

    Vudoo closed the doors…

    So, I've been following this Vudoo mess a few days now since it showed up on my radar. Wow, sure have learned a lot about how things ran at Vudoo between this and Mike's thread. Since, like everybody else, I couldn't seem to get a hold of the Vudoo people I contacted Three Sigma manufacturing...

    Kelby's Prometheus Action

    This is the factory tour video I mentioned. In it me and Ian go through the factory and see where everything is mentioned while talking both generalities and specifics on how that manufacture is done. There is also a second video I should have up soon where we sit down and talk about specific...

    Update 5-14-2025 As mentioned, I am planning to do a number of site visits to some of the Ohio based manufacturers of precision rifle products this summer. The first of these is with Kelbly’s who I have known for 15 years dating back to a review of a March 1-10x rifle scope I did back when...

    I have a few thoughts. First off, thanks for stepping in and providing a source for parts kits and the cost effective poly magazines. I'm sure I'm not alone in intending to continue to run my Vudoo indefinitely. Without question it is the rifle I shoot the most and enjoy the most. .22lr just...

    Precision Rifle Gear New Athlon Rangecraft Chronograph-Garmin Xero Killer?

    I thought it was 3.30. That's actually why I hadn't updated the Garmin again. I thought I dodged a bullet on that one. Until near the end of the Garmin review I hadn't updated it's firmware at all. I was totally satisfied, why would I. I only updated it to be thorough in the review and cover the...

    Update 5-5-2025 It rained me out half way through work today so I decided to jump ahead and do an indoor range run with the new Athlon Chrono today instead of waiting. Of course, I set it up side by side with the Garmin for the comparison. Boy was I in for some big surprises. Side by Side at...

    Xero C1 Pro - v3.30 update

    I really thought I had dodged a bullet not having installed the 3.30 update. The last one I did was 3.27 and I did that one only at the end of my review cycle when I was making sure I had investigated the various software features thoroughly as I didn't use the app for my own use. Turns out I...

    X - Vectronix Shooting Solutions

    I played with the Calypso pairing again last week. The option now exists in the Calypso software but I was not able to get the vector X and the Calypso AB to actually pair. It looks like something the AB guys are actively working on at the moment as every week or so there are new updates on the...

    What Optic Are YOU Running?

    The big things are that whatever you use needs to focus close (25 yds or better) and have a ton of elevation (35 mils is great if you can get it). You might not think you will, but you will use all the elevation. .22lr drops super fast because it is subsonic and not aerodynamic but in most cases...
